SUBSEA TOP ENTRY BALL VALVES

VALVE DESCRIPTION

Subsea top entry ball valves are designed according to API6DSS, API6A, API17D with the addition of customer requirements when present.
The valves do not rely on lubricant or grease to assist sealing between the ball and seat.
Metal-to-metal sealing is used between the ball and seat and non-elastomeric seal are provided between the seat and body.
Metal-to-metal sealing is also provided between body-to-bonnet and stem-to-body (optional). The Subsea ball valves are actuated by Perar hydraulic actuator or gearbox as requested.

BASIC CHARACTERISTICS

  •  API6DSS, API6A, API17D design as requested
  • Bi-directional sealing
  • Spring loaded metal-to-metal seats (tungsten carbide coating 0,2 mm – 0,4 mm thickness)
  • Anti-blow out design stem
  • Non-elastomeric seals to avoid the risk of gradual degradation of the seals over their life
  • Full metal-to-metal sealing at body-bonnet and valve stem
  • Forged material to comply with API6A PSL3
  • Valve actuation with dedicated hydraulic actuator and ROV operable Gearbox (fixed or retrievable)

SUBSEA SWING CHECK VALVES

VALVE DESCRIPTION

Subsea swing check valves are designed according to API6DSS, API6A, API17D with the addition of customer requirements when present.
The valves do not rely on lubricant or grease to assist sealing between disc and seat. Metal-to-metal sealing is used between disc and seat and the seat is welded to the valve body; both seat and disc are hardfaced with UNS N06625 or Stellite.Metalto-metal sealing is also provided between body-to-bonnet and stem-to-body (optional) in case of ROV operated valves. The Subsea ball valves can be provided to be locked open by ROV.

BASIC CHARACTERISTICS

  • API6DSS, API6A, API17D design as requested
  •  Bi-directional pigging
  • Metal-to-metal seats (3mm hardfacing with Stellite 6 or Inconel 625)
  •  ROV lock open stem design to keep valve fully open for reverse pigging.
  •  Non-elastomeric seals to avoid the risk of gradual degradation of the seals over their life
  • Full metal-to-metal sealing at body-bonnet
  • Seat integral to valve body and with slope to engage the seat-to-disc sealing at low pressure
  • Forged material to comply with API6A PSL3Valve actuation with dedicated hydraulic actuator or ROV operable device.

TC SLABS GATE VALVES

VALVE DESCRIPTION

 

Subsea through conduit gate valves are designed according to API6DSS, API6A, API17D with the addition of customer requirements when present.
The valves do not rely on lubricant or grease to assist sealing between the gate and seat. Metal-to-metal sealing is used between the gate and seat and between the seat and body. Metal-to-metal sealing is also provided between body-to-bonnet and stem-to-body at fail position via backseat.
The Subsea gate valves are actuated by hydraulic actuator or gearbox as requested.

BASIC CHARACTERISTICS

  •  API6DSS, API6A, API17D design as requested
  • Bi-directional sealing
  • Floating spring energized metal-to-metal seats (tungsten carbide coating thickness 0,25 mm on seats and 0,4 mm on gate)
  • Non-elastomeric seals to avoid the risk of gradual degradation of the seals over their life
  • Full metal-to-metal sealing at any primary pressure boundary including valve stem at fail position with the option of double backseat to provide metal sealing at both open and close positions.
  • Downstream sealing with pressurized body cavity to assist fail safe stroke
  • Forged material to comply with API6A PSL3
  • Valve actuation with dedicated hydraulic actuator and ROV operable Gearbox
