Aquavault - Resilient seat gate valve, DN50-DN300, PN16, EN558-2-S3

Why choose the Aquavault?

Designed in the UK, the Aquavault is a unique lightweight ductile iron design that provides a reduced weight-to-strength ratio, as well as a low maintenance solution, this makes the resilient seat wedge gate valve such an innovative design.

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.
