Pneumatic and motorized ball valves are used for flow control of liquids and gases with diameters from DN15 to DN300 (1/2 "to 12") and pressure classes PN16 to PN40 (ANSI150 to ANSI300).
The valves, designed as 2 - way or 3 - way, stand out with their low pressure loss and their ability to be used with partially particulate fluids thanks to their design that does not create an obstacle to flow. Ball valves which provide easy disassembly and maintenance with its simple construction, can serve for a long time. For this reason they are prefered in many industrial and installation applications.
Pneumatic and motorized butterfly valves are designed for flow control of liquids and gases with diameters from DN50 (2 ") to DN2000 (80") and pressure classes PN16 to PN40 (ANSI150 to ANSI300).
