Flange butterfly valve

The rigid lined PTFE manual and pneumatic lug butterfly valve combines a pneumatic actuator and a worm gear operation box. The fluorine lined manual and pneumatic dual-purpose lug butterfly valve can be equipped with PFE, PFA, or PTFE valve seat liners. With a handwheel operation, it can be used to turn the switch in case of air source or power control failure in the lug butterfly valve. The fluorine lined lug butterfly valve can be equipped with limit switches (feedback devices), air filters (pressure regulating valves), solenoid valves (electrically controlled directional valves) and other accessories.
