Specification Brand : LOZOME BulletPoint : Pack of 3 BulletPoint1 : 100% brand new and high quality,Cracking Pressure:4.5 psi BulletPoint2 : Max Pressure:1000 Psi For Water, Oil,Gas (WOG1000),Port Types: Female NPT x Female NPT BulletPoint3 : Working Temperature:-51°C to 232°C (-60°F to 450°F),Seals:NBR BulletPoint4 : Check valves are used to help direct flow in one direction. The stainless steel bodies and PTFE seals are highly corrosion resistant allowing these check valves to be used with a wide variety of fluids including, but not limited to water, oil, gas, air, light alkali's, acids, biodiesel, fuels and alcohols BulletPoint5 : Vertical check valves may be used for any application. They utilize a spring system which shuts the Disc closed when there is not enough pressure to hold it open by the operating fluid. Fluid pressure in the backwards direction will cause the valve to close to prevent backflow Color : Gold ConnectorType : Slip Department : Men ExteriorFinish : Stainless Steel ExternallyAssignedProductIdentifier : 5053792148943 ExternallyAssignedProductIdentifier1 : 752812517596 ExternallyAssignedProductIdentifier2 : 0752812517596 GpsrSafetyAttestation : 1 IncludedComponents : industrial-check-valves ItemName : 1/2" Female WOG1000, Vertical Check Valve, 304 Stainless Steel, NPT Spring Loaded in-line Low Cracking Pressure CF8M ItemPackageDimensions_Height : 8.6106 centimeters ItemPackageDimensions_Length : 3.4036 centimeters ItemPackageDimensions_Width : 5.7912 centimeters ItemPackageQuantity : 1 ItemTypeKeyword : industrial-check-valves Manufacturer : LZ Material : Stainless Steel Material1 : Plastic Material2 : Rubber MaximumOperatingPressure : 1000 pounds_per_square_inch ModelName : Walfront50b1agunr3 ModelNumber : SS0128-ZJ NumberOfItems : 1 NumberOfPieces : 1 NumberOfPorts : 2 PackageLevel : unit PartNumber : SS0128-ZJ ProductDescription : Note: Check valves do not create a 100% seal against backflow like a ball valve would. If prevention of backflow is desired, two check valves should be used in series with each other. Any fluid which finds its way past the first check valve is unlikely to have enough pressure to pass through the 2nd. For use with biodiesel, this check valve will require changing of the NBR seals to a more resistant seal Meets International Organization for Standardization (ISO) standard 9002.
