SM Series Metering Ball Valves ½" to 2" in solid plastics are now available from Chemline Plastics. They are designed for fine linear flow control of chemicals or clean fluids through 180o rotation of the handle. The valves feature a solid ball with a special V-groove cut on the outside surface.
Other features include union ends, full blocking design, double stem o-ring for safety and Teflon seats. The seats have elastomer cushions to provide low stem torques and automatic compensation for seat wear and expansion. The all-plastic construction (PVC or PP) offers high chemical resistance at low cost.
Pressure rating for PVC valves is 230 psi; PP is rated at 150 psi. True Union socket end connections eliminate leakage problems common with threaded body valves. SM Series is available with an electric actuator with onboard positioner, making it an inexpensive electrically actuated proportional (linear) control valve.
Chemline SM Series Metering Ball Valve is designed for fine 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° rotation of the handle. With a positioning electric actuator, this becomes an inexpensive control valve.
