Service valves with a pointed regulating cone for fine regulation of the medium flow, electrically actuated, available with various connections. Stem sealing provided by threaded bush.
HRSN MAV
AWP needle valves are equipped with a regulating cone to shut-off and regulate liquid and gaseous mediums. They are designed for installation in industrial heating and refrigeration systems and are available with various types of connections. They are operated by an electric actuator which is connected to the stem. To close the valve the actuator moves the stem clockwise which lowers the valve disc onto the valve seat. To open it the actuator moves the stem counter-clockwise which lifts the valve disc. The stem sealing is provided by a threaded bush.
