The rotary valve design provides shear action between the V-notched ball and the seat, promoting smooth, clogging free operation.

The through-flow design provides high capacity for the fluid.

Single seat design, torque is lower than typical trunnion design valve, easy to operate, reduce the cost of actuator.

Two seat design: Seat provides ASME/FCI 70-2 IV closure and can withstand harsh operating conditions. Thick (solid) seats for high speed, abrasive or corrosive applications.

The segmented V-notch ball has a high range and smooth throttling.

Choose between full ports and reduced ports to provide the right traffic for each application at a low cost.

Machined ISO 5211 top mount flange (VA series only).

Heavy duty stainless steel shaft with high strength and stiffness.

Multiple adjustable ring packing allows easy adjustment without removing valves or actuators.

The shaft bearing ensures the durability, smoothness and easy operation of the valve.

The split bodies are aligned.

Spline connections make the backlash between shaft and disc small. The control effect is good.
