Resilient seat gate valve, DN50-DN300, PN16, EN558-2-S3
Starting from £30.00
Aquavault® resilient seat wedge gate valve to BS5163 / EN1074, flanged EN1092-2 PN10/16, WRAS approved and used for isolation duties with clean water.
Designed in the UK, the Aquavault is a unique lightweight ductile iron design which provides a reduced weight to strength ratio, as well as a low maintenance solution. The wedge guides and rolled spindle thread have been constructed to reduce operating friction, whilst corrosion is reduced due to the wax filled fasteners and high chromium stainless steel spindle. Additionally, stem seals are replaceable when under pressure and lifespan is optimised due to the integral captive wedge nut.
