Compact Ball Valves

STANDARD MODEL

VALVE DESCRIPTION 

Compact Ball valve is a manufacturer standard design suitable to combine a compact ball valve design with robustness and reliable performances.

The valves do not rely on lubricant or grease to assist sealing between the ball and seat also when metal-to-metal sealing is used. The valve design is based on trunnion mounted or support plate configuration in order to get the operating torque as lower as possible.

BASIC CHARACTERISTICS

  • API6A design
  • Bi-directional sealing
  • Spring loaded metal-to-metal seats
  • End flange connection directly to the valve body
  • Valve stem retained by shoulder on the body as anti-blow out design
  • End flanges sized to withstand bending load up to 100% of pipe yield at full working pressure
  • Fire testing to ISO 10497
  • Compact design to save between 50% and 70% of valve weight if compared to standard ANSI

COMPACT SWING CHECK MODEL

VALVE DESCRIPTION

Compact swing check valve is a manufacturer standard design suitable to combine a compact ball valve design with robustness and reliable performances.

The valve design is based on swing clapper full opening configuration with dedicated end flanges to get the operating torque as lower as possible.

BASIC CHARACTERISTICS

  • API6A design
  • Full opening design with optimized body profile to reduce flow turbulence
  •  Spring loaded clapper
  •  Clapper-stem arrangement completely assembled inside the pressure boundary eliminating external leak path
  • End flange connection directly to the valve body
  • End flanges sized to withstand bending load up to 100% of pipe yield at full working pressure
  • Fire testing to API6FD
  • Compact design to save between 60% and 75% of valve weight if compared to standard ANSI valves.
  • Renewable seat
