Introduction:
V20series electrical valve is used for opening and shutting down pipeline in the central air-conditioning system and the heating system, achieves the goal of controlling constant room temperature. The control valve drives by the unidirectional magnetic lag synchronous motor, the spring repositions. When the valve does not work is often in close condition, when needs to work, open the valve signal provides by thermostat, causes the motorized valve connect to the alternating current and work, opens the valve, the freezing water or the hot water enters the blower fan scroll, provides cold air and warm air for the room; When the room temperature achieves the thermostat’s set temperature, thermostat makes the motorized valve power off, the recoil check spring causes the valve close, thus interrupts the entering current water to blower fan scroll. By shutting down and opening of the valve, makes the room temperature maintain at the set temperature range. V20 series motorized valve may select and match auxiliary switch, applies to other control equipments; And may select different pipe connections to be suitable to the voltage, meets the different needs. V20 series motorized valve, operates nimbly, reliable and durable, low work noise, and can endure the high temperature environment which often appears in the hidden blower fan scroll.
