Valves
Gate Valves - Resilient Seat
CIVILPIPES offers an extensive range of BETTA resilient seated gate valves that are certified to AS/NZS 2638.2.
The gate valves are suitable for use in potable water, non-potable water and wastewater systems installed above ground and below ground.
Betta 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 and clockwise closing,
Rising spindle option for above ground fire services,
Actuators - Handwheel and gearbox options,
Valve extension spindles,
Valve anchors - SS straps and Anchor legs
