Ball Valves: SELECTOR

2 & 3-Way Ball Valve for High Pressures (FxF)
Working Pressures: 100 | 210 bar (1500 | 3000 PSI)

TECVAL selector-a-2-

TECVAL two and three-way SELECTOR ball valves are designed to allow a quick opening and close of the flow, and obtain a fast commutation and distribution. Are to be operated in a fully open or fully closed position. The superficial micro-finish of the trunnion-ball ensures a perfect sealing for both liquid and gas under high pressure or moderate vacuum service.


  • Standard reinforced PTFE seats 105 bar (1500PSI).
  • Light and compact design.
  • No ejectable stem design.
  • Anti-leak stem with double o-ring seal.
  • Two panel nuts for a better fixing.
  • 100% tested.


  • Kel-F seats for high pressures 210bar (3000PSI).
  • Degreased for oxygen service.
  • Automation through pneumatic actuator.
  • Two-way,straight flow.
