Flowserve Lubricated Plug Valves – SUPER H

BRAND: Serck Audco

Super-H is the pressure balanced Plug Valve that Serck Audco has developed while leading the market over the last 90 years. With the most typical applications found in natural gas, upstream hydrocarbon and slurries, this well-established design has proven its suitability on a range of demanding applications when zero leakage or bubble tight shut-off and reliability of operation are of prime importance.

Features and Benefits

Basic design advantages of Flowserve Plug Valve such as metal-to-metal seats and a wide seating area, along with competitive pricing, have made plug valves the product of choice when the valve operates in a difficult or dirty service and/or needs to open against full differential pressure. The robust metal-to-metal seats ensure long valve life on any service, even in presence of solid particles in the line media.

Benefits

  • Certainty of zero leakage sealing down the line, even with damaged metal seats.
  • Certainty of operation with low and consistent torque which is stable over long periods of time.
  • Minimal maintenance regime.
  • Full in-line maintainability even under full pressure and without any need of shut down.
  • Assured sealing to atmosphere.

How It Is Achieved

  • Precise seat mating procedures.
  • Effective sealant injection system combined with wide seating areas.
  • Pressure balanced plug as standard, with option of Protected Pressure balance®
  • Super LoMu Anti Friction Treatment on plug and stem.
  • Precise factory set plug loading
  • Provision for sealant injection for the seats
  • Provision for stem packing re-injection
  • Independent stem sealing design that can meet stringent fugitive emissions requirements.
  • All pressure seals in fire safe metal or graphite.

Design Range
