10CV-15CV-Pipe Connection Check Valves
IntroductionHikelok O-Ring check valves with coned-and-threaded connection type. Provide unidirectional flow and tight shut-off for liquids and gases with high reliability. When differential drops below cracking pressure, valve shuts off. Hikelok Ball check valves prevent reverse flow where leak-tight shut-off is not mandatory. When differential drops below cracking pressure, valve closes.With all-metal components, valve can be used up to 650°F(343°C).
FeaturesViton (FKM) O-ring: 0° to 400°F (-18° to 204°C)Buna-N O-ring: 0° to 250°F (-18° to 121°C))FFKM O-ring: 30° to 500°F (-18° to 260°C)PTFE O-ring: -100° to 400°F (-73° to 204°C)PTFE O-ring with Low Temp Spring: to -100°F (-73°C)Ball and poppet are an integral design to assure positive,in-line seating. Poppet is designed essentially for axial flow with minimum pressure drop
AdvantagesCracking Pressure: 20 psi (1.38 bar) ±30%. Springs for higher cracking pressures up to 100 psi available on special order for O-ring style check valves onlyCracking Pressure: 20 psi (1.38 bar) +/- 30% Optional cracking pressures not available in Ball Style Check ValvesInstallation: Vertical or Horizontal as required. Flow Direction Arrow marked on valve body.
