    SM Series Metering Ball Valves

    Chemline SM Series Metering Ball Valve is designed for fine linear flow control of chemicals or clean fluids. The ball is solid with graduated V-groove cut on the outside surface. Precise linear flow control is accomplished through 180 degree rotation of the handle. With a positioning electric actuator, this becomes an inexpensive control valve. If higher Cv values are required, refer to SP Series Proportional ball valves.

    ✓ Precise Linear Flow Control
    Provided by a special V-groove ball and wide handle travel (0 to 180 Degrees)
    ✓ High End Ball Valve Features
    Full Blocking design, Double Stem O-Rings for safety, and 230 psi pressure rated (PVC)
    ✓ Bidirectional
    Works with flow in either direction
    ✓ Low Stem Torques
    Due to floating ball design and cushioned PTFE seats
