IntroductionFollow these instructions when installing, operating, or servicing the product.Application LimitsThese products are intended for use in general purpose compressed air systems only.Operating Pressure Range:kPapsig bar Minimum 24035 2.4Maximum103015010.3Ambient Temperature Range: -18°C to 71°C (0°F to 160°F)!CAUTION: An interruption of 10 milliseconds or greater tothe power supplied to the solenoid of a solenoid operated valve may cause the valve to shift. Provision must be made to prevent power interruption of this duration to avoid unintended, potentially hazardous, consequences.Installation:1.Valve will mount in any position.!CAUTION: It is recommended that double solenoidand double remote air pilot operated 3-Position valves be mounted so that the axis of the valve spool is in the horizontal plane.2.Detailed piping and mounting dimensions are shown.3.Solenoid voltage ratings are described on the nameplate.Y our electrical power source must agree with this rating.The coil identification chart indicates the various voltages and Hertz ratings available.4.Check model number on valve against valve model chart.On a single pressure, dual exhaust model; For inline valves, pipe the supply pressure to Port “1”. For inline valves; pipe the supply pressure to the “IN ” Port.5.Cylinder speed can be controlled by restricting the exhaust port of the valve with flow controls.!CAUTION: DO NOT close off exhaust ports.6.Pilot pressure when separately supplied, should be approximately equal to inlet pressure but not less than 40PSIG (2.8 bar) or more than 150 PSIG (10 bar).7.To obtain maximum valve life with a minimum of maintenance, it is necessary that filtered and lubricated air be used.Valve should be installed with reasonable accessibility for service whenever possible – repair service kits are available. Keep pipe or tubing lengths to a minimum with inside clean and free of dirt and chips. Pipe joint compound should be used sparingly and applied only to the male pipe – never into the female port.Do not use PTFE tape to seal pipe joints – pieces have a tendency to break off and lodge inside the unit, possibly causing malfunction.Air applied to the valve must be filtered to realize maximum component life.Wiring InstructionsFollow all requirements for local and national electrical codes.SymbolAPBCE#143-Position Double SolenoidCE#14APB3-Position Double AirInstallation & Service Instructions V -295HP42 Series 3-Position Valve Inline / StackingDouble Air / Double Solenoid Single PressureISSUED: September, 2000Supersedes: October, 1999ECN# P27805Pneumatic Division North America Richland, Michigan 49083!!WARNINGTo avoid unpredictable system behavior that can cause personal injury and property damage:•Disconnect electrical supply (when necessary) before installation,servicing, or conversion.•Disconnect air supply and depressurize all air lines connected to this product before installation, servicing, or conversion.•Operate within the manufacturer’s specified pressure, temperature,and other conditions listed in these instructions.•Medium must be moisture-free if ambient temperature is below freezing.•Service according to procedures listed in these instructions.•Installation, service, and conversion of these products must be performed by knowledgeable personnel who understand how pneumatic products are to be applied.•After installation, servicing, or conversion, air and electrical supplies (when necessary) should be connected and the product tested for proper function and leakage.

CONTACT YOUR LOCAL REPRESENTATIVE.42 Series 3-Position Valve V-295HPMaintenance Hints & TroubleshootingValve Not Shifting Completely:1.Be sure supply pressure is 40 PSIG or greater at the valveduring the shift.2.Check for possible restrictions in air supply, such as sharpbends and undersize hose fittings.3.Check for possible pilot exhaust restriction.4.Check spool for smooth movement.5.Check seals and gaskets for improper installation, dirt anddamage.Slow Air Leakage Though Exhaust Ports:1.Check for internal leakage in the cylinder being operatedby the valve.2.Check condition of seals on spool and the valve body bore.3.Check condition of seal on poppet assembly and their matingsurfaces in the pilot body.4.Check for missing, damaged or incorrectly assembled sealsand O-rings.Noisy Solenoid:1.Check voltage and frequency.2.Inspect fixed pole assembly for nicked and damaged matingsurfaces and dirt. Replace parts, if damaged.3.Check override access area for excessive dirt.Valve Service Procedures:!CAUTION: Always shut off air supply and bleed off trapped pressure in the valve. For solenoid operated valves, turn off electrical power source.PREP ARATION: Lightly lubricate all rubber soft goods (o-rings, gaskets, and spool seals) found in the service kits. Use non-detergent hydrocarbon base oil, or grease (preferably grease). This lubrication will help retain seals and gaskets in position for easier reassembly.!CAUTION: DO NOT use synthetic oils such as esters or fire retardant type compressor oils.Servicing Valve BodyT o Disassemble:1.For “Stacking” solenoid operated valves: Follow steps 1and 2 under servicing solenoid section and pilot body.2.For “Inline” solenoid operated valves: Follow step 2 underservicing solenoid section and pilot body.3.Air pilot valve: Remove both air pilot operators (Item 19)from valve body by loosening the two end mounting screws (Item 21).4.Remove the piston (Item 28) from each end of valve bodybore.5.T o disassemble the main valve, loosen the two spool screws,and remove all internal parts.!CAUTION: Slowly loosen the two spool screws to avoida rapid release of the spool screw, shoulder sleeve,and spring retainer, due to the compression ofcentering springs.6.The spring retainer and shoulder sleeve at the oppositeend of the spools must also be removed.7.Thoroughly clean the valve interior and inspect for nicks,voids, pits, and deep scratches.T o Reassemble:1.Place shoulder sleeve (Item 25) inside spring retainer(Item 26). Insert spool screw (Item 24) and attach to the spool (Item 23) with engagement of two (2) full threads. 2.Slide one (1) centering spring (Item 27) over the spool andinstall into the valve body bore.3.On the opposite end of the valve, install the remainingcentering spring, shoulder sleeve, spring retainer and spool screw.NOTE: Tighten spool screws to 5.1 to 6.8 Nm (45 to 60 in. lbs.).4.Replace piston O-rings (Item 29) and install into each endof valve body bore with the flat surface outward.5.Solenoid operated valve: Insert mounting screws (Item 7A)into pilot body. This will assist you in positioning the pilot body to adaptor body gasket (Item 16), the adaptor plate (Item 17), to body gasket (Item 18) for easier mounting to the valve body.
