An energy-saving control valve without external energy sources, used for flow control in process equipment involving non-corrosive liquids, gases, steam, etc.
Does not require any external driving energy
Has pressure balancing function and high sensitivity
Does not require maintenance, with reliable performance
Low noise, smooth operation
Adopts modular design, with high levels of standardization, seriesization and generalization
Material: WCB、CF8、CF8M
Nominal Size: DN15~250mm
Pressure Rate: PN1.6~4.0MPa
Voltage Regulating Range：0.02MPa、0.05MPa
