GEA AWP HRS service valves
AWP service valves are suitable for use in refrigerant circuits for industrial refrigeration systems.
AWP service valves are suitable for use in refrigerant circuits for industrial refrigeration systems. AWP service valves are operated using a handwheel or a ratchet. They are closed by turning clockwise and opened by turning counterclockwise. The valves are equipped with a back seat. When the valve is fully open, the screw bushing and the seal can be replaced.
