Ball Valves: SELECTOR

2 & 3-Way Ball Valve for High Pressures (FxF)
Up to 210 bar (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.
