Product features

The self operated flow and temperature combination valve does not need external control instruments. It can be adjusted by the pipeline's own pressure. It can be controlled by multiple combinations through the assembly, which is mainly composed of a control valve with a set flow, an actuator and a temperature controller with a fixed-point regulator. Self operated flow temperature combination valve is applicable to the flow and temperature control of non corrosive liquid in the system pipeline. It works according to the principle of priority action and cannot control two parameters at the same time.
Self operated flow and temperature combination valve
Features of self operated flow and temperature combination valve:
 
The self operated flow and temperature combination valve has high safety and is commonly used in the situation without electricity and gas source. It has no hidden danger of external energy and is simple to operate. When setting, it only needs to rotate the adjusting nut. It has the advantages of pressure balance function and high sensitivity.
