EIGHT POSITION CYLINDERS Service Information

The Eight-Position Cylinder is a medium duty pneumatic positioning device that operates through eight pre-determined positions of 3/8" increments with a total stroke length of 2-5/8". Although it was primarily designed for power-shift transmissions it may also be utilized for indexing and any other application where a fixed stroke can be used. The ideal companion valve for the cylinder is the AVENTICS Type "P" Rotair® eight-position valve, but a suitable substitute is an electro-pneumatic switching arrangement using 3-way solenoid valves. The cylinder is extremely rugged, having an anodized, corrosion-resistant, light-weight aluminum body, pistons and piston stops.

WARNINGS-INSTALLATION AND MOUNTING

The user of these devices must conform to all applicable electrical, mechanical, piping and other codes in the installation, operation or repair of these devices. INSTALLATION! Do not attempt to install, operate or repair these devices without proper training in the technique of working on pneumatic systems and devices, unless under trained supervision. Compressed air systems contain high levels of stored energy. Do not attempt to connect, disconnect or repair these products when a system is under pressure. Always exhaust the pressure from an air system before performing any service work. Failure to do so can result in serious personal injury. MOUNTING! Device should be mounted and positioned in such a manner that they cannot be accidentally operated.

INSTALLATION Mount the 8-position cylinder in any desirable plane to a sturdy, flat surface (preferably with the ports facing down to prevent moisture accumulation) with three 3/8" bolts. Mounting lugs are cast in the body of the cylinders. Avoid misalignment with the load to be positioned since side thrust and binding will affect the service life of the rod bearing and piston stop seals. All ports are 1/4"-18 NPT pipe size. The following ports should be piped together in pairs with "T" connections: 1 with 1A, 3 with 3A and 6 with 6A. Connections should be made as close to the cylinder as possible to reduce the number of lines from the control valve.

NOTE: While the R431005699 (Old No. P -061185-00002) cylinder can be used with a number of valves, the ports on cylinder R431003808 (Old Part No. P -055557-0003) conveniently correspond directly to the portnumbers stenciled on the AVENTICS Type "P" Rotair®control valve (part number ( R431003806 orR431003807; Old Part No. P -055556-00003 or P –055556-00004). If cylinder R431003967 (Old Part No.P -056426-00004) is utilized with these valves, portnumber 2 on the valve should be connected to portnumber 5 on the cylinder and port number 5 on thevalve should be connected to port number 2 on thecylinder to provide the reversal of the neutral positionin that cylinder.

OPERATION Maximum operating pressure of the 8-position cylinder is 150 psi (10.3 BAR) at a temperature range of -40° F to 160° F (-40° C TO 71° C). The cylinder assumes anyone of its eight positions when air pressure from the control valve is supplied in accordance with the tables on pages 3 and 5.The forces developed by the cylinder are functions of exposed piston area and amount of air pressure applied, and are tabulated according to rod positions in graphs on pages 6,7, and 8.Internal springs return the piston rod to its "Neutral" position when air pressure is intentionally or unintentionally exhausted from the control lines. This is a safety feature that insures against operation in case of a loss of air supply.In the event that an application may not need the above feature, cylinder R431005699 (Old Part No. P -061185-00002)with no return springs is available.

MAINTENANCEPeriodically disassemble the cylinder for cleaning and inspection. Clean all metal parts with a nonflammable solvent and wash all rubber parts with soap and water. Rinse thoroughly and blow dry with a low pressure air jet. Replace those parts which are damaged or worn.Reassemble the cylinder, lubricating each part as it is put into place. Internal lubrication is recommended by periodic greasing of all bores and rubber parts with Dow Corning No. 55 pneumatic grease or equivalent.Check the operation of the reassembled cylinder by putting air pressure in the ports in the order as shown by the cylinder truth tables (pages 3 and 5) .Note: When disassembling the cylinder please use CAUTION as the return springs are under compression.

ADJUSTMENTThe AVENTICS 8-position cylinder needs no adjustment.

NOTICE TO PRODUCT USERS 1. WARNING: FLUID MEDIAAVENTICS pneumatic devices are designed and tested for usewith filtered, clean, dry, chemical free air at pressures andtemperatures within the specified limits of the device. For usewith media other than air or for human life support systems,AVENTICS must be consulted. Hydraulic cylinders are designedfor operation with filtered, clean, petroleum based hydraulic fluid;operation using fire-resistant or other special types of fluids mayrequire special packing and seals. Consult the factory.2. WARNING: MATERIAL COMPATIBILITYDamage to product seals or other parts caused by the use ofnoncompatible lubricants, oil additives or synthetic lubricants inthe air system compressor or line lubrication devices voidsAVENTICS warranty and can result in product failure or othermalfunction. See lubrication recommendations below.AIR LINE LUBRICANTS! In service higher than 18 cycles perminute or with continuous flow of air through the device, an airline lubricator is recommended.* (Do not use line lubrication withvacuum products.) However, the lubricator must be maintainedsince the oil will wash out the grease, and lack of lubrication willgreatly shorten the life expectancy. The oils used in thelubricator must be compatible with the elastomers in the device.The elastomers are normally BUNA-N, NEOPRENE, VITON,SILICONE and HYTREL. AVENTICS recommends the use ofonly petroleum based oils without synthetic additives, and withan aniline point between 180° F and 210° F.COMPRESSOR LUBRICANTS! All compressors (with theexception of special "oil free" units) pass oil mist or vapor fromthe internal crankcase lubricating system through to thecompressed air. Since even small amounts of non-compatiblelubricants can cause severe seal deterioration (which couldresult in component and system failure) special care should betaken in selecting compatible compressor lubricants.3. WARNING: INSTALLATION AND MOUNTINGThe user of these devices must conform to all applicableelectrical, mechanical, piping and other codes in the installation,operation or repair of these devices.

INSTALLATION ! Do not attempt to install, operate or repair these devices without proper training in the technique of working on pneumatic or hydraulic systems and devices, unless under trained supervision. Compressed air and hydraulic systems contain high levels of stored energy. Do not attempt to connect,

disconnect or repair these products when a system is under pressure. Always exhaust or drain the pressure from a system before performing any service work. Failure to do so can result in serious personal injury. MOUNTING! Devices should be mounted and positioned in such a manner that they cannot be accidentally operated. 4. WARNING: APPLICATION AND USE OF PRODUCTSThe possibility does exist for any device or accessory to fail tooperate properly through misuse, wear or malfunction. The usermust consider these possibilities and should provide appropriatesafe guards in the application or system design to preventpersonal injury or property damage in the event of a malfunction.5. WARNING: CONVERSION, MAINTENANCE AND REPAIRWhen a device is disassembled for conversion to a differentconfiguration, maintenance or repair, the device must be testedfor leakage and proper operation after being reassembled andprior to installation.MAINTENANCE AND REPAIR! Maintenance periods should bescheduled in accordance with frequency of use and workingconditions. All AVENTICS products should provide a minimum of1,000,000 cycles of maintenance free service when used andlubricated as recommended. However, these products should bevisually inspected for defects and given an "in system" operatingperformance and leakage test once a year. Where devicesrequire a major repair as a result of the one million cycles, oneyear, or routine inspection, the device must be disassembled,cleaned, inspected, parts replaced as required, rebuilt andtested for leakage and proper operation prior to installation. Seeindividual catalogs for specific cycle life estimates.6. PRODUCT CHANGESProduct changes including specifications, features, designs andavailability are subject to change at any time without notice. Forcritical dimensions or specifications, contact factory.*Many AVENTICS pneumatic valves and cylinders can operatewith or without air line lubrication; see individual sales catalogsfor details.
