SPECIFICATION

These gates are made as per STEINBOCKVALVES design.

APPLICATION

These gates are mounted on the face of a wall and are used to isolate flow in and out of a conduit.

FEATURES

• Flange / flat back frame design for direct mounting on face of wall using anchor bolts with a rubber gasket in between frame and wall.
• Open top frame comprising of HDPE guides to prevent galling between shutter and frame during gate operation.
• Shutter comprising of plate reinforced by stiffeners of same material to withstand the applicable head.
• Water sealing on two sides, top and bottom achieved by forced contact between non corroding face of shutter with replaceable type rubber sealing mounted on the periphery of gate frame aperture.
• Frame mounted adjustable type HDPE wedges on sides and top as required.
• Provision of adjustable wedges reduces constant seal wear while opening and closing of gates and thereby enhances seal life.
• Offered for seating as \,!ell as unseating head applications, as required. Gates offered for seating head application provided only with adjustable side wedges whereas gates offered for unseating head application provided with adjustable side and top wedges.
• Provided with threaded stem connecting block housed in shutter to connect the shutter with the spindle.
• Rising spindle gate with lift mechanism mounted on separate platform above gate frame to transfer thrust reaction on platform.
• Single piece or multi-piece spindle, as required, to connect the stem block mounted on shutter to the gate operating arrangement.
• Couplings, as required, to connect the multi-piece spindles.
• Fixed type stem guide brackets, as required, to guide the spindle.
• Manual lift mechanism to enable a single person to operate gate with effort less than 20 Kgs.
• Anchor bolts with nuts and washers, as required, for frame extension guides, stem guide brackets and pillar of lift mechanism.
• Gate assembly made of corrosion resistant material for longer life.

MATERIALS OF CONSTRUCTION

Depending on application and requirement, the client may select and specify the material of construction for various components from the alternatives stated in out construction materials table.
