Data for SR2EDTKZ
The SR2EDTKZ is a 1/4" NPTF side ported, 2 position, pilot return, solenoid operated valve with 1/8" NPTF tapped solenoid vent/exhaust with a 1/4-20 x 5/16 threaded pin indicating spool position. A knob can be attached to manually shift the spool. The spool is shifted by 25 to 160 psi external pilot air when the solenoid is energized. The spool is returned by 25 to 250 psi pilot air applied to the 1/8" NPTF port in the rear end cap and the solenoid is de-energized. See additional information on solenoid valve operation. Coil is a DIN coil with an ISO 4400 connector pattern. Coil requires an ISO 4400 style DIN cap. Standard voltage is 120/60, indicate other voltages (i.e. 12VDC, 24VDC, 240/60 etc.).
Details
Pressure: 15 to 250 psi on the main body of the valve when solenoid is externally piloted.
Vacuum: The five main ports can be operated on industrial vacuum to 28" Hg, based on a 30" barometer.
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: Buna-N.
Materials: Black anodized 6061-T6 aluminum body, hard anodized aluminum spool, A380 aluminum end cap, composite gaskets, steel fasteners.
Flow: 73.9 SCFM, 1.6 Cv
Repair Kit: ERKV-3 & 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.
Vacuum: The five main ports can be operated on industrial vacuum to 28" Hg, based on a 30" barometer.

"Classic" Operator & Coil - DIN Style w/Tapped Exhaust
The "Classic" DIN solenoid operator with a ISO 4400 din pattern connection (Form A, DIN 43650-A, 18 mm contact distance). DIN caps are ordered as a separate line item. The stem exhaust is tapped 1/8" NPTF. 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. An approved cap must be used when connecting to an electrical source. The longer tab is the ground (earth). Either shorter tab can be connected to hot (+) and the other connected to neutral (-).

General - O-Ring Information
Unless otherwise specified, all 1/4" and 3/8" soft seal valves come standard with Viton O-rings and all 1/2", 3/4", 1", 1-1/2" and 2" soft seal valves come standard with Buna-N O-rings. If a different material is required, use the dash numbers following the basic valve numbering code. For example, model RY3G-2 will have Silicone O-rings installed for a low temperature application. On valves larger than 1" consult factory on availability of O-ring materials. Additional O-ring material information.
| Dash No. | O-ring Description | Temperature Rating |
|---|---|---|
| -2 | Silicone | -80°F to 400°F |
| -3 | Viton for most aromatic gases | -20°F to 400°F, 600°F for short time |
| -7 | Urethane, 70 Durometer | -65°F to 200°F |
| -9 | Buna-N | -40°F to 250°F |
We are constantly researching O-ring materials to evaluate performance and durability in the AAA valve product line. Above is a compilation of the most commonly requested O-ring materials and the associated dash number. If you have a particular application that requires an O-ring material that is not listed, please contact us. Since we utilize standard O-ring dimensions in our valves, we can respond to the most obscure O-ring material request.
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.
