Rubber Seated Gate Valve
New Products From This Supplier
►1.Stem sealing
· A NBR wiper ring protects against dirt from outside.
· A polyamid bearing with 4 NBR O-rings protects against galvanic corrosion.
►2. Body/bonnet connection
• A round rubber bonnet gasket fits into a recess in the valve bonnet preventing it from being blown out by pressure surges.
• The 8.8 galvanized bonnet bolts are countersunk in the valve bonnet, encircled by the bonnet gasket and sealed with hot melt. Thus there is no risk of corrosion as the bolts are not exposed to the medium or soil.
►3. Wedge nut
The fixed wedge nut reduces the number of movable valve parts thus minimizing
the risk of corrosion/malfunction. The wedge nut is made of dezincification resistant
brass with lubricating abilities providing compatibility with the stainless steel stem.
►4. Vulcanized wedge
The ductile iron core is fully vulcanized with drinking water approved EPDM rubber internally and externally.
