S&S V-100 VBall wafer-style rotary control valves utilize a standard ball with a triangular-shaped wedge. Available in 2-inch through 8-inch, they combine precision, accuracy, and control over a full 90° of rotation, functioning as an excellent valve for both throttling control and on/off service and with various actuators. The valve design closes against one of several available ball seals with a shearing action. The S&S V-100 is a flangeless design and allows the valve body to fit between two existing pipeline flanges. The flow characteristic is modified by equal percent, with regular (forward) flow into the convex side of the V-ball. Bi-directional flow is into either side of the V-Ball; TCM ball seal, metal ball seal, or flow ring. Typical actuators used are the pneumatic spring, diaphragm rotary actuator, and the pneumatic piston rotary actuator. Mounting of these actuators can be on the right-hand or left-hand side viewed from the forward flow inlet.
