Chemline Plastics has introduced the SM Series Metering Ball Valve designed for fine linear flow control of chemicals or clean fluids such as water. The ball is solid with a graduated V-groove cut on the outside surface. Precise linear flow control is accomplished through the 0° to 180° rotation of the handle in 5° increments. The many fine flow-control applications include pressure washing systems, aquatic life support/fisheries research and many others. 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.
