On/off relay valve is used to activate water coolant for handpieces or automatic cuspidor rinse. Water relay valves are designed to prevent retraction of water.
If handpiece water fails to shut off, then you need to replace the water on/off relay valve.
Product Details:
- Activated by an on/off toggle.
- Attaches to 1/8" tubing.
Installation Instructions (PDF):
- Turn off main supply of air and water.
- Install appropriate sized barbs with washers.
- Apply liquid soap to tubing and slip sleeve clamps over tubings (approx. 3/8” from end) ensuring the interior bevel faces the barb.
- Slip tubing over barbs and lock by sliding sleeve clamps over tubing portion on the barb with a pliers or sleeve tool. Dipping the end of the tubing in hot water will make it easier to slip over the barbs.
NOTE: For replacement o-rings see #18-OR-001 and #18-OR-002.
