Data for 275V
The 275V is a 1/2" subplate style, 2 position, friction position, differential pilot operated valve. The internal spool is shifted by reducing the pressure in either endcap. Once the the internal pressure is vented, the spool will shift and remain in the shifted position. This valve is not supplied with the standard button bleeder valves. The response time of the valve shifting is dependent upon the distance from the button to the valve as well as the hose diameter used (smaller diameters allow faster response times). Valve must be used with a subplate style connection. See the dedicated subplate section. Button bleeder cannot be routed through the subplate.
Details
Pressure: 15 to 250 psi on the main body of the valve.
Vacuum: Button bleeder valves cannot be used for vacuum service.
Temperature: -20°F to 250°F. Caution: If it is possible that the ambient temperature may fall below freezing, the medium must be moisture free to prevent internal damage or unpredictable behavior.
Mounting: The spool is friction positioned so the valve must be mounted with the spool in a horizontal orientation.
O-Rings: Viton.
Materials: Black anodized 356-T6 aluminum body, hard anodized aluminum spool, A380 aluminum end caps, composite gaskets, steel fasteners.
Flow: 215 SCFM, 5.0 Cv
Repair Kit: ERKV-4-3 & two ECG48-3 gaskets.
Subplate: 1/2" without pilots.
3-Way: While this valve is basically 4-way, it can be used for 3-way service by plugging the unused port 2 or 4, port 1 must remain pressurized to create the differential pressure required to shift the spool.
Fluid Media: Soft seal models are made for air, vacuum, and gases compatible with component materials. They should not be used with liquids.

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.
