Description

The A2B products are compact pressure regulators that maintain upstream or downstream despite fluctuations in load. 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. Market: • Industrial Refrigeration • Commercial Refrigeration Features and Benefits: • Compact Direct Diaphragm Operated • 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).
