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.

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-closure 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 any primary pressure boundary including valve stem Forged material to comply with API6A PSL3 Valve actuation with dedicated hydraulic actuator and ROV operable Gearbox (fixed or retrievable) PRODUCT RANGE DESIGN FEATURES MATERIAL SELECTION Model: SubSea Side Entry Ball Valves Pressure Classes: 3000 psi /900-1500 lbs Size: 1/2” to 48” Pressure Classes: 5000 psi / 2500 lbs Size: 1/2” to 30” Pressure Classes: 7500 psi Size: 1/2” to 22” Pressure Classes: 10000 psi Size: 1/2” to 12” Pressure Classes: 15000 psi Size: 1/2” to 12” 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.
