Solenoid Valves

Solenoid valve is the core component of fluid control systems commonly used across industrial automation, medical equipment, petrochemical industries, etc., mainly to control the on/off, flow, and direction of liquids and gases. Based on function, solenoid valves are classified into two types: 2/2-way solenoid valves and directional control valves.

SENYA offers more than 40 solenoid valve models, covering media temperatures from −40°C to 220°C and operating pressures from 0 to 50 bar. In addition to our standard models, SENYA offers flexible customization options to match your specific project requirements.

Customization Options
  • Waterproofing: IP ratings (IP65/IP67/IP68) available for most models (excluding the USF series)
  • Seal Materials: FKM, EDPM, HNBR, FFKM, PTFE for compatibility with different media
  • Body Materialss: Brass, stainless steel, or engineering plastics
  • Manual Override: Optional manual knob allows the valve to be forced open without power
  • Mounting Method: Bottom mounting, horizontal mounting, flexible mounting, etc. (customizable)
  • Valve Manifold Design: Customize design available upon request

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.

2S series solenoid valve can be used with sulfuric acid and hydrochloric acid solutions at concentrations below 10%. For higher concentrations of sulfuric acid, such as 30%, we also offer customized solenoid valves for your selection.

Yes. 2S series valve body is available with 316L stainless steel material. If you need to handle higher concentrations of sulfuric acid, such as 30%, we can also provide customized solenoid valve solutions.

Yes. The USF series can withstand a long-term, high temperature up to 180°C. The spring force of the valve plunger ensures smooth sealing under high pressure, and the PTFE sealing improves high-temperature resistance. The valve lifecycle depends on operating conditions, pressure, and cycling frequency.

We offer explosion-proof solenoid valves with Ex mb II T4 Gb Explosion Proof Certification. Voltage configurations can be customized to meet your requirements.
