What is the working principle of pneumatic butterfly valve?
Pneumatic butterfly valve is a kind of pneumatic butterfly valve, which is mainly used in pipelines and various pressure resistant devices. When the working pressure of the medium exceeds the allowable pressure value, it will automatically open and discharge the medium. When the medium pressure drops, the valve will be closed again to prevent the danger of overpressure in the safety pipeline and equipment.
Basic performance of pneumatic butterfly valve and terminology of pneumatic butterfly valve Pneumatic butterfly valve is used as overpressure protection device in pressure equipment, vessels or pipelines. When the pressure in the equipment, vessel or pipeline rises above the allowable value, the valve will automatically open and then discharge completely to prevent the pressure in the equipment, vessel or pipeline from rising continuously; When the pressure drops to the specified value, the valve shall be automatically closed in time to protect the safe operation of equipment, vessels or pipelines.
