Linear actuator
Product Overview
Spirax Sarco BVA300 series pneumatic rotary actuators are drive units specifically designed for various Spirax Sarco ball valves, widely used in multiple industrial applications. This series features bi-directional travel stops for precise 90º±5º rotation, paired with the new BVL-X coupling (with extended stem) to ensure reliable connection and efficient transmission with Spirax Sarco ball valves.
The actuators are compatible with three categories of Spirax Sarco ball valves:
- Three-piece ball valves: M10F ISO, M10Hi ISO, M10HPi ISO, M10HTi ISO, M10Pi ISO, M10Si ISO, M10Ti ISO, M10Vi ISO, M15i ISO, M70i ISO and M80i ISO
- Two-piece ball valves: M31S ISO, M31V ISO, M33F ISO, M33H ISO, M33HT ISO, M33S ISO, M33T ISO and M33V ISO
- One-piece ball valves: M21Fi ISO, M21Hi ISO, M21HTi ISO, M21Si ISO, M21Ti ISO, M21Vi ISO, M40Fi ISO, M40Hi ISO, M40HTi ISO, M40Si ISO, M40Ti ISO, M40Vi ISO and M45i ISO
Key Advantages
