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

Air driven wafer butterfly valve
Confirm the required air-supply pressure and operating time for the selected valve, actuator and control accessories under the actual load and installation conditions. The required stroke time should be agreed and verified for the supplied assembly rather than inferred from a general air-pressure statement.
