AWP HRAB control valves
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.
