Description

These compact, heavy duty, pilot operated, iron alloy (ASTM A126 Class 

B) Outlet Pressure regulators are suitable for Ammonia, R-12, R-22, 

R-502 and other common refrigerants and fl uids approved for use in 

refrigerant valves. All A4 Regulators are pilot operated using upstream 

Purpose

Modulates fl ow of refrigerant gas or liquid to maintain a constant down-

stream pressure as set-for, despite fl uctuations in load. The regulator 

will gradually close when downstream pressure begins to rise above the 

setting and will gradually open when pressure begins to fall below the 

setting. The regulator cannot maintain set-for pressure if uncontrolled 

branch pipe lines feed into the main pipeline downstream of the A4AO 

Regulator. Typical uses are as follows:

Protect Compressor Motor from Overload (Hold-back): 

See capacity 

ratings in Condensed Catalog CC-11. Select at design parameters i.e., 

tons, evaporator temp./press and pressure drop.

Hot  Gas  Bypass  Capacity  Control: 

See  Bulletin  BYG-4,  Condensed 

Catalog CC-11.

Limit Refrigerant Pressure in a Liquid Line: 

Contact factory for selec-

tion assistance.

Prevent Deep Vacuum in Booster Suction: 

See capacity ratings Con-

densed Catalog CC-11 “Compressor Suction Loading”. For selections 

other than those shown, contact factory.

Prevent Pressure Rise in Suction Main: 

Select valve based on mass fl ow 

requirements. Valve Cv and pressure drop across regulator. Contact 

factory for proper selection assistance, if required.

Hot  Gas  Defrost  Control: 

Refer  to  Condensed  Catalog  CC-1  1  and 

Bulletin 90-10 for ratings and application information.

pressure for the opening force and requires a minimum 0.14 bar (2 psig) 

pressure drop to fully open.
These  valves  are  generally  ordered  with  close  coupled  strainer  to 

prevent entrance of foreign material into the valve and the rest of the 

system. (See current Bulletin 00-10 for strainer information.)
The fl uid temperature range for the A4 Series of Regulators is -45°C 

to 105°C (-50°F to 220°F).
