Aquavault - Resilient Seat Wedge Gate Valve
The Aquavault® resilient seat wedge gate valve is designed in the UK, made for pipeline isolation and suitable for buried service.
WRAS approval ensures safe potable water handling, while its unique lightweight ductile iron construction provides an excellent weight-to-strength ratio with low maintenance requirements.
The valve's wedge guides and rolled spindle thread have been designed to reduce operating friction, whilst corrosion is inhibited by the wax-filled fasteners and high chromium stainless steel spindle. Additionally, stem seals are replaceable when under pressure and lifespan is maximised due to the integral captive wedge nut.
