DescriptionHydro Gate fabricated slide gates are designed and fabricatedfrom special shaped extrusions or structural angles, flats, andplates are assembled by welds and bolts. Through years of fabricating experience, Hydro Gate has developed techniquesfor fabricating parts to a close tolerance and straightness. Sincethere are no machined parts or wedging devices in the gateitself, the gate depends upon water pressure and seal design toseat the fabricated slide. Fabricated slide gates are usually furnished with rubber seals to improve water-tightness. They are designed for either open channel use or aperture type

applications. Open channel gates have no frame member orseal at the top of the slide. These gates will overflow. Aperturegates (over an opening) have top frame member and seals toshut off flow at depths greater than the slide height.

A more economical fabricated gate is available without rubberseals for flow diversion. It is not as water tight and relies onhead pressure and presence of silt and fine particles to reduceleakage by plugging.

Head capacity is dependent on opening size and availability of structural members. The most common head rating is 10 ftseating and unseating, with 20 ft seating being a practical limitfor most sizes. Higher heads require special designs. Consult

the Hydro Gates Engineering Department for additionalinformation.

Materials Hydro Gate fabricated slide gates are available in four differentmaterial combinations.

Material Combination 1: Carbon SteelThese steel gates can be grit blast cleaned and painted to yourspecifications.

Material Combination 2: Galvanized Carbon SteelAvailable for those installations where a very economical gate isneeded but painting does not provide adequate protection.Both of these material combinations use hot-rolled angles andflats for gate construction.

Material Combination 3: Stainless SteelThis material is recommended when corrosive conditions makeit necessary to add protection. These Hydro Gate fabricatedslide gates are made from Type 304, 304L or 316 stainlesssteel. Gates manufactured from these materials are morecorrosion resistant under most conditions than slide gatesmanufactured from other materials.

Material Combination 4: Aluminum Various extrusions are utilized with this design. Frame sides aremanufactured from an extrusion that forms the guide slot andprovides flange back mounting. This special extrusion also canbe used for gates fully embedded in concrete channels. Analternate extrusion is used for hand-pull gate frames.

NOTE: If low leakage characteristics are desired, the seriesHG561S gate is recommended.

Aluminum Hand-Pull GatesHydro Gate manufactures several standard sizes of hand-pullor stop gates. An extruded metal section embeds in the side walls or is mounted on the face of the rectangular flume orconduit and acts as a guide for the gate slide. The gate consistsof an aluminum plate reinforced if necessary with handholes

for manual opening of the gate. A hand-pull gate is aneconomical way to divert water in rectangular channels.

Material Specification The side guides, slide plate and any necessary reinforcing for Hydro Gate hand-pull gates aremanufactured from aluminum meeting the requirements of ATMS Specification B209 Alloy or B308 Alloy 6061.

Weir GatesMany treatment plants require downward-opening fabricatedgates to permit a rough measurement of flow or to maintain aconstant upstream water elevation. For these installations thegate slide is moved down to allow the flow of water over thetop of the slide or weir plate. Sufficient room must be left on

the gate side of the wall to permit the slide to travel downwardfor its maximum specified opening. Every effort should bemade to mount the gate so it will be subjected to seating head.

If the gate must be mounted in an unseating position, seals arerequired along the sides and across the bottom of the gate. Weir gates mounted with unseating pressure, particularly widegates, are subject to greater leakage because water pressuretends to deflect the slide away from the seals.

Most weir gates are required to be considerably wider thanthey are high. Gates up to 20 ft in width are not uncommon.Such a gate may be only 24 to 30 in. high. Tandem lifts andstems must be utilized to ensure alignment of the slide as it israised or lowered. As a general rule, when the width is greater

than twice the height and the width is greater than 60 in., atandem stem arrangement should be used. Either manual orelectrically actuated lifting devices may be utilized. Weir gatesmay be self-contained or not self-contained.

Weir gates are available in Material Combinations 1, 2, 3 and4. If additional information on gate size, lift selection, etc., isneeded, contact your local Hydro Gate sales representative.

DescriptionThe HG561S Stainless Steel Slide Gate is an exceptionaldesign for low leakage requirements in corrosive environments.The frame, slide, stem and fasteners are all stainless steel type304 and 316 dependent on your application. The side guideseal assembly utilizes an ultra high molecular weight polymermolded and milled to positively retain the slide and form a watertight seal. The polymer provides a self-lubricating surface with a very low co-efficient of friction, ensuring smoothoperation. The guide seal assembly is designed for positive

retention allowing the compression force applied to the slide tobe completely adjustable. All Hydro Gate seals are factory adjusted and after years of service the design provides theability to readjust the compression force applied to the slideensuring years of reliable service.

A top wedge system is utilized on gates 24 inches and wider.The Hydro Gate wedge system incorporates a similar designused on cast iron slide gates. Each wedge is securely fastenedto the top of the slide, which when in the closed positionprovides a contact with the top seal of the frame. Both flushbottom and standard bottom closures are available with thismodel. The flush bottom design features a neoprene sealattached to the frames eliminating the need for a recessed

floor. The standard bottom incorporates the same design as thetop wedge system.
