Features
- Fixed, integral wedge nut prevents vibration and ensures durability.
- Scalloped Flanges.
- ISO, F10/F14, mounting gland flange for the safe and cost effective fitting of gearboxes and actuators
- 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 can’t 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 safety stem seal: a polyamide bearing with two O-rings, and another O-ring on stem, which prevents leakage when exchanging stem seals under pressure
- Round bonnet gasket fixed in a recess groove in bonnet preventing it from being blown out by pressure surges
- Countersunk and sealed bonnet bolts encircled by the bonnet gasket, thus there is no risk of corrosion
- Blue fusion bonded epoxy coating.
- Body, bonnet and gland bolts sealed with hot-melt.
- Embodied carbon data available upon request
