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 in SM metering valves is solid with a graduated V-groove cut on the outside surface. Precise linear flow control is said to be accomplished through the 0° to 180° rotation of the handle in 5° increments.

Fine flow-control applications include pressure washing systems, and aquatic life support/fisheries research.

The series includes features such as full blocking design, double stem O-rings for safety, and 230 psi rating for PVC. Low stem torques are achieved through the company’s floating ball design and cushioned PTFE seats.

The valve is also bidirectional for precise flow control in both directions.

Product highlights include: ½ to 1 in. sizes; PVC or Polypropylene body; threaded, socket, butt, or ChemFlare ends; and EPDM or FPM O-rings.
