Service valves with lifting stem, electrically actuated, available with various connections. Stem sealing provided by threaded bush.
HRS MAV
AWP service valves are designed to attach additional devices such as manometers to heating and refrigeration systems. Therefore they 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.
