1. Introduction
This manual provides essential information for the safe and efficient installation, operation, and maintenance of the ASCO EVX8316G382MB17596 Solenoid Valve. Please read this manual thoroughly before attempting to install or operate the valve. Retain this manual for future reference.
2. Safety Information
Always observe the following safety precautions to prevent personal injury or damage to the equipment:
- Electrical Hazard: Ensure power is disconnected before installation, maintenance, or troubleshooting. Only qualified personnel should perform electrical connections.
- Pressure Hazard: Depressurize the system completely before working on the valve. Sudden release of pressure can cause serious injury.
- Temperature Hazard: The valve body and coil may become hot during operation. Allow adequate cooling time before handling.
- Chemical Compatibility: Verify that the valve materials are compatible with the media being controlled to prevent corrosion or failure.
- Proper Installation: Install the valve according to local codes and regulations, and ensure all connections are secure to prevent leaks.
3. Product Overview
The ASCO EVX8316G382MB17596 is a 2-way, normally closed solenoid valve designed for general purpose applications. It operates on 24VDC power, consuming 1.4W, and features a 3/8-inch pipe connection. This valve is suitable for controlling the flow of various fluids and gases.

4. Setup and Installation
- Inspect the Valve: Before installation, visually inspect the valve for any damage that may have occurred during shipping.
- Prepare the System: Ensure the system is depressurized and drained. Clean the pipe lines to remove any debris that could interfere with valve operation.
- Mounting: Mount the valve in the correct orientation as indicated by flow arrows on the valve body. The valve can typically be mounted in any position without affecting operation, but vertical mounting with the coil upwards is often preferred for optimal performance and longevity.
- Pipe Connections: Connect the valve to the piping using appropriate thread sealant (e.g., PTFE tape) on the male pipe threads. Do not overtighten, as this can damage the valve body. The valve features 3/8-inch pipe connections.
- Electrical Connections: Connect the 24VDC power supply to the solenoid coil terminals. Ensure correct polarity if specified on the coil or in accompanying documentation. The valve consumes 1.4W.
- Test for Leaks: Slowly pressurize the system and check all connections for leaks.
- Functional Test: Energize and de-energize the coil to verify proper valve operation.
5. Operating Instructions
The ASCO EVX8316G382MB17596 is a normally closed valve, meaning it remains closed when the coil is de-energized and opens when the coil is energized.
- Energizing the Coil: Apply 24VDC power to the coil terminals. The valve will open, allowing fluid or gas to flow through.
- De-energizing the Coil: Remove the 24VDC power from the coil terminals. The valve will close, stopping the flow.
- Continuous Operation: The valve is designed for continuous duty within its specified temperature and pressure ranges.
6. Maintenance
Regular maintenance ensures optimal performance and extends the life of your solenoid valve.
- Periodic Inspection: Regularly inspect the valve for external leaks, corrosion, or damage to the coil.
- Cleaning: If the valve is operating in a dirty environment, periodically clean the exterior of the valve and coil to prevent heat buildup.
- Internal Cleaning (if necessary): If the valve exhibits sluggish operation or leakage, internal components may need cleaning or replacement. This should only be performed by qualified personnel after depressurizing and draining the system. Refer to ASCO service instructions for specific procedures.
- Replacement Parts: Use only genuine ASCO replacement parts for any repairs.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Valve does not open when energized | No power to coil; Incorrect voltage; Damaged coil; Obstruction in valve | Check power supply and connections; Verify correct 24VDC; Replace coil; Clean valve internals |
| Valve does not close when de-energized | Debris preventing closure; Worn internal parts; Residual magnetism | Clean valve internals; Replace worn parts; Consult ASCO support |
| External leakage | Loose pipe connections; Damaged seals/gaskets; Cracked valve body | Tighten connections; Replace seals/gaskets; Replace valve |
| Excessive noise or vibration | Incorrect mounting; Pressure fluctuations; Debris | Verify mounting; Check system pressure; Clean valve |
