Refrigerating Specialties A4 Series Adaptomode Inlet Pressure Regulators

These compact, heavy duty, pilot operated, iron alloy (ASTM A126 Class B high strength semi-steel) Inlet Pressure Regulators are suitable for Ammonia, R-12, R-22, R-502 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 requires a minimum 0.14 bar (2 psi) pressure drop to fully open.

These valves are generally ordered with close coupled upstream strainer to prevent entrance of foreign material into the valve and the rest of the system.
