Data for 802V

The 802V is a 3/8" NPTF side ported, 2 position, spring return, solenoid operated valve with externally pressurized solenoid valve. The internal spool is shifted either by 50 to 160 psi external 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 to the solenoid 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. The most common application using this valve is the "Belly-Dump" or bottom dump trailer hopper control or railroad coal car. Coil is explosion proof with 1/2"-14 conduit connection. Standard voltage is 120/60, indicate other voltages (i.e. 12VDC, 24VDC, 240/60 etc.). This valve is equipped with a lockout in position "A".

Details

Pressure: 15 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: Viton.
Materials: Tufram coated 6061-T6 aluminum body, hard anodized aluminum spool, electroless nickle A380 aluminum end caps, composite gaskets, stainless steel fasteners.
Flow: 97.1 SCFM, 2.4 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 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.
Weight: 3.1 lbs ± 5%.

"Classic" Operator & Coil - Explosion Proof

The "Classic" explosion proof solenoid operators are sturdy and tough construction with a 1/2" NPT conduit connection. The stem exhaust is tapped 1/8"-27 NPT. 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. The explosion proof operator carries the UL & CSA label for Class I, Division 1, Group C and D (gasoline vapors, etc.), Class II, Division 1, Groups E, F and G (coal , coke and grain dusts). Temperature code: T4A. Standard leads are 18". When connecting to an electrical source either black wire can be connected to hot (+) and the other connected to neutral (-). The green wire is the ground (earth). The housing of all "Classic" explosion proof solenoids cannot be rotated or serviced in the field. If coil orientation is not specified at time of order, the 1/2" conduit will be rotated towards the 2 port side of valve body.

Commonly Asked Questions

Q: Can I use a piece of equipment approved for use in a Division 1 hazardous location in a Division 2 hazardous location?
A: Yes. If equipment has been approved for use in a Division 1 hazardous location, it can be used in a Division 2 hazardous location, providing it is in the same class and group.

Q: Can equipment approved for a Class I hazardous location be used in a Class II hazardous location?
A: No. Equipment used in Class I and Class II hazardous locations are made for different purposes. Equipment approved for Class I hazardous locations must contain an internal explosion, while Class II approved equipment must seal out dust. They are not interchangeable.

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.

An alternative grease for low temperature application, refer to Dow-55 grease.

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.
