Ball.

  • The NAF Trunnball DL is a full-bore trunnion-mounted ball valve, developed by Flowserve engineers with more than 80 years of experience manufacturing ball valves. The ball is supported by two large, low friction trunnion bearings for consistent low torque even at high differential pressures. Due to its bi-directional tightness, low friction and high controllability, it is an excellent choice for isolation, on/off and modulating control applications.

  • The Valbart VB2 and VB3 are repairable, bolted body, side-entry, trunnion-mounted ball valves featuring a fixed ball and floating seat rings. They are compliant with API 6D and 6A.
    Bolted-Body Side-Entry
  • The Valbart VW1 is a API 6D-compliant, welded-body valve that seals off both seats at the same time and allows bleeding of the entrapped cavity pressure (double block and bleed) with the ball in the closed position.
