Two-position three-way direct-acting solenoid valve is divided into normally closed type, normally open type, reversing type, universal type, automatic exhaust type, etc. It has three connection ports. The normally closed type has one inlet, one outlet, and one discharge outlet. When the solenoid coil is powered off, the spring acts on the moving iron core (with seals at both ends) to close the inlet of the main valve. The inlet and outlet do not circulate, and the outlet and the discharge port are connected. When the coil is energized, under the action of electromagnetic force and medium pressure, Overcoming the spring force, the moving iron core moves upward to the static iron core. At this time, the inlet and the outlet are connected, and the discharge port is closed.

The two-position three-way direct-acting solenoid valve is small in size and flexible in design. For example, the three ports of the SLV series are two distributed on the valve body, and the other is on the top of the magnetic isolation tube; another design, such as the SLT series, three Both inlets and outlets are in the valve body. At this time, the flow diameter is small, and the direct-acting design can be used. The flow diameter is large. As long as the coil power of the direct-acting type is increased, the pilot-type design coil power can be smaller. The functions are basically the same, all of which provide automatic control or drive to the medium, large valves, cylinders, etc.
Solenoid valve application is based on various media, temperature, pressure, flow and other parameters, choose the material of the main valve, usually copper, stainless steel, etc., sealing materials include NBR, VITON, EPDM, etc., and the corresponding connection, flow diameter From DN 0.5 ~ 15 mm, larger can reach DN50.
