Data for 683V

Print
The 683V is a 3/8" subplate style, 2 position, spring return with pilot assist, pilot operated valve, using DOW 55 grease. The valve body is coated with TUFRAM® compound, stainless steel end caps and stainless hardware for improved corrosion protection. The internal spool is shifted by 50 to 250 psi pilot air supplied to the 1/8" NPTF pilot port in the end cap of the valve. The spool is return by a spring when the pilot source is removed or by higher pilot presser applied to 1/8" NPTF pilot return port. Valve must be used with a subplate style connection. See the dedicated subplate section or the stacking manifold section. Pilot source can be routed through the subplate. The body is

Dimension PDF Parts
Pressure: 15 to 500 psi on the main body of the valve, 50 to 350 psi pilot air.
Vacuum: The five main ports can be operated on industrial vacuum to 28" Hg, based on a 30" barometer.
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 valve can be mounted in any orientation.
O-Rings: Viton.
Materials: TUFRAM® coated 2024-T3511 aluminum body, hard anodized aluminum spool, stainless end caps, composite gaskets, stainless fasteners.
Flow: 97.1 SCFM, 2.4 Cv
Repair Kit: ERKV-3W.
3-Way or 5-Way: While this valve is basically 4-way, it can be used 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.

TUFRAM®

A special surface process called TUFRAM® can be applied to all aluminum and aluminum alloy parts giving them enhanced surface properties. These properties include improved corrosion resistance, abrasion resistance, chemical resistance, moisture resistance, increased hardness, USDA-approved and FDA-approved. This process is ideal for AAA valves that are used in very harsh environments. For example, wash down areas in food processing plants that use caustic solutions for clean-up, off shore oil platforms that are subject to salt water spray, chemical processing plants or valves that must mount outdoors. Please contact us for more information on the use of TUFRAM® L-4 on your application.

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, DOW-55

Valves that are required to operate at temperatures lower than 32°F, we recommend using DOW 55 grease. This grease is not as sluggish as Magnalube-G is at these low temperatures. DOW 55 grease is not required and Magnalube-G has worked well for low temperatures. It is only an anecdotal recommendation. 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. DOW 55 is included in all valve repair kits that specify DOW 55 for proper valve maintenance. Never use any kind of oil, cup grease, or automobile chassis lubricant.

To specify the use of Dow-55 grease, use the suffix "W" to the end of the valve part number. This should be the last letter in the part number structure.

If the valve is stored for over 2 years, then a small reapplication of grease is suggested.
