The two-position four-way solenoid valve is a zero-start straight electromagnetic slide valve. In the working system, the electromagnet receives the electric signal, which causes the valve core to reversing and changes the direction of the medium circulation. After the electric signal disappears, the valve core is automatically reset by the spring to achieve the purpose of automatic control, and has an electric device. The utility model has the advantages of simple structure, reliable action, convenient maintenance, good sealing performance, vibration resistance and long service life, and is particularly suitable for a workplace with poor environmental conditions such as steel, casting and sewage.
The two-position four-way solenoid valve can be installed at any position. When installing, P is the medium inlet, "A" and "B" are the medium outlets, and "O" is the discharge port. The hardware pipe thread is G1/2 (or can be changed to M20×1.5 according to user requirements). See the external dimension drawing. The pipe connection should not leak air. Before the pipe, dry the compressed air to blow the dust and dirt inside the pipe. And install a filter larger than 100 mesh in front of the valve.
The fault of the two-position four-way solenoid valve: there is no commutation of power supply; no power failure is reset; three types of leakage. Cause: The coil may burn out or the connection is not secure; the spool is stuck; the spring is damaged, the seal is broken, etc. Troubleshoot: replace the coil or reconnect; clean the valve plug, replace the spring, seal.
