Latching solenoid valves, also referred to as bi-stable solenoid valves feature a permanent magnet attached to the armature, when energised with short 250msec 6 volt pulse the armature is forced into either open or closed state depending on the signal polarity. They provide effective on/off control of water services ranging from 0.2 – 10bar where a constant supply of electrical power is either not appropriate or available.
Our extensive range can be supplied with a latching operating system without any change to solenoid valve external features. The compact design and robust construction ensures a long service life, which has been tested up to 50,000 operations on hot and cold water supplies up to 85°C.
Latching solenoid valves are ideally suited for applications using battery or low power electronic power supplies, these include commercial urinal and automatic faucets and sprinkler systems.
