Gate Valves - Resilient Seat
CIVILPIPES resilient seated gate valves are certified to AS 2638.2 and are suitable for use in potable water, non-potable water and wastewater systems installed above ground and below ground.
Gate valves are designed, as pipeline isolation points, to be operated in either the fully open or fully closed positions; and are not suitable for throttling applications.
The high strength and corrosion resistant materials provide long life protection and the EPDM encapsulated ductile iron wedge ensures a drip tight seal.
Options include:
Anti-clockwise closing or clockwise closing,
Rising spindle option for above ground fire services,
Handwheel or gearbox actuators,
Valve extension spindles
