Product Description

DESCRIPTION
RSAB is made up of one main valve AM3 and one pilot valve. Different pilot valves can make different regulators:AM3+ACVP-L(O to 10 bars)can make RSAB,AM3+ACVP-H (4 to 25 bars) can make RSAB-H.This regulator also combined with one solenoid pilot AEVM-NC. When the coil is energized, the main valve is wide open.

The pressure of RSAB series can be set based on orders in the factory before delivery.
Operation
Same as RSA regulators. the pressure regulators RSAB, control the inlet pressure of the main valve. Regulators open when the pressure exceeds the set pressure on the control pilot. But if the coil of the solenoid pilot have been energized the main valve will be wide open,with the independence of the inlet pressure.

When the pilot open,or the solenoid is energized,the inlet fluid pass to the top of the piston to open the main valve.

The main valves close again, when the inlet pressure decreases below the set pressure of the pilot,or the coil of solenoid pilot have been de-energized.

APPLICATION
The regulators RSAB are designed to work with ammonia and other fluorinated refrigerants to defrost and temperature control, with wide-open possibility for maximum cooling.
