OESIGNThis design concept consists ot a Match4round SFDOL &SLEEVE"assembly which controls the main valving unc.tions. Thls match-ground it creates an "Alr Bearing" effectfor extended nd fficient operaiion nd eliminates he nsedtor resilienl seals. Large capacily air flows are achieved byapplication t the sMc u.s. Patents ppllcable o this type ofvalve.Should he valve equire isassembly or maintenancethe SDool nd Sleeve hould be retalned s a unit.GENERAL:These alves re compact, eavy uty matched round spooland slsve air valves ntended or general ndustrial ervice.

HOWTHEVALVE ORKS:The spring holds he spool ully up. When pilot pressure sintroduced nto ha "A" pllot chamber, hls pressure cta onthe end of the soool. and orces t down. When his Dressurebcomes high enough, it forces the spool down andcomprssses he spring. Wien the pilot chamber sexhausted, he pressure galnsi he spool decays, and lhespring elums h6 spool o lhe up posltlon.PILOTDENTIFICATION:The officlal standard or diagramming lr loglc is NatlonalFluid Power Associatlon Recommended tandard T3.28.9-1973 "Method of Diagramming or Moving Part FluidControls." The sntire standard is bullt around theldentification f the spring end of th valve as the "9" endand the end opposite he spring as the "A" end, The valvebody carries his identificatlon nd conformEwith the NFPAstandard.

PILOTPRESSURE HARACTERISTICS:Ths sDool has ng aeals, and is balanced o air pressures.Thus th pressure n the valve has no eflect on the pilotpressure equlred o shift the spool. Tho pilot presaurerequlred 3 always onstant, egardless f the pressure n themainpassages.This eature makes he valve n ideal companion or air ogicsystems, ssuring onslant esponse rom cycle o cycle. Noothertype of valve ctlon provides his constant esponse.The standard utput pressur or moving part air logic is 50PSIG 3.44Bar).The 25 PSIG pllot pr$sure required o shlftthis valve gives approximately h samo response o shitl

MULTI.PURPOSE LOW PATTERNTrue mulii.purpose valve. any porl may be pressurized, back'pressured.or plugged without aftecting spool action. ANSI symbol shows thevalve as a single inlel 4.way, bul valve may be used, withoul modilica.tion, as a dual inlet 4.way, a 3.way, or a 2-way, by piping and/orplugging lhe appropriate ports.

MOUNTINGfntended for si,lb'plate or manitold rnounting. May be mounted in anyoosition,

DESIGNJThis design concept consists ol a Malch-Ground "SPOOL & SLEEVEassembly which controls the main valvinq functions. This match-ground fil creates an "Air Bearing' elfect lor extendd and elficientoperaiion and eliminates lhe need for resilient seals. Large capacityair flows are achieved by application ol the SMC U.S. Patents appli-cable to this type of valve. Should the valve require disassembly formaintenance he Spool and Sleeve should b retaind as a unit.

GEI/EFALHeavy duty air valves built to comply with Jlc and all induslrial stan-dards. Designed specifically fo. use in co-operation with air logicRcessed non'locking manual operato( availablo on all models, lype''N" and "O" valves operaie through "external" palot pressure supplyport on top of valve. Type "A" and "8" valvs may be operated through''internal' pilot pressure sopply porl situated in either their sub-plale(SPA)or slacking manitold blocks (IVBA).

PILOT DENTIFICATION:The otficial standard or diagramming air logic is National Fluid PowerAssociation Recommended Stanclard T3.28.9-1973 Method oI Dia-gramming for Moving Part Fluid Controls." The ntire slandard is builaround the idenlification of the pilots as "A" and "8". Tho valve bodycarries his identification ahd contorms wilh th NFPA standard.

PIIOT PRESSURE CHARACTERISTICSTho spool has no seals, afld is balanced to air pressures, Thus thepressur in the valve has no eflecl on the pilot pressure required loshift $e spool, Th pilot gressure reguired is always constanl, re-ga.dless of the pressure n lhe main passages.

This fature makes the valves the idoal companion tor air logic sys't6rhs, assuing a constant response irom cycle to cycle, No otherlype ol valve action provides his conqtant response,

Ihe slandard outplJl prssure lor n\ovilg patl air logic is 50 PSIG(3.44 Bar). The low pilot pressure required by these valves gives extremely fast r esponse to energize, Minimum volume o{ the pjlochambr, and small swepl volume displaced by the shorl-slrokes0001 also aid last resoonge.

PILOT PRESSURE PORTSType A & B SMC Class 1 valves are designed lo accept Pilot Pres-sures "lnternally-' lntrconnecting pilot passaqes located in thebase of the valve automatically channel pilot air to lhe appropriateoperating chambels of the valve when the valve is mounted ontoeither a pilot ported subplate or lhe MBA manifold blocks.

Pilot volumes have been held to a practical minimum. This.coupled with the xtremely hort spool stroke and tow pitotpressure required for actualion, provides remarkably as tresponse o the ncoming ilotsignal.
