High Quality Factory Wholesale Ball Valve Trunnion mounted Ball Valve
A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball to control flow through it.
It is open when the ball’s hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle.
The handle lies flat in alignment with the flow when open, and is perpendicular to it when closed, making for easy visual
confirmation of the valve’s status. The shut position 1/4 turn could be in either CW or CCW direction. (S = SHUT, O = OPEN)Trunnion mounted ball valve NPS:2″-56″
