3 Dimensional sketches shouldaccompany orders for cylinders equipped with times standard length: Studded rod-endthreads: Two times standard length rod-end threadsare available using high strength steel studs onmany industrial type and cushionvalve position changes:On NFPA type cylinders,ports, are normally atposition 1. By calling outthe position numbers forthe desired locations forhead and cap ports,many mounting styles can be assembled with portslocated at 90 or 180 from such special assemblies the cushion needle andcheck valves are also repositioned because theirrelation with the port position does not cushion needle valve in interchangeable with thecheck valve in many cylinder heads.

4 The cushionneedle valve can be assembled on side 4 with checkvalve on side 2 for most mountings when the port isat the standard side Trunnion mounting styles D, DB and DD, thecushion needle valves are provided only on the sideposition 3 or the head or cap which accommodatesthe mounting. The opposite head or cap can location of the cushion needle valve or checkvalve can be located in relation to the port at thecustomers port options : Extra ports: If specified onyour order, most industrial cylinders can be suppliedwith extra ports on the sides of heads or caps thatare not occupied by mountings or cushion ports: The SAE straight-thread O-ring port isrecommended for hydraulic applications .

5 It can befurnished on most cylinders on ports: Oversize NPTF ports can beprovided on most cylinders. Welded port bosses,one size larger than standard, are provided whichprotrude from the side of the head or cap. Specialthicker heads or caps can also be supplied for extraoversize combinations:On NFPA type cylinders,we can provide standardmountings in differentcombinations. For example,style J, rectangular flangemount, on head end withstyle C, side lug mount,on cap adjusters:If you require anadjustable stroke, wehave several strokeadjusters, includingthe one shown. It issuitable for infrequentadjustment and is return: Many standard double-actingcylinders can be modified to single-acting, springreturn cylinders.

6 This depends on the load condi-tions and friction factors as to whether the properspring can be provided. The factory must also knowwhether the spring is to advance or return the pistonrod. Please consult factory before ordering service: Many standard air cylinders can bemodified for water service. This involves addingcorrosion-resistant plating to heads, caps andpistons. Stainless steel piston rods with hardchrome plating are also recommended. Maximumoperating pressure or load and speed conditionsmust be considered before ordering due to thelower tensile strength of stainless steel practical foruse as piston Cylinder Division Plant Locations See Page SeriesPneumatic SeriesFeature2H3 HVH3 LHD2 AMANon-Lube (N)* (1) High Water Content Fluids (J)** Special Piston Rod Ends (1) Rod End Threads 2 X Std.

It s a major innova-tive refinement over typical cast iron piston ringseals, and Nitrile or fluorocarbon HI LOAD piston assembly overcomes theinherent problems commonly associated withthese conventional types of seals, such asscoring of the cylinder bore due to contamina-tion, and it virtually eliminates leakage flow.

9 Itcan also reduce or eliminate the need for stoptubing. It has much greater side load carryingcapacity. And most importantly, even at pres-sures up to 3,000 psi, it has a longer wearing lifethan any seal we have tested to Cylinder Division Plant Locations See Page effective s bronze-filledPTFE ring HI LOAD piston assembly is comprised of two square-cut bronze-filled PTFE piston rings (A) with Nitrile rubberexpanders underneath (B) and two non-metallic wear rings(C) which uniquely work together, incorporating the bestqualities of both elements to achieve dramatic exclusive Parker HI LOAD PistonComparative Piston Seal FrictionVirtually zero leakage.

10 The HI LOAD piston assemblymeans virtually zero leakage with hydraulic and/or waterbase fluids because of the continuous bronze-filled PTFE rings with a homogenous inner ring of Nitrile rubber to applyseal preloading. The Nitrile expanders provide enough initialradial force to eliminate low pressure leakage. At higherpressure (above 2,000 psi) the seals are pressurized under-neath, and are therefore dynamically self-sealing just as castiron rings bronze-filled PTFE resists extrusion in the clearancebetween the piston much better than Nitrile, and, as a result,provides at least double the life, increasing life spans aspressure goes scoring.
