Home Pneumatic Diaphragm Pressure Regulating Valve
Product Description
This product is equipped with multi-spring diaphragm actuator, light weight, small size and stable output force. The air source acts on the diaphragm inside the actuator to overcome the spring reaction force for linear movement. When air supply pressure disappears, the compressed spring rebounds to push the push rod to reset. The actuator has direct acting and reverse acting types. Matched with valve positioner, high-precision pressure regulation can be realized. The valve body is equipped with pressure feedback pipeline to stably control pipeline medium pressure, suitable for process pipelines such as petroleum, chemical industry and natural gas.
