Two four-way solenoid valve installation and maintenance

Two four-way solenoid valve overview: Two four-way solenoid valve is a zero-start direct-acting solenoid valve. In the working system, the electromagnet receives the electric signal, commutates the valve spool to change the direction of the medium flow, and after the electric signal disappears, the valve spool is automatically reset by the spring to achieve the purpose of automatic control with a manual device. It is simple in structure, reliable action, easy maintenance, good sealing performance, stain resistance, vibration resistance, long life and other advantages. Two four-way solenoid valve is particularly suitable for steel, casting, sewage and other harsh environmental conditions of the workplace. Two four-way solenoid valve installation and maintenance: 1, solenoid valve can be installed anywhere. 2, when installed, P for the media imports, "A", "B" for the media outlet, "O" for the discharge port. 3, to take over the thread for the G1 / 2 (or by advocacy requirements to M20 × 1.5) See the exterior dimensions. 4, pipe connections shall not leak, according to the pipe before the first need to use dry compressed air to the pipe dust and dirt blowing, and to install more than 100 before the valve filter. 5, the valve fault: there is no power commutation; power is not reset; leak three. Failure reasons: the coil may burn or the connection is not solid; spool stuck; spring damage, seal breakage and so on. Troubleshooting: Change coil or reconnect; clean valve plug, replace spring or seal. Note: Two four-way solenoid valve is installed on the pneumatic and hydraulic actuators supporting the use of.
