Coil voltages: solenoid valves air valves 12V Direct Current The solenoid valves make from materials metal, which is full of durability, rust-proof and resistant Operating model: direct acting; flows model: unidirectional It has been developed for automatic control of liquids and and is ideal for electropneumatic power control Service media: air,, liquid, waterThis solenoid valves has a wide ranges of applications and can be widely used in mechanical engineering, automation devices, hydraulic systems, and so on Valves type normally 2 way solenoid valves with two positions, direction-dependent and fast The solenoid valves is usually closed turn on when power flows and off when none electricity flows The solenoid valves is lightweight and compact and easy to transport and store Reversing is sensitive and fast, good sealing and stable
