BVA300 Series Pneumatic Actuators for use with Spirax Sarco Ball Valves
Description The BVA300 series are pneumatic rotary actuators which automate Spirax Sarco ball valves in a wide range of industrial applications. BVA300 actuators are provided with bi-directional travel stops that allow a rotation of 90 ° ±5 ° . Linkage is made with the new BVL_X kits with extended stem (not available for M10MVi and M10MSi models. For more details, see page 7). Pneumatic actuated ball valve range: Page
