1.Introduction: 

multi-function regulate valve is combined by a main valve and other control valves. It is specially used in refrigeration system using fluoride refrigerant and ammonia refrigerant, and in controlling the pressure & temperature in air regulate equipment. RCV32 multi-functional regulate main valve can be installed at the sides of high pressure, low pressure, wet-suction, dry-suction pipes, etc.

multi-functional regulate valve’s function depends on the control valves to be chosen. The control valves are mainly for receiving signal, Control the action of the mail valve, they are controlling valves. Main valve is a huge execute mechanism, it is a regulate valve. 

The advantages of such combination are: 

a) Enhancing the general usage, can be applied in many control requests; 

b) Can choose to use one or more conduct valves to control the mail valve, in resulting more control effect. In order to ensure more function happening on one valve. 

multi-function regulate valve is connected by thread between main valve and control valve, it can also be used by pipe to connect.
