Data for SY3PMONOSZ

The SY3PMONOSZ is a 3/8" subplate style, 3 position, spring centered, closed center spool, double solenoid operated valve with a twist non-locking solenoid override with a knob directly attached to the internal spool to override spool position. It also indicates spool position. The spool is shifted by 50 to 160 psi external pilot air when the solenoid is energized, or when using the override. 50 to 160 psi must be maintained on external pilot port to keep the spool shifted while the coil is energized, or when using the override. The spool is spring centered when both solenoids are de-energized. Valve must be used with a subplate style connection. See the dedicated subplate section or the stacking manifold section. See additional information on solenoid valve operation. Coil is a Mold-Over with 1/2"-14 NPT conduit connection. Standard voltage is 120/60, indicate other voltages (i.e. 12VDC, 24VDC, 240/60 etc.).

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 - Mold-Over

The "Classic" Mold-Over solenoid operator with a 1/2"-14 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 (-). The green wire is the ground (earth).

"Classic" Override - Non-Locking Twist

Manual override provides a method to shift the valve in case of an electrical failure or during proofing of the electrical control circuit. A knurled knob, operated by hand, physically lifts the poppet off its seat. Air pressure to the solenoid is required to shift the internal spool. The knob will only remain in the ON position while held, once released it will move back to the OFF position. Twist the knob clockwise to lift the poppet.

Subplates for 3P Valves - 1/4" Ports

Subplated valves require a mounting base. This mounting base is pre-plumbed to existing control lines. Due to the nature of the plumbing lines fixed to a mounting base, replacing subplate mounted valves is rapid and quick. All port connections, excluding "External Pilot" or "Pilot Return" ports, if used, are made through O-ring sealed holes in the base of the valve through a subplate. O-ring seals and mounting screws are furnished with each subplate valve.

The typical sublates are listed below from the most commonly used to the least commonly used.

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 - 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.
