Marwin Ball Valves: control valve
April 4, 2000
The 3000 Series control valve provides accurate control of gases, liquids, and slurries for linear or equal percentage flow, says the manufacturer. The valve is equipped with a characterized plate designed with two standard openings — slotted and V-style. Standard plate angles are 30, 60, and 90 degrees. Custom-designed plates with other angles or slots are available. The valve offers high- and low-flow control and excellent repeatability, the company says. It is available in 1/4- through 4-in. sizes. Marwin Ball Valves, 3170 Wasson Rd., Cincinnati, OH 45209; 800-628-2583; 513-533-7340; 513-533-7343 (fax).
