This valve is available with a male 1/4" NPTFconnection and is recommended for pneumatic service.Valve SpecificationsMaximum Operating Pressure:250 PSIGCracking Pressure: 1 to 2 PSIGOperating Temperature:Standard: 0° to 180° F** Ambient temperatures below freezing require moisture-free air. Ambienttemperatures below freezing and above 180° require lubricants especiallyselected for suitability at these temperatures. Pneumatic valves should beused with filtered and lubricated air.Component MaterialsBody Material................................................................BrassInternal Components........................Brass / Stainless SteelSeals...............................................................................NitrileModel SelectionModelNumber2.31(59)PipeThreadFlow †(SCFM)03047 0099 1/4" 30General InformationPush-to-Connect check valves that ensures protectionagainst reversal of flow. The valves have an arrow moldedinto the body to indicate the direction of flow.
