A switch solenoid valve is an electromechanical device used to control the flow of liquids or gases in various industrial, commercial, and residential applications. It operates by using an electric current to generate a magnetic field, which moves a plunger to open or close the valve. This allows for precise control, automation, and remote operation of fluid systems, making it essential in processes requiring reliability and efficiency.
Our switch solenoid valves are designed with cutting-edge technology to ensure top performance, durability, and safety. They are ideal for applications in water systems, HVAC, medical equipment, automotive industries, and more. Below are some standout features:

Switch solenoid valves are versatile and used across multiple industries. Common applications include:
Here are some common questions and detailed answers about switch solenoid valves to assist in your decision-making process.
What is the difference between normally closed and normally open solenoid valves?
Normally closed (NC) valves remain shut when de-energized and open when power is applied. Normally open (NO) valves are open when de-energized and close when powered. Choose NC for safety in fail-close applications, and NO for fail-open scenarios.
How do I select the right orifice size for my application?
The orifice size should match your flow rate requirements. Larger orifices allow higher flow but may require more power. Calculate based on the flow coefficient (Cv) and system pressure to ensure optimal performance without leakage or pressure drop.
What materials are best for corrosive fluids?
For corrosive media, use valves with bodies made of stainless steel or plastic (like PTFE), and seals from FKM (Viton) or EPDM. Always check chemical compatibility charts to avoid degradation and ensure longevity.
Can solenoid valves handle high temperatures?
Yes, high-temperature models are available with specialized materials such as high-grade seals and coils capable of operating up to 180°C. Standard valves typically range from -10°C to 120°C.
Why is my solenoid valve not opening or closing properly?
Common issues include power supply problems (low voltage), clogged orifice, damaged coil, or incorrect installation. Check electrical connections, clean the valve, and ensure it meets the system's pressure and flow requirements.
What maintenance is required for solenoid valves?
Regular inspection for leaks, cleaning of filters and orifices, and testing the coil resistance. For harsh environments, periodic replacement of seals may be necessary. Most valves are designed for low maintenance but follow manufacturer guidelines.
Are these valves suitable for use with gases and liquids?
Yes, but ensure the valve is rated for the specific medium. Some valves are optimized for liquids, while others handle gases. Differences in viscosity and pressure might affect performance, so select a model designed for your application.
What does the IP rating mean for solenoid valves?
IP (Ingress Protection) rating indicates resistance to dust and water. For example, IP65 is dust-tight and protected against water jets, making it suitable for outdoor or wet environments. Higher ratings like IP68 allow submersion.
Can I install the valve in any orientation?
Most solenoid valves can be installed vertically or horizontally, but always check the manual. Incorrect orientation might affect performance, especially for gravity-dependent applications. Ensure the coil is upright to prevent moisture accumulation.
Do you offer custom solenoid valve solutions?
Yes, we provide customization options for voltage, materials, orifice size, and connections to meet specific requirements. Contact our support team with your application details for tailored solutions.
