Constant Pressure Regulating Valve- RSA Series

Short Description:

RSA is made up of one main valve AM1 and one regulation pilot valve. Different pilot valves can make different regulators:
AM1+ACVP-L(0 to 10bars) can make RSA-L,
AM1+ACVP-M(-0.65 to 7 bars) can make RSA-M,
AM1+ACVP-H(4 to 25 bars) can make RSA-L.

The pressure regulators RSA type can be supplied as RSA-L,RSA-M and RSA-H options set pressure and sealed in factory.

Working principle

The pressure regulators RSA series control the inlet pressure of main valve. They are opened when the pressure exceeds the set pressure on the control pilot, so relieving the inside pressure to protect.

When the pilot open. the inlet fluid pass to the top of the piston to open the main valve.

The pressure regulators close again, When the inlet pressure decreases below the set pressure on the pilot

Application

The pressure regulators RSA are designed to work with ammonia and other fluorinated refrigerants,to control evaporator pressure , condensing pressure, pressure in vessels or pressure in any portion of the system. keeping this one below of the set pressure of the pilot。
