BR/V Series Pneumatic Actuator
BR/V series is an rotary actuator with internal rack and pinion structure. The cylinder is designed according to ISO5211 or DIN3337 standard.
Cylinder diameter from 52mm~400mm optional, Including double acting and single acting. A singleacting actuator is formed by adding standard springs to the double-acting cylinder. The number of springs can be determined according to the demand torque.The BR/V series can be applied to pneumatic butterfly valves and ball valves in power plants, petrochemical plants and pipeline projects.
Technical data & Main features:
- Cylinder bore: 42 ~ 330 mm.
- Torque: 20~ 10000 Nm.
- Stroke: 90 °± 5°.
- Cylinder operating pressure: maximum 8 bar.
- Cylinder operating temperature: -20~150 ℃.(other temperature can be customized)
- Failure protection: fail freeze / fail open / fail close.
- Tubes and fittings: copper or stainless steel.
- Double acting and single acting.
- According to ISO5211 , DIN3337, VDI/VDE3845 and NAMUR standard.
- Control system can be designed according to the requirement.
Double acting actuator
CCW
Port A pressurize, port B exhaust. Compressed air pushes the piston outward, and the cylinder shaft rotates counterclockwise.
CW
Port B pressurize, port A exhaust. The compressed air pushes the piston to the middle, and the cylinder shaft rotates clockwise.
Single acting actuator
CCW
Port A pressurize, port B exhaust. The compressed air resists the spring force and pushes the piston to move outward. The cylinder shaft rotates counterclockwise.
FAIL CW
When cylinder loses pressure, Springs push the piston to the middle and the cylinder shaft rotates clockwise.
