A2 Pressure Regulator Clark Johnson Co

Refrigerant Pressure Regulators

 

Commercial Pressure Regulator - Flo-Con A2

parker refrigeration Clark Johnson Co

The A2B products are compact pressure regulators that maintain upstream or downstream despite fluctuations in load.

  Product Overview

     Specification

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.
