Product Description

Product Description

 

Feature of Resilient Seated Gate Valve:

Fixed, integral wedge nut prevents vibration and ensures durability
Stem seal replaceable under pressure
The ductile iron core is fully vulcanized with drinking water approved EPDM rubber, no iron parts are exposed to the medium and the excellent rubber vulcanization prevents creeping corrosion underneath the rubber
The wedge has a large through bore and as there are no hollows in the core, stagnant water or impurities cannot collect and cause contamination
Stainless steel stem with rolled threads for high strength
Full circle brass thrust collar provides fixation of the stem and low free running torques

Double stem seal: a replaceable polyamide bearing with two O-rings and an O-ring on the stem
Round bonnet gasket fixed in a recess groove in bonnet preventing it from being blown out by pressure surges
Bonnet bolts encircled by the bonnet gasket to protect against contact with the fluid and against corrosion

Bonnet and gland bolts sealed with hot-melt for protection against corrosion
