LXHQ pneumatic switch butterfly valve

Product Overview: 

LXHQ pneumatic switch butterfly valve is a kind of automatic valve which uses compressed air as power source and uses pneumatic actuator to drive the butterfly plate to rotate 90 ° to realize rapid opening and closing of fluid. The utility model has the characteristics of compact structure, rapid operation, reliable sealing, wide application range and the like, and is suitable for the on-off control of liquid, gas, steam and other media in a pipeline system. Widely used in water treatment, petrochemical, power, pharmaceutical, food, paper, environmental protection and other industries.
