Refrigerating Specialties A9 Series Pressure Regulators

A9 outlet pressure regulators utilize a compact design unique to the Refrigerating Specialties line of regulators, and are applied most typically as hot gas bypass or receiver pressure control valves. Four port sizes ranging from 3/8" (9mm) through 1-1/8" (28mm) are available. Utilizing a pilot operated design for stable control of set point, the A9E is typically used as a hot gas bypass regulator. The A9E regulator, when used in a hot gas bypass application, is externally equalized to suction pressure, or the pressure being controlled. Through years of reliable performance, it has become a standard on a variety of OEM equipment where precise suction pressure control is required for stable system operation. The A9, an internally equalized regulator which senses and controls immediate downstream pressure, is typically applied as a receiver pressure control valve for those systems using regulators for condenser pressure control on air cooled condensers.
