Basic performance of pneumatic butterfly valve
Basic performance of pneumatic butterfly valve, terminology of pneumatic butterfly valve and basic performance of time terminology 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 all of it will be discharged 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. The pneumatic butterfly valve can be directly driven by the system pressure at the valve inlet. In this case, the mechanical load provided by the spring or heavy hammer overcomes the medium pressure acting under the valve disc.
