A Brief Introduction Of Solenoid Valve

1.Description
CE1S series solenoid valves are a kind of automatic control device used in various industrial processes. They open and close automatically according to electric-controlled signals in the control of liquid media, air and gas.
2. Features
These solenoid valves feature:
(1) Wide applications, suitable for various kinds of gases and liquids.
(2) State-of Arts design and compact construction.
(3) Reliable service and high sensitivity. The solenoid valves can work normally even when the working differential pressure is close to zero.
3. Construction
The solenoid valves work on the principle of kick-directed step action. Each valve is composed of a valve body, a valve cover, a valve core and a coil. When the coil is charged, the electro-magnetic force thus produced will attract the armature, causing the pilot valve to open. Then, the pressure built in the back cavity of the valve core will be released via the pilot valve, thus building a differential pressure between the main cavity and the back cavity of the valve core, causing the valve to open.
When the power source of the coil is turned off, the armature will cause the pilot valve to close under the force of the restoration spring. Then the differential pressure between the main cavity and the back cavity of the core will reach balance and the valve will thus be closed under the force of the spring. A highly sensitive device, the solenoid valves can work with a differential pressure that is close to zero and they can therefore be used to replace the direct operation solenoid valves.
