RSAB Pressure regulation&solenoid shutoff valve

Technical parameters

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

Characteristics

• RSAB iS a set make up of one AM3 and one regulation pilot ACVP-L for 0 to 10 bar, as standard option RSAB or with one ACVP-H for 4 to 25 bar, option RSAB-H,and one solenoid pilot AEVM-NC, that when its coll is energized , the main valve is wide open.
• The pressure regulators RSAB type can be supplied as RSAB-L & RSAB-H options set pressure and sealed in factory

Operation

• The pressure regulatots RSAB type. control the inlet pressure ofmain valve. as the RSA regulators. opening this one when thepressure exceeds the pressure setting on the control pilot. but if the coil of the solenoid pilot have been energized the main valve will be wide open.with independence of the inlet pressure.
• When the pilot open，or the solenoid is energized，the inlet fluid pass to the top of piston,opening the main valve.
• The main valves close again，when the inlet pressure decreases below the pressure setting of the pilot, or the coil of solenoid pilot have been de-energized

Applications

The regulators RSAB are designed to wotk with ammonia and other fluorinated refrigerants， to defrosl and temperature control，with wide open possibility for maximum cooling
