PRO & PRCPRESSURE RELEASE VALVESC Pressure Release Valves are available in normally open andnormally closed configurations. All of the valves are air actuatedand are compatible with most fluids including water and syntheticcompounds. Seals are Buna-N as standard (-N). Substitute “ –V “for Viton ® seals or “–E” for EPR.Typically, pressure release valves are used to release pressure onsingle acting cylinders, hydrostatic test applications, or forproviding a safety relief in a circuit.AIR PILOTAIR PILOTPTPTPRC SERIESLPRO SERIESPILOTLPRESSUREPRESSUREDDPILOTModel No.RETURNNormalConditionARETURNPILOT OPERATED PRESSURE RELEASE VALVEPilot RatioforActuationMax OpPressure(psi)Connection PortsPressure Return PilotCracking Press.Reverse Flow(psi)PilotPress.atMax.

DRV DIRECT ACTINGRELIEF VALVESC Hydraulic Engineering direct acting relief valves are available in 1/4” NPT and9/16-18 60° cone high pressure fitting for relieving pressures from 100 to 60,000 psi.The stainless steel construction makes these valves suitable for hydraulicfluids, water and gas applications. Standard seal material is Buna-N (-N).Substitute a “-V” for Viton ® or “-E” for EPR after the part number for theseseals.

APS AIR PILOTSWITCH VALVEThe APS Air Pilot Switch consists of a high pressuresensor operator connected directly to a three-wayair valve that can be operated eithernormally open (passing air) or closed (notpassing air). The spring in the sensorapplies a counteracting force to theswitch and is adjustable within thespring range.All air pilot switches are subject to deadbandconditions, which should be considered when usingthe valve. A deadband is described as thedifference in pressure between a set point of sensing pressure and a pressure at whichthe air valve returns to the original position. Deadband conditions vary by pressure rangein percentage with higher pressure conditions reducing the deadband range.SC will preset the APS to a specified pressure if requested. Indicate if the switch is toactivate under increasing or decreasing pressure condition. Consult SC for moreinformation if needed.LOW PRESSUREAUTO ONHIGH PRESSUREAUTO OFFAIRSUPPLYTO REMOTEPILOTGASSUPPLYSIGNALN.C.N.O.HIGH PRESSUREOUTLETSIGNALTYPICAL AUTO ON/OFF SETUP
