Catalog <strong>WACC</strong>-<strong>01</strong>/USA<strong>Flow</strong> Control Valves<strong>Flow</strong> <strong>Controls</strong> & <strong>Accessories</strong>“SPF” Series – 1/8" to 1/2" PortsComponent MaterialsBody Material: BrassNeedle: Stainless SteelBall Check: Stainless SteelCheck Retainer: AcetalNeedle Seals: Nitrile (Standard),Fluorocarbon (Optional)Knob: AluminumDECFB(Open)A(Both Ends)General InformationThe “SPF” Series <strong>Flow</strong> Control Valves meter flow ofair or oil in one direction and allow free flow in thereverse direction.“SPF” Series valves are manufactured with a two stepneedle. Fine metering is accomplished over the initialadjustment turns and nominal metering is providedover the remaining turns. Once the desired flow isselected, a set screw can be tightened to maintain thesetting.These valves are available with NPTF ports in 1/8",1/4", 3/8", and 1/2" sizes.Valve SpecificationsMaximum Operating Pressure2000 PSI Non-ShockCracking pressure for return check poppet –5 PSI NominalOperating TemperatureStandard: 0° to 140° F*-40° to 140° F (Hydraulic service)Extended Temperature: 0° to 400°F** Ambient temperatures below freezing require moisture-free air.Ambient temperatures below freezing and above 180° requirelubricants especially selected for suitability at thesetemperatures. Pneumatic valves should be used with filteredand lubricated air.Model Selection and DimensionsModelNumberA Port Size B C D E FSPF200B 1/8-27 NPTF 1.50 1.75 .625 1.06 .75SPF400B 1/4-18 NPTF 1.80 2.38 .812 1.41 .81SPF600B 3/8-18 NPTF 2.25 2.75 1.000 1.75 1.00SPF800B 1/2-14 NPTF 2.72 3.19 1.250 2.06 1.19For units with Fluorocarbon seals, add suffix “V”.
