The pneumatic wafer butterfly valve uses air as the driving force of the actuator, and switches through single acting or double acting Actuator. It can be used for 4-20ma analog adjustment of valve opening after the positioner is assembled.
Pneumatic control wafer butterfly valve
The actuator is made of aluminum alloy and stainless steel screws. The outside is painted with epoxy resin. The top is equipped with a switch position indicator. The double action is without a spring, and the single action is equipped with springs on both sides. The actuator can be countered by the spring to control the opening or closing of the butterfly valve
