Up to 210 bar (3000 PSI)

TECVAL selector-a-2-
TECVAL

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.
