General - Installation & Maintenance

Valves should be installed with reasonable accessibility for service. Exercise care in keeping tubing lengths to a minimum. Plumbing should be free of contamination. Pipe joint compound should be used sparingly applied only to the thread, never the valve body. Over tightening of pipe threads can fracture the joint causing leaks or failure. Protect the valve from exposure to extreme temperatures, dirt and moisture to maximize life.

General - Lubrication, Standard

All valves are pre-lubricated at the factory using Magnalube-G Teflon based all purpose grease. Valves are suitable for, and perform best in a non-lube service. For long life, use an air line filter/lubricator installed no further than 10-ft. from the valve. The filter should be rated 25 pm or finer. Use a good grade of petroleum base lubricating oil no heavier than SAE 10W. DO NOT OVER-LUBRICATE. This could cause the spool to stick. CAUTION! Do not use questionable fluids in air line lubricators. Do not use petroleum oil with detergent additives. Detergents, volatile or aromatic fluids may swell rubber seals in valves and cylinders. Never use cooking or vegetable oil as a lubricant. When cleaning AAA valves after extended service, lubricate the valve spool with AAA high film strength grease, or, use O-ring grease which is usually available from supply houses which sell O-rings. Magnalube-G is included in all valve repair kits for proper valve maintenance. If an additional amount of Magnalube-G grease is required, a 0.75 ounce tube is available under part number VGK-3. Never use any kind of oil, cup grease, or automobile chassis lubricant.

The shelf life of Magnalube-G regularly lasts for 10+ year intervals in closed packaging due to the extremely long operating life of the Elastomer-PTFE gelling agent and premium parafiinic mineral base oil. If the valve is stored for over 2 years, then a small reapplication of grease is suggested.
