RSAD Two-stage pressure regulating valve

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

 Characteristics

•  RSAD is a set make up of one AM3 and two regulation pilots ACVP-L for 0 to 10 bar, as standard option RSAD or with two ACVP-H for 4 to 25 bar，option RSAD-H. or finally with one solenoid pilot ACVP-L and other ACVP-H, version RSAD-LH.The pilots must be set to different pressures，and the pilot with below set pressure wiil be control with a solenoid pilot AEVM-NC or AEVM-NO by Order.
• The pressure regulators RSAD type can be supplied as RSADK options set pressure and sealed in factory

Operation

• The pressure regulators RSAD type，control the inlet pressure of the main valve，as two RSA regulators with two differents set pressure everyone，opening this one when the inlet pressure exceeds the pressure setting on the control pilot with lower set pressure，if the coil of the solenoid pilot have been energized (AEVM-NC)or de-energized(AEVM—NO optiorl).
• When the pilot in function open,the inet fluid pass to the top of piston,opening the main valve.

Applications

The regulators RSAD are designed to work with ammonia and other fluorinated refrigerants，to control of the defrost pressure pilot(B),control of condensation pressure，pilot(A). or control of evaporation pressure,with two possibilities acording to the pilot in service
