To ensure the safe and effective operation of your Squibb Taylor A120-45A 12 Volt Nurse Tank Fail-Safe Valve, regular testing is essential. The manufacturer recommends testing the valve at least once a month. During field application periods, it's advisable to test it daily. Here’s how to test your valve:
Opening Operation Test:
- Move the lever to the right until it stops, then release it.
- The plunger on the Manual Release should retract into the Release Housing, allowing the lever to move.
- Once the lever moves past the plunger, it should pop out, preventing it from returning to the Closed Position.
Closing Operation Test:
- Pull on the Carabiner on the end of the cable until the plunger retracts, enabling the lever to move to the Closed Position.
- Release the cable and check the lever's position to confirm the valve is closed.
- Verify that the plunger has popped back out.
Additional Testing and Best Practices:
- Always open the internal valve before opening any other valves in the line.
- Move the lever to the half-open (rapid equalization) position to equalize pressure before fully opening the valve.
- Open other line valves slowly to avoid sudden surges that could affect the excess flow valve.
- If the excess flow valve closes, follow the manual's instructions to reopen it.
Maintenance and Inspection:
- Regularly inspect the valve's actuation to ensure smooth, leak-free operation.
- Check for tight closure of the valve seal and address any leakage immediately.
- Inspect and maintain all operating controls to ensure they function correctly.
By adhering to these testing and maintenance procedures, you can help ensure the Squibb Taylor A120-45A 12 Volt Nurse Tank Fail-Safe Valve operates safely and reliably for your Anhydrous Ammonia applications.
