Neles

The Neles product catalog covers product categories including actuators, ball valves, butterfly valves, globe valves, segmented ball valves, and valve controllers. Within the actuator range, the N1 Series uses a heavy-duty scotch-yoke design, while the B1 Series uses a pneumatic cylinder-operated rotary design. VB and the VD Series use pneumatic cylinder-operated and linear-stroke diaphragm-operated designs, respectively. Combined with the M Series manual worm-gear actuators, these products meet a range of mechanical drive requirements. The valve range includes full-bore modular M Series ball valves, seat-supported or trunnion-supported ball valves such as the X and 6D Series, butterfly valves including the BW and BWX metal-seated series and Neldisc L Series triple-offset butterfly valves, as well as cage-guided or guided control valves such as GB, AB, Omega, and RotaryGlobe ZX. During product selection, users should focus on fluid properties, system differential pressure, and the required precision of flow control.
