- Trunnion Mounted Ball Valves

From

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.

  • 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
