20CV-Medium Pressure Check Vlaves


Hikelok Medium Pressure Check Valves, nicknamed are designed for use with 20 Series valves and Hikelok Medium Pressure tubing. They incorporate conedand-threaded connections with the orifice sized to match the high-flow 15,000 psi tubing options shown later in this brochure. For instructions on how to make this Medium Pressure Cone & Thread connection and the tools necessary to accomplish,


  • Utilize High Flow Medium Pressure Coned-and-Threaded connections

  • Tubing sizes available from 1/4" to 1"

  • Working temperature from 0°F to 400°F (-17.8°C to 204°C)

  • Maximum working pressure up to 20,000 psig (1379 bar)


  • Prevents reverse flow where leak-tight shut-off is not mandatory (Not for use as relief valve)

  • Cracking pressure: 14 psig~26 psig (0.966 bar~1.794 bar)

  • Provides unidirectional flow and tight shut-off for liquids and gases with high reliability. When differential drops below cracking pressure, valve shuts off (Not for use as relief valve)

  • Resilient O-ring seat design for noise-free closing and zero leakage

  • An integral design of the ball and poppet to assure positive, in-line seating without "chatter".Poppet is designed essentially for axial flow with minimum pressure drop

More Options

  • Optional O-Ring and ball type

  • Optional wetted materials of cover gland and ball poppet for longer life

  • Optional special materials available when corrosion, temperature, or NACE/ISO 15156 requirements demand
