HK59-D-F Pneumatic Flanged Butterfly Valve Series
Benefits Of Pneumatic Flanged Butterfly Valves:
The advantages of pneumatic flanged butterfly valves are good sealing performance, zero leakage and long service life. Provide you with sustainable and reliable fluid solutions. Flanged butterfly valve can be divided into soft sealing butterfly valve and hard sealing butterfly valve according to the material of the seal to meet the needs of different working conditions. A variety of styles are available for you to choose from, providing you with flexible solutions.
Pneumatic actuators with positioners can receive or feedback signals and are compatible with various control systems to meet your remote control purposes.
