V-Port Ball Valves

V-notched segment ball valves for fibre, slurry and viscous media — flanged, high-pad, full-bore and wafer builds with near-equal-percentage control. Images are representative renderings of each series; finish, accessories and nameplate follow the confirmed drawing.

The one-piece full-bore design opens a passage close to the pipe bore, so capacity is gained without going up a line size; the body is cast in one piece with no body joint to leak. The V-notched segment ball still gives near-equal-percentage control and shears through fibre and solids, and the seat carrier, adjustable stem and square-shaft drive are shared with the rest of the V-port range. Sizes DN100–DN300; PN10 / PN16 / PN25 or 150LB; −29 to 350 °C, −29 to 700 °C on request; Class V / Class VI, uni- or bi-directional.

One body, no body joint to leak

The one-piece full-bore body has a passage close to the pipe bore and no split line, so there is no body joint that can leak to atmosphere. On a line where the medium is both abrasive and a leak risk, that is the reason to take this build over the two-piece.

The trade is maintenance: the ball and seat are reached from the pipe end, so the valve comes out of the line for a seat change.

What full bore is worth

Capacity is gained without going up a line size, and the pressure drop across the valve stays low. On a gravity or low-head line that is often the difference between making the flow and not.
