The Praher Valves range of lockable ball, butterfly and diaphragm valves permits the operator to secure the valve in either the open or closed position, with the aid of a padlock or similar locking device. In the case of the butterfly and diaphragm valves, the hand lever/wheel may be locked in open, closed or a variety of increments in between.
The ‘S4’ ball valves are rated to 16 bar and available in sizes from DN10 to DN100. The butterfly valves are available in sizes from DN80 to DN200 and the diaphragm valves from DN10 to DN125, while both are rated to 10 bar.
The ball, butterfly and diaphragm valves are also available with pneumatic or electric actuators, proportional controllers and position indicator switches if required.
