1000 SERIES ORIFICE CHECK VALVE

THE 1000 SERIES ORIFICE CHECK VALVE LEVERAGES A FLOW METERING ORIFICE INTEGRATED INTO THE POPPET TO AID IN DETERMINISTICALLY BIASING THE POPPET TO THE FULLY OPEN POSITION DURING FORWARD FLOW AND FULLY CLOSED DURING BACK PRESSURE EVENTS.

PATENT PENDING

  • MAIN SEAT: VESPEL

    BODY SEAL: PTFE

    HOUSING: CRES 316

  • Crack Pressure: 5 psi

    Maximum Working Pressure: 3000 psi

    Burst Pressure: 6000 psi

    Crack pressure may be increased without detriment to valve operability depending on flow metering orifice ESEOD and media.

  • Media Compatibility: Inert gas, O2*, H2, CH4

    Media Temperatures: -423°F to 200°F

    Cryogenic Internal Leakage: <5 SCIM GHe

    Ambient Internal Leakage: <1 SCIM GHe

    External Leakage: 0 SCIM GHe

    *Changes in body material are required for GOX performance. Maximum working pressure in GOX environments are subject to change based on vehicle operating conditions.

  • 1/4” line size ESEOD range: up to Ø0.070” (Cd =0.82*)

    1/2” line size ESEOD range: up to Ø0.100” (Cd =0.82*)

    3/4” line size ESEOD range: up to Ø0.150” (Cd =0.82*)

    *Discharge Coefficient Cd = 0.82 assumes choked flow at orifice.

  • AS5202 ports with sufficient depth for AS4320 fittings.

2000 SERIES PILOT CHECK VALVE

THE 2000 SERIES PILOTED CHECK VALVE LEVERAGES A PILOTING SYSTEM TO AID IN DETERMINISTICALLY BIASING THE POPPET TO THE FULLY OPEN POSITION DURING FORWARD FLOW AND FULLY CLOSED DURING BACK PRESSURE EVENTS.

THIS VALVE’S PILOTING SYSTEM ALLOWS THE VALVE TO BE OPERATED OPEN PRIOR TO HIGH PRESSURE TRANSIENTS, PROTECTING VALVE INTERNALS.

3000 SERIES DURA-CHECK VALVE

THE 3000 SERIES DURA-CHECK VALVE FEATURES A POPPET DESIGN THAT IS RESISTANT TO MECHANICAL FAILURE WHEN SUBJECT TO HIGH PRESSURE TRANSIENTS.

MECHANICAL ISOLATION BETWEEN THE POPPET AND HOUSING SIGNIFICANTLY REDUCES THE LIKELIHOOD OF METALIC DEBRIS GENERATION DURING HIGHLY VARIED FLOWS.
