RESILIENT SEATED FLANGED GATE VALVE, PN 10/16 (TH001)

A.Stem sealing

Three independent stem seals offering triple safety: * A NBR wiper ring protects a gainst dirt from outside.

  • A polyamid bearing with 4 NBR O-Rings protects against galvanic corrosion.

B. Body/bonnet connection

The unique assembly of the valve body and bonnet ensures a durable tightness: x* A round rubber bonnet gasket fits into a recess in the valve bonnet preventingit from being

blown out by pressure surges.

  • The 8.8 galvanizes bonnet bolts are countersuock 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

†o the medium or soil.

C. Wedge nut

The fixed wedge nut reduces the number of movable valve parst 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.

D. Vuicanized wedge

The ductile iron core is fully vulcanized with drinking water approved EPDM rubber internally and externally. No iron parts are exposed to the medium and the excellent rubber vulcanization prevents creeping corrosion underneath the rubber. Quides in the wedge and on the valve body ensure a uniform closure regardless of high pressure.

Safe operation is ensured, as the guides prevent overloading of the stem. The wedge has a large though bore and as there are no hollows in the core, stagnant water or impurities

cannot collect and cause contamination.

E. Operation

Valves could be operated by hand wheel/head cap/worm gear/electric actuator etc.

according to the customers” requirements.
