Double flanged butterfly valve ues the ductile iron materials with good casting performance, low cost, convenient production
Pneumatic actuator butterfly valve use pneumatic actuator more easy maintenance and good adaptability to the environment,the output power is large,and fast opening and closing speed.
Pneumatic Actuator Double Flanged Butterfly Valve
butterfly valve small in size, light and cheap, reliable in performance, simple in matching, and large in flow capacity. The butterfly valve especially suitable for occasions where the medium is viscous, containing particles and fibers. butterfly valves are widely used in industrial automatic control systems in light industry, petroleum, papermaking, chemical, teaching and scientific research equipment, electric power and other industries.
