Features

SP Series Proportional Ball Valves

Chemline SP Series Proportional Ball Valve is designed for proportional (linear) flow control of chemicals or clean fluids. The ball is specially designed to provide linear characterized flow control 20 degree through 90 degree rotation of the handle. This valve is similar but not of the same design as other V-port ball valves. It offers excellent control and Cv values higher or similar to those of diaphragm valves. With a positioning electric actuator, this becomes an inexpensive control valve.
