PN10 DN40 Resilient Seated Gate Valve with Epoxy Coating for Sea Water and Potable Water Systems
PN10 DN40 resilient seated gate valve engineered for demanding applications including sea water, potable water, and industrial fluid systems. Features epoxy powder coating for superior corrosion resistance and WRAS-approved EPDM rubber components.
- NBR wiper ring protects against external contaminants
- Polyamide bearing with 4 NBR O-rings prevents galvanic corrosion
- EPDM rubber manchette provides main hydraulic sealing
- Replaceable O-rings under pressure ("DRY THREAD" design)
- Round rubber bonnet gasket secured in recess prevents blow-out during pressure surges
- Countersunk stainless steel bonnet bolts encircled by gasket and sealed with hot melt
- Complete protection against corrosion as bolts are isolated from medium and soil
Fixed, integral wedge nut made of dezincification-resistant brass with lubricating properties ensures optimal compatibility with stainless steel stem, reducing movable parts and corrosion risk.
- Ductile iron core fully vulcanized with drinking water approved EPDM rubber
- No exposed iron parts to medium, preventing creeping corrosion
- Guides ensure uniform closure under high pressure and prevent stem overloading
- Large through bore without hollows prevents stagnant water and contamination buildup
