The 2/2-way solenoid valve is the most common type of valve used to control fluid on/off by energizing or de-energizing the coil. It is available in normally closed (NC) and normally open (NO) types. According to their mode of operation, solenoid valves can be classified as:

  • Direct-acting solenoid valve: Has a simple structure and fast response (10–50 ms), suitable for low pressure and small flow.
  • Pilot-operated solenoid valve: Uses the pressure of the media to assist operation, suitable for high-pressure and large-flow applications (50–300 ms).

Directional control valve (typically 3/2-way or 5/2-way) is used to change the direction of the fluid flow. They usually adopt a spool or rotary structure and have a switching time of 20–500 ms. Selection of media, flow pressure, response time, and other factors will affect the valve's performance. Please contact us if you are having trouble choosing the solenoid valve models.

Yes. The solenoid valve can be easily cleaned by unscrewing the four bolts.

80% of the solenoid valve is made of durable metal (e.g., brass, stainless steel, cast aluminum, and cast iron), so you only need to change the rubber seal and the coil, which are prone to wear.

It is recommended to choose carefully based on actual site conditions and pressure/flow requirements.

  • Direct-acting solenoid valve: Has a simple structure and low maintenance, but has higher impurities. It is suitable for a high-response environment with a pressure of 1.0MPa or lower.
  • Pilot-operated solenoid valve: Has a double-layer structure, which is suitable for higher pressure (up to 1.6MPa) and larger flow.
