SM Series Metering Ball Valve


Designed for fine linear flow control of chemicals or clean fluids, the SM Series Metering Ball Valve is solid with a graduated V-groove cut on the outside surface. Precise linear flow control is accomplished through the 0 to 180-deg. rotation of the handle in 5-deg. increments.


The SM Series includes high-end ball valve features such as full blocking design, double stem O-rings for safety, and 230 psi rating for PVC. Low stem torques are achieved through Chemline’s floating ball design and cushioned PTFE seats. This valve is also bidirectional for precise flow control in both directions. A positioning electric actuator makes the SM Series a cost-effective control valve.
