SVAHX-S Powder Butterfly Valve

Feature & Principle

The pneumatic actuator receives air signal to drive the valve plate to rotate, so as to open or close the flow channel of powder medium. The special flexible seal can compensate the gap between valve plate and valve body to prevent powder leakage. Fail-safe design is optional, the valve will return to preset position when air supply is lost. It can be equipped with limit switch to feed back valve position signal to PLC.
