1. Introduction
This manual provides essential information for the safe and efficient installation, operation, and maintenance of your WVCLTVJA 160bar 16MPa 2-Way Nitrogen High Pressure Solenoid Valve. Please read this manual thoroughly before attempting to install or operate the valve. Retain this manual for future reference.
2. Safety Information
WARNING: Failure to follow these safety instructions may result in serious injury, property damage, or death.
- Always ensure that the system pressure is fully relieved and the electrical power supply is disconnected before installation, maintenance, or troubleshooting.
- Installation and maintenance should only be performed by qualified personnel familiar with high-pressure pneumatic systems and electrical wiring.
- Verify that the valve's specifications (pressure, voltage, medium) match your application requirements.
- Use appropriate personal protective equipment (PPE) such as safety glasses and gloves.
- Do not exceed the maximum rated pressure or temperature.
- Ensure proper grounding for electrical connections.
3. Product Overview
The WVCLTVJA 160bar 16MPa 2-Way Nitrogen High Pressure Solenoid Valve is designed for controlling the flow of nitrogen in high-pressure applications. This is a normally closed valve, meaning it remains closed when de-energized and opens when electrical power is applied to the coil. It features a durable SS304 stainless steel body and a 1mm orifice for precise control.

5. Setup and Installation
5.1 Pre-Installation Checks
- Inspect the valve for any signs of damage during shipping.
- Confirm that the valve's specifications (pressure, temperature, voltage, port size) are compatible with your system.
- Ensure the nitrogen supply is clean and free of particulate matter to prevent valve malfunction.
5.2 Mounting
- Mount the valve in a location that is easily accessible for maintenance and inspection.
- Ensure the valve is installed with the flow direction arrow (if present) matching the system's flow.
- The valve can typically be mounted in any orientation, but vertical mounting with the coil upwards is often preferred to prevent accumulation of debris.
5.3 Pneumatic Connections
- Connect the high-pressure nitrogen lines to the valve's 1/8 Inch NPT ports.
- Use appropriate thread sealant (e.g., PTFE tape) on all threaded connections to ensure a leak-free seal.
- Tighten connections securely but do not overtighten, which can damage the valve body or threads.
5.4 Electrical Connections
- DANGER: Disconnect all power before making electrical connections.
- Connect the AC120V power supply to the solenoid coil terminals.
- Ensure proper polarity if applicable (though AC typically does not have strict polarity).
- Verify that all electrical connections are secure and insulated to prevent short circuits or electrical hazards.
- Ensure the electrical circuit is protected by an appropriate fuse or circuit breaker.
6. Operating Instructions
This is a normally closed (NC) solenoid valve. Its operation is as follows:
- De-energized State: When no electrical power is supplied to the coil, the valve remains closed, preventing the flow of nitrogen.
- Energized State: When AC120V electrical power is supplied to the coil, the solenoid activates, opening the valve and allowing nitrogen to flow through.
6.1 Initial Startup
- After installation, slowly introduce nitrogen pressure into the system.
- Check all connections for leaks using a suitable leak detection solution.
- Apply power to the solenoid coil to open the valve and verify proper flow.
- Remove power to close the valve and confirm the cessation of flow.
7. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of the solenoid valve.
7.1 Routine Checks
- Periodically inspect the valve for external leaks, especially around connections.
- Check electrical connections for tightness and signs of corrosion or damage.
- Listen for unusual noises during operation, which may indicate internal issues.
7.2 Cleaning
- Ensure the nitrogen supply is clean. If the system is prone to contamination, consider installing an inline filter upstream of the valve.
- If the valve becomes sluggish or fails to operate, it may require internal cleaning. This should only be performed by qualified personnel after depressurizing the system and disconnecting power.
7.3 Storage
- Store the valve in a clean, dry environment, away from direct sunlight and extreme temperatures.
- Keep port caps on (if provided) to prevent foreign matter from entering the valve.
8. Troubleshooting
Before troubleshooting, ensure all safety precautions are followed, including depressurizing the system and disconnecting electrical power.
| Problem | Possible Cause | Solution |
|---|---|---|
| Valve does not open when energized | No power to coil Incorrect voltage Damaged coil Obstruction in valve Excessive pressure differential | Check electrical connections and power supply Verify correct AC120V supply Replace coil Clean valve internals Ensure pressure is within operating range |
| Valve does not close when de-energized | Coil remains energized Debris preventing closure Damaged internal components | Check electrical control circuit Clean valve internals Replace valve |
| External leakage | Loose connections Damaged seals/gaskets | Tighten connections (do not overtighten) Replace seals/gaskets (professional service recommended) |
| Reduced flow | Partial obstruction Insufficient inlet pressure | Clean valve internals Check system pressure supply |
