    WH Parson goes with the flow at leading valve

    manufacturer Hattersley Newman Hender

    Valves play a critical part of most industrial processes,and Hattersley Newman Hender has been making them for

    over 100 years. The company now has 9500 item lines; it

    sells two million valves every year. It is a world leader in what

    you might call the flow business, with a 60 per cent share

    of the market. The company has 300 employees; annual

    revenue is 30 million. Hattersley valves are used in the

    heating and ventilation industries, in office blocks, schools,

    hospitals, petrochemical plants and water works. One in

    four Hattersley valves is exported, with many ending up

    operating in some of the worlds most hostile environments.

    The origins of Hattersley Newman Hender go back to

    1897, when 20-year-old Richard Hattersley owned a small

    tool-making business in Halifax. In the early 1900s he

    relocated to Ormskirk, and in 1910 he joined with three other

    engineering companies, including Newman Hender & Co.

    of Woodchester, to form United Brassfounders & Engineers.

    The company was probably the most comprehensive group

    of its kind. By 1937 Hattersley and Newman Hender both

    enjoyed worldwide sales, with Hattersley exporting to some

    73 countries. During the Second World War, both companies

    entered war production, making fuses for armaments, brass

    rods for munitions factories and, of course, special valves

    for military purposes. After the war, the two companies

    diversified, and Hattersley expanded its overseas interestsby buying a substantial stake in the large Australian valve

    company M B John, and establishing Hattersley (Canada) to

    develop business in North America.

    Considerable investment was made in an advanced

    manufacturing plant at Ormskirk, and in 1981 a sophisticated

    new cast iron foundry came into operation. Built at a cost of

    4 million, the fully automated foundry had the capacity to

    increase the output of castings by up to 40 per cent, producing

    192 tons of castings per week. In 1984, the company was

    one of the first to receive BS 5750. This was followed by BSI

    Kitemark quality awards for its range of copper alloy gate,

    globe and check valves, draining cocks, and metric cast iron

    gate, globe, check and waterworks valves. Quality awards

    came from abroad too, when the Milliken lubricated parallel

    plug valve was approved by the Under-writers Laboratory

    in the US and the Canadian Gas Association, as the fruits

    of the continuing investment in production plant began to

    appear during 1985 and 1986. In a move to boost its on-

    going quality control programme, Hattersley installed a new

    computer assisted tri-axial inspection centre, which gives

    rapid highly accurate measurements over a wide variety of

    castings.

    During this period the company introduced what is

    probably the most sophisticated valve production system

    in the world, a 5.5 million flexible manufacturing system.

    It followed a three-year evaluation involving companies

    throughout Europe. The British-built, computer-controlled

    system can manufacture over 2500 component variations,

    and in buoyant market conditions operates 24 hours a day,machining over 100 tonnes of castings per week. At its heart

    is a group of sophisticated FM 100 machining centres, with

    special-purpose out-facing machines, fed by automatically

    guided vehicles that move components and fixtures around

    the system.

    In 1992 the foundry under went a major redevelopment

    at a cost of 1.6 million to install two six tonne electric

    induction furnaces to replace the coke fired cupolas.

    Hattersley continued to develop new products for heating

    and ventilating with the introduction of cast iron products

    for grooved piping systems in 1995. That year also saw

    the introduction of the next generation of balancing valves

    when the Autoflow range of automatic balancing valves was

    launched. Designed for use on both constant and variablevolume systems, Autoflow significantly reduces the amount

    of commissioning time required to balance large systems. In

    1990 Hattersley entered the industrial valve market when

    the Millcentric eccentric plug valve was developed for the

    waste water industry, and the Milliken Valve Co. was formed

    in Bethlehem USA to develop sales of the valve in North

    America. In 1996 the range of industrial valves increased,

    with a range of ductile iron knife gate valves for the pulp and

    paper industry. In 1998 a stainless steel range was added.

    Stainless steel ball valves were also added to the range thatyear, to cover the requirement for smaller sizes.

    Throughout its long history, Hattersley Newman Hender

    has enjoyed a growing reputation for quality and reliability.

    The company has more kitemarked products than any other,

    and a recent survey showed that most of its customers prefer to

    stick with Hattersley rather than be tempted by less reputable

    rival products, even if they sometimes seem to be cheaper.

    Hattersleys reputation continues to win it big contracts

    both at home and overseas, in both public and private

    markets - and most recently, in a big PFI project. Hattersley

    is supplying valves for the 45 million refurbishment of 20

    schools in the Kirklees area of West Yorkshire. The two-and-

    a-half-year project is the biggest improvement programme

    undertaken by the council since the school building boom of

    the early 1960s. Temporary classrooms are being replaced,

    heating systems improved and new science and technology

    facilities installed and built. The average school contract

    for Hattersley is worth between 5000 and 15,000. The

    bulk of the valves being supplied by Hattersley are bronze

    isolating and commissioning valves used in low temperature

    heating systems.

    Contractor EMCOR Drake & Scull have an 18-month

    nationwide agreement with Hattersley who provide them with

    a tailor-made range of valves to meet its needs at a specially

    negotiated rate. The project is the biggest Hattersley has

    been awarded involving a local authority private finance

    initiative. Over the next five years, the company plans to

    expand into other lucrative new markets both at home and

    abroad.

    Hattersley Valves for Massive Projects in

    Kuwait

    The Avenues is a 425,000 square meter site, set to be

    Kuwaits premier shopping, leisure and business destination

    when completed in 2010. Businesses within the complex

    will include 216 retail stores, a ten-screen cinema complex,

    restaurants and 15000 car park spaces. Hattersley

    balancing valves and strainers are currently being installed

    as part of the HVAC systems within phase one of the projects

    scheduled to be open by the end of 2007.

    A range of Hattersley valves including balancing, gate,

    butterfly and strainers are being installed within the HVAC

    systems of Al Safat American Hospital under construction at

    Sabah Al-Salem in Kuwait. This 120-bed general hospital is

    intended to be near paperless, with all medical records kept

    in electronic form only.

    The third project in Kuwait to have Hattersley valves

    specified this year is a huge commercial office tower in

    Kuwait city. Al Babtain Waqf Tower is to have Hattersley

    valves installed throughout its 40 stores; the whole buildingdesign represents a symbolic palm tree.

    Biggest ever order for Hattersley

    Valve manufacturer Hattersley is currently involved in their

    largest ever single order - supplying control valves for the

    massive Terminal 5 Heathrow airport construction project.

    Hattersley valves are to be used within the various hot

    water, condenser and chilled water systems, air handling

    units and the heating, ventilating and air-conditioning

    systems throughout the terminal buildings, tunnels, plant

    room and service areas.

    To meet the demanding specifications across the wide

    range of applications, many different valve types and sizes

    need to be supplied. These vary from bronze and cast iron

    ball and butterfly valves ranging in size from 65mm to

    700mm and hundreds of commissioning sets.

    This is a major contract for us, said Hattersley Business

    Development Director Martin Pride, In fact it is the single

    largest order we have ever had. We have set up a T5 Team

    within the company to manage the production control andsupply chain operations and to maintain liaison with our

    contracting partners.

    Terminal 5 is one of the largest construction projects in

    the UK, phase 1 alone consists of 16 major interconnecting

    projects and 134 sub-projects. It extends far beyond the

    construction of the terminal building and includes 41 aircraft

    stands, two satellites, a 4,000 space multi storey car park, a

    new control tower, the creation of a new spur road from the

    M25, the diversion of two rivers and an airport perimeterroad. Plus over 13km of bored tunnel, including extensions

    to the Heathrow Express and Piccadilly Line services.

    The T5 program is making extensive use of prefabricated

    components and building services modules. The manufacture

    of prefabricated components and sub-assemblies will

    be carried out in many locations throughout the UK and

    Europe.

    Phase 1 is scheduled to be complete and operational by

    spring 2008.

    Hattersley Valves Control Ricoh Arena

    The recently completed Ricoh Arena, home of Coventry

    City FC, has Hattersley valves at the heart of the HVAC

    systems.

    As well as providing a new 32,000 capacity stadium

    for Coventry City that includes 72 executive boxes,

    bars and restaurants, there is much more to this vast

    72.5 acre site. Situated alongside the M6 at junction 3,

    the complex also includes a 65-bed hotel, 6,000 square

    meters of exhibition/concert hall, 3,000 square meters

    for conference and banqueting, 8,000 square meters of

    office accommodation and a 9,000 square meter casino as

    well as a 2,000 space car park.

    The entire construction programme began in January

    2004 and the football stadium was ready to host the first

    match of the new season in August 2005. During that

    time Building Services contractors Haden Young designed

    and installed services using a range of Hattersley valves

    including butterfly, Auto flow, fan coil compact hook-up

    units and commissioning sets. These are controlling the

    heating, ventilating and air-conditioning systems around

    the football stadium including the hospitality boxes and the

    hotel complex. Final elements of the entire construction

    programme were completed in early 2006.

    Hattersley valves throughout new Manchester

    Hospital

    Hattersley valves have been specified

    for installation throughout the heating,

    ventilating and air conditioning systems,hot and cold water and domestic

    systems at the massive Manchester Royal

    Infirmary re-construction project.

    Manchester Royal Infirmary is a

    working hospital where the construction

    is being carried out in stages, allowing

    departments to move into the new

    areas as they are completed. The

    vacated areas are then demolished and

    re-constructed, until the entire hospital

    will be re-built. When completed, the

    hospital will be known as ManchesterJoint Hospital.

    Thousands of valves from throughout the Hattersley

    range are being installed by M & E contractors Rotary

    North West. A new Energy Centre has been constructed

    and is now operational; this will serve each new block,

    each of which will have individual plant rooms.

    In addition to the many gate, globe, check, ball and

    butterfly valves used within the project, Differential

    Pressure Control Valves and Compact Hook-Up modules

    have been included. The Compact Hook-Ups areprefabricated modular management systems providing

    flow control, measurement, flushing and isolation of fan

    coils and other terminal units. Compact Hook-Ups are

    extremely quick and simple to install and factory testing

    ensures trouble-free operation.

    Hattersley were also able to provide a solution to

    potential health risks associated with domestic systems

    with the supply of their latest combination valve, Multi-

    Therm. Paul Jones, Hattersley Area Sales Manager

    explained, Multi-Therm helps protect against Legionella

    by providing thermal disinfection. Legionella bacteria

    will not survive above 60C. Multi-Therm switches offregulation functions when hot water temperatures are

    increased to above 70C and automatically switches to

    the disinfection setting.

    As well as protection against Legionella, Multi-Therm

    also provides self-balancing thermostatically controlled
