DAN SPEED S316 Stainless Steel Vertical Check Valve,Spring Loaded In-line Low Cracking Pressure 2 inch

  • Body Material:Stainless Steel SUS/SS316,Cracking Pressure:4.5 psi.
  • Working Temperature:-51°C to 232°C (-60°F to 450°F),Seals:NBR.
  • Max Pressure:1000 Psi For Water,Oil,Gas (WOG1000),Port Types:BSPP Female x BSPP Female.
  • 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.
  • 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.
