cage seat regulating valve is a valve with a pressure balance type, body fluid channel was streamlined S, is also provided with a sleeve surrounding fluid to improve the smooth flow of the guide wing, has the advantages of small pressure drop loss, large flow, wide adjustable range, the flow characteristic curve of high precision, good dynamic stability, low noise little corrosion, cavitation. Valve equipped with multi spring diaphragm actuator, compact structure, large output force. Proper control of high temperature, high pressure difference of fluid temperature.
