Butterfly Valve
Motorised and pneumatic-actuated butterfly valves, wafer type, tight shut-off.

Butterfly Valve
Our wafer-type butterfly valve is built for tight shut-off and is offered both as a motorised assembly — automated with our own QT-series electrical actuator through a dedicated valve mounting bracket and coupling — and as a pneumatic-actuated assembly for fast-cycling duty, optionally fitted with a positioner for proportional control.
Body and flange are available in Cast Iron, WCB, SS304 or SS316 investment casting, with a CF8/CF8M disc and a choice of Nitrile, Neoprene, Butyl, EPDM, Silicone or Viton seals to suit the process media and temperature.
Engineered For Reliable Performance
