self-holding type solenoid valve
Self-holding type solenoid Valve is solenoid valve only moments power on to complete the valve switching action without electricity to keep the spool position. It has the advantage of saving energy, in particular in the occasion of using batteries as power supply, and may without to consider the temperature rise, thus the coil has long life, at high temperature, explosion-proof and other occasions have a higher security. Common are mechanical maintenance and permanent magnet to maintain, but also double-coil and single coil, single coil magnetic maintain structure is the most simple. It is based on changing the polarity of DC power to change the two states of corresponding valve switches. This solenoid valve coil external wiring is required to install a separate switch, and with intelligent instrument package will be very convenient. IC Card Pre-pay gas and water meters are equipped with solenoid valve are one key to success, in which the self-sustaining technology is an important factor in the success. the domestic self-sustaining solenoid Valve has become increasingly mature, our company has provided supports to a multi-smart factories.
