RSABL Differential Pressure Regulators & Electric Shut-off valve

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

Characteristics

• RSABL is a set make up of one AM3 and one differential regulation pilot ACVPP and one solenoid pilot AEVM-NC.
• The differential pressure regulators can be supplied as RSABLE,with extemal connection at(4) to hot gas inyection for wide opening the main Valve.

Operation

• The pressure regulators RSABL type,maintain the differential pressure between inlet and outlet of the main valve,modulating, is to say,opening and closing the valve，if this difference inlet and outlet pressure, rise or fall with regard to the set polnt.
• The main valves close again，When the differential pressure inlet/outlet decreases below the pressure setting of the ACVPP、 or the coil of solenoid pilot have been de-energized

Applications

The regulators RSABLare designed to work with ammonia and other fluorinated refrigerants,to defrost with the solenoid pilot enrgized ,and to maintain a differential of pressure between two points of the line,to avoid for ex. the backward step of condensed and hot gas.
