Easy to Install and ServiceThe reduced size and weight of the Shutter Valve means that it is easier to transport, install, and service. The user-friendly design also makes it possible to disassemble and rebuild your Shutter Valve very quickly during scheduled service intervals,

to help your maintenance team maximize uptime, with less manpower.

Low EmissionsThe Shutter Valve is the first control valve to earn the strin-

gent API 641 certification, virtually eliminating the fugitive methane emissions that occur with traditional valve stem

designs, and which account for a large percentage of refinery methane emissions.

Lower Cost, Greater ValueOur valve is a safe replacement for globe valves used in

standard service process control applications, yet it requires only a fraction of the raw material to produce. The result

is a valve that is priced 50% to 80% less than an equivalent globe valve.

The Shutter Valve™ is a quarter-turn control valve, with a patented design derived from aerospace methods for fluid

control, sealing, and mechanical systems. Three interlocking petals form the adjustable aperture of each valve, smoothly pivoting with precise motion in the valve body, to transition

from a tight shutoff to full-port operation.

Low TorqueThe Shutter Valve’s interlocking petals open perpendicular to the flow direction of the liquid or gas being controlled, requiring a fraction of the mechanical force used to oper-ate a globe control valve with an equivalent C

V. This allows

for cheaper, smaller, lighter actuators that consume much less energy and take up much less space.

Longer LastingThe Shutter Valve’s curved petals are CNC machined to the ideal precise shape to dramatically reduce the cavitation and turbulence experienced with common control valve designs, even at high pressure drops. This significantly decreases wear on the valve mechanism and downstream piping, to ensure greater uptime and lower maintenance costs.

Compact and Light WeightThe unique geometry of each Shutter Valve delivers equiv-alent flow rate (C

V) to common globe valves, from a valve

body as small as 1/5 the size and 1/5 the weight, while still meeting or exceeding ANSI B16.34 wall thickness requirements.

Precision ThrottlingThe three interlocking petals of the Shutter Valve deliver dynamic and precise flow control, suitably replacing most globe valves with 500:1 rangeability and very low torque requirements, from a valve that is 1/5th the weight, size, and cost. We can also replace ball valves, providing zero pressure drop and up to Class VI bubble tight shutoff.

When precision counts, the Shutter Valve shines. In both batch and continuous operations, having the ability to control media at varying temperatures, pressures, and flow rates is key. Whether in the petrochemical, specialty chemical or fine chemical production environment, the Shutter Valve provides precision process control and tight shut off up to 4,000 PSI. From a fine mist all the way to full bore opening, the Shutter Valve gives the flow control you need without the negative impacts of cavita-tion that other types of valves create.

The Shutter Valve is designed, engineered and packaged to meet the industry’s strictest applicable standards for performance and safety. With solutions for boiler feedwater, cooling water, and even glycol applications, the Shutter Valve provides precise flow control for process optimization. It uses a compact design to help make the most of your flow control system.

Advanced Water SystemsPopulation growth and climate change are driving the need for viable, non-tradition-al ways to create drinking water, such as through desalination and recycling. The water industry must also find ways to maximize the continuity of this supply and ensure that it remains available for as long as possible. The industry’s aging infra-structure causes further complications for plants, including frequent repairs and unnecessary leaks that increase operating costs and deplete the water supply. The bubble tight, ultra-reliable Shutter Valve is the perfect solution for your advanced water system needs.

Oil and natural gas touch our lives in countless ways every day. Together, they supply more than 60 percent of our nation’s energy. Helping the oil and natural gas industry optimize plant operations is a key feature of the Shutter Valve. Providing plant operators with precision flow control and full-port operation from a compact design is what makes the Shutter Valve superior. Whether your application requires manual or automatic actuation, the Shutter Valve delivers.
