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.

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.

If you are in a low-temperature region, it is recommended to choose the anti-freeze solenoid valve (down to -20°C). The valve body’s drainage design effectively prevents freezing, expansion, and cracking.

Yes. The valve body is available in 316L stainless steel.

Yes. We recommend solenoid valves made from 316L stainless steel with EPDM or PTFE sealing materials. These materials are non-toxic, corrosion-resistant, and pollution-free, making them suitable for purified and drinking water systems.

Yes, this valve is suitable for neutral liquids such as water, weak acids, weak alkalis. However, for strongly corrosive media, it is recommended to choose solenoid valve with PVDF or CPVC body.

Yes. The temperature resistance of the nylon solenoid valve is from -10°C to 80°C. For applications exceeding this range, we recommend choosing a valve made with high-temperature plastics (such as PPS) or metal.

Yes. The KSD Series solenoid valve body is compact and supports quick plug-in connections for tight spaces.

No problem. The voltage can be customized (DC12–48V / AC24–240V). Wide-voltage dual-use (DC/AC) versions are also available.

Yes. The standard protection rating for the valve is IP65, and it can be upgraded to IP68 for outdoor, marine, or washdown environments, such as construction machinery or marine systems.

We recommended quick push-in fittings with nickel-plated brass bodies and NBR seals. These fittings support one-handed operation, with over 100,000 cycles, and provide cost-effective durability for high-frequency compressed air systems.

It is recommended to choose IP67-rated oil-resistant fittings made of stainless steel bodies and FKM seals, with threaded locking designs for secure sealing under vibration.

Select anti-static fittings with PPS conductive materials and IP65-rated sealing. It has a surface resistance of <10⁶ Ω, which prevents dust adsorption, ideal for chip (semiconductor) packaging and PCB assembly equipment.

We recommend the AC series FRL Unit, which combines air filtration, regulation, and lubrication functions with high cost-effectiveness.

We recommend using the AW-D series automatic drainage type, which has an electronic drain valve (EDV) to discharge accumulated water automatically, keeping pneumatic systems dry and reliable.

Replace the filter every 6–12 months in normal environments, or every 3–6 months under heavy dust or humidity.

The standard operating pressure range is 0.1–1.0 MPa. However, a high-pressure version can be customized up to 1.6 MPa.
