Data for ESR4PHOC

The ESR4PHOC is a 1/2" subplate style, 2 position, pilot return, solenoid operated valve with a twist locking solenoid override with a side exhaust nut on solenoid stem. 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 by 25 to 160 psi pilot air applied to the 1/8" NPTF port in the rear end cap and the solenoid is de-energized. Valve must be used with a subplate style connection. See the dedicated subplate section. See additional information on solenoid valve operation. Coil is a 30mm wide, high temperature coil with ISO 4400 connector pattern. Coil requires an ISO 4400 style DIN cap. Standard voltage is 120/60, indicate other voltages (i.e. 12VDC). Additional voltages available on special order.

Details

Pressure: 25 to 150 psi on the main body of the valve when solenoid is internally piloted, 25 to 160 psi return pilot air.
Vacuum: The valve cannot be vacuum operated when the solenoid is internally piloted, 25 to 160 psi return pilot air.
Temperature: -20°F to 180°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: Buna-N.
Solenoid Seat: Viton.
Materials: Black anodized 356-T6 aluminum body, hard anodized aluminum spool, A380 aluminum end caps, Viton solenoid seat, composite gaskets, steel fasteners.
Flow: 215 SCFM, 5.0 Cv
Repair Kit: ERKV-4.
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.

"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" Coil - Option H - High Temperature

The high temperature coils utilize a Form A/ISO 4400 DIN style connection (DIN 43650-A, 18 mm contact distance) with one ground tab and two voltage tabs. DIN caps are ordered as a separate line item. The coil is 30mm wide. Coil can be rotated in 45° increments on operator stem when space is available. 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 (-).

Voltage	Pick-Up	Holding	Resistance	Spare Coil
120 volts, 60 Hz		6.8 VA	741 ohms	V-603-1
12 volts D-C		4.5 Watts	55 ohms	V-603-2

Molding Material: Thermoset resin.
Ambient Temperature: -20°C to +80°C.
Relative Duty Cycle: 100%.
Degree of Protection: IP65 with connector.
Voltage Tolerance: ± 10%.
Resistance Tolerance: ± 8% at 20°C.
Insulation Class: H

General - DIN Cap - ISO 4400

DIN caps are not supplied with standard solenoid valves. These caps must be ordered separately. There are several styles of DIN caps. When ordering LED indicator types, you must specify voltage of solenoid coil. All caps listed in the table are for ISO 4400. LED indicator type caps are equipped with varistor surge protection.

Subplates for 4P Valves - 1/2" Ports with Pilot

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, including "Pilot Return" ports, if used, are made through O-ring sealed holes in the base of the valve through a subplate, excluding "External Pilot" on solenoids. 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.

Part Number	Description	Image
SP4-3	1/2" Side ported, dual exhaust, with pilot ports.
SP4-1	1/2" Bottom ported, dual exhaust, with pilot ports.
SP4-4	1/2" Side ported, single exhaust, with pilot ports.
SP4-2	1/2" Bottom ported, single exhaust, with pilot ports.

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.

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.
