GEA AWP HRAB control valves

AWP control valves with metal bellows are suitable for use in refrigerant circuits in industrial refrigeration systems.

AWP control valves with metal bellows are suitable for use in refrigerant circuits in industrial refrigeration systems. They can be actuated with a hand wheel and are closed by turning clockwise and opened by turning counterclockwise. These are control and shut-off valves. At maximum lift, the control cone releases the control nozzle. The diameter of the control nozzle corresponds to the nominal width. The valves are equipped with a back seat (flat sealing ring R). When the valve is fully open, the sealing elements (O-rings A, B, PTFE rings) on the spindle can be safely replaced by unscrewing the screw bushing.
