Data for 697V

The 697V is a 1/4" NPTF side ported semi-subplated, NAMUR style, 2 position, double solenoid operated valve with a twist locking solenoid override and with a side exhaust nut on the solenoid stem. The spool is retained in either position until shifted. The spool is shifted by 25 to 150 psi internal pilot air derived from pressure in port 1 when the solenoid is energized. The spool is returned when the solenoid is de-energized and the opposite solenoid is energized. Valve must be used with a NAMUR style connection. See additional information on solenoid valve operation. This valve is not equipped with solenoid coils. The customer must purchase coils seperately.

Details

Pressure: 15 to 150 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 spool is friction positioned so the valve must be mounted with the spool in a horizontal orientation.
O-Rings: Viton.
Solenoid Seat: Viton.
Materials: 360 half hard brass body, hard anodized aluminum spool, stainless steel end cap, Viton solenoid seat, composite gaskets, stainless steel fasteners.
Flow: 73.9 SCFM, 1.6 Cv
Repair Kit: ERKV-3.
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.
Fluid Media: Soft seal models are made for air, vacuum, and gases compatible with component materials. They should not be used with liquids.
Weight: 3.6 lbs ± 5%.

"E-Series" Operator - Twist Style Locking Override

This operator is equipped with a locking manual twist style override and a 1/8" NPT external pilot port. For external pilot operation, the internal pilot pressure must be blocked and the plug must be removed and external pilot source must be provided (150 psi maximum). All operators have internally threaded exhaust stems. The thread fits 10-32 UNF or 5mm-0.8 fittings. Solenoid operator is equipped with a locking manual override on the side of the solenoid structure. To activate manual override, twist the yellow lever clockwise to engage override. For replacement operators order ESPKO which is a V-599-1 operator and an EMG3 gasket (individual operator components are not available)

Material: Brass, steel, stainless steel, Viton seat.
Molding Material: Thermoplastic.
Ambient Temperature: -20°C to +50°C.
Internal Diameter Orifice: 1.3mm

"E-Series" Nut - Dust Excluder

Sintered bronze dust excluder nut, part number V-567W reduces the noise and diffuses the solenoid exhaust. The nut comes with a V-613 lock washer to improve nut retention. With this option the 10-32/5mm-0.8 tapped exhaust is inaccessible. To order standard solenoid valves with this nut, use option 'L' (e.g. ESY4L).

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.
