Refrigerating Specialties A4AM Electronically Compensated Pressure Regulator

These heavy duty, pilot operated, iron alloy (ASTM A126 Class B) pressure regulators are suitable for R-717, R-22, R502 and other common refrigerants and fluids approved for use in refrigeration systems. All A4 Regulators are pilot operated using upstream pressure for the opening force and require a minimum 2psi (0.14bar)pressure drop to fully open. These valves are generally ordered with a close coupled upstream strainer to prevent the entrance of foreign material into the valve and the rest of the system. The fluid temperature range for the A4 Series of Regulators is -50°F to 220°F (-45°C to 105°C).
