RSAS Elecromagnetic closure of pressure regulating valve

Technical parameters

• Nominal pressure: 2.8MPa
• Applicable temperature:-50℃ ~+120°c
• Test pressure:4.2MPa
• Applicable medium: ammonia, fluorine, propane,etc.

Characteristics

• RSAS is a set make up of one AM3 and one regulation pilot ACVP-L for 0 to 10 bar，as standard option RSAS or with one ACVP-H for 4 to 25 bar，option RSAS-H.and one solenold pilot AEVM-NC that deacivates the ACVP when is coil is de-energized, dosing of this way the main valve
• The pressure regulators RSAS type can be supplied as RSAS-L & RSAS-H options set pressure and sealed in factory,and with the solenoid AEVM-NO type. by order.

Operation

• The pressure regulators RSAS type，control the inlet pressure of main valve, as the RSA regulators，opening this one When the pressure exceeds the pressure setting on the control pilot，but only if the coil of the solenoid pilot have been energized.
• When the pilot open，the inlet fluid pass to the top of piston opening the main valve.
• The pressure regulators dose again , when the inlet pressure decreases below the pressure setting on the pilot,or the coil of solenoid pilot have been de-energized.

Applications

The pressure regulators RSAS are designed to work with ammonia and other fluorinated refrigerants , to control temperature， opening the valve or defrost, dosing the pass of fluid through the main valVe
