A2B-series Parker - Refrigerating Specialties A2B Inlet Pressure Regulators

Parker's A2 series of compact pressure regulators help reduce system cost and complexity by utilizing a compact housing and direct operation. These valves are ideal for applications where a larger pilot operating valve is too costly or too large. The regulators can be used with ammonia and certain other refrigerants, oil, and other approved fluids. The regulators are ideal for use in systems where a small inlet or outlet pressure regulator is needed and can also be used as a remote pilot for larger control valves that are located in difficult to service areas.

Features and Benefits:

• Compact Direct Diaphragm Operated
• Design Pressure (MRP): 27.6 bar (400 PSIG)
• Furnished with Flanged Connections: FPT, SW, WN or ODS
• Available with Close Coupled Strainer
• Stainless Steel Diaphragm
• Easily removed for service

Application:

• May be used as a remote pilot for larger valves.
• Modulates flow of refrigerant gas or liquid to maintain constant upstream (or inlet) pressure as set-for, despite load fluctuations. The fluid temperature range for the A2 Series of Regulators is -45°C to 105°C (-50°F to 220°F).
