Information

Product Overview: 

LXHQ pneumatic regulating ball valve is driven by pneumatic actuator, combined with V-shaped ball core, slotted ball core or special flow channel ball core design, to achieve high-precision proportional regulation function. The valve not only has the advantages of simple ball valve structure, rapid opening and closing, small flow resistance and good sealing performance, but also has good linear regulation characteristics, can accurately regulate fluid flow, is an important regulating element in industrial automation process control, and is widely used in chemical, petrochemical, papermaking, electric power, metallurgy, food, medicine, water treatment and other industries.
