Data for 712V

The 712V is a 1/2" NPTF side ported, 2 position, spring return, solenoid operated valve with manual lever assist. The internal spool is shifted either by 50 to 160 psi internal pilot air derived from pressure in port 1 when the solenoid is energized or with the manual lever. 50 to 160 psi must be maintained on port 1 to keep the spool shifted while the coil is energized. The spool is spring returned when the solenoid is de-energized. See additional information on solenoid valve operation. Hand lever/Solenoid can be locked out in position 'C' using a LO23 lock-out hasp or a 7LJKAP Master lock.

Details

Pressure: 50 to 160 psi on the main body of the valve when solenoid is internally piloted.
Vacuum: The valve cannot be vacuum operated when the solenoid is internally piloted.
Temperature: -20°F to 120°F ambient. 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 valve can be mounted in any orientation.
O-Rings: Buna-N.
Solenoid Seat: Buna-N.
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 & RKPSV-1.
3-Way or 5-Way: This valve is basically 4-way, it must be configured for external pilot (Option 'Z') for 5-way service by using ports 2 or 4 as an inlet, or 3-way service by plugging the unused port 2 or 4.
Fluid Media: Soft seal models are made for air, vacuum, and gases compatible with component materials. They should not be used with liquids.

"Classic" Operator & Coil - Standard

The "Classic" solenoid operators sturdy and tough construction with a 1/2" NPT conduit connection. The stem exhaust is tapped 10-32. Voltage must be specified when ordering valves that use this operator. If no voltage is specified, then 120/60 is provided. Other voltages not shown below are available. Coil can be rotated in any direction on operator stem when space is available. Caution must be used when rotating coil so not to untighten the stem from the adaptor block. Standard leads are 18", longer leads available on request. When connecting to an electrical source either black wire can be connected to hot (+) and the other connected to neutral (-).

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.
