Product Description

Product Description

Self-operated Flow and Temperature Conbined Control Valve(ZZYP)

Summary:
Self-operated flow and temperature combined control valve do not need the external control instrument. It can be adjusted by the pressure of the pipe itself. It is controlled by multiple combinations of components. It is mainly composed of a control valve with a set flow rate, an actuator and a temperature controller with a fixed-point control valve. Self-operated flow temperature combinated control valve is suitable for non-corrosive liquids. As for the flow and temperature control in the system pipeline, the principle of priority action should be followed, and two parameters cannot be controlled at the same time.
