Pneumatic Scotch Yoke Actuators
Pneumatic Scotch Yoke Actuators are designed to operate in the harshest, most demanding industrial applications and environments where functionality and reliability are required throughout the complete cycle of valve automation.
Predominantly used for larger-sized Ball & Butterfly Valves the Scotch Yoke Actuator offers 90° quarter turn, on-off operation by converting linear movement to rotary action through the internal driving cylinder and scotch yoke mechanism with high start and end torque output up to 60,000NM.
This, in turn, transmits power continuously and precisely to operate the Ball or Butterfly Valve.
The Good Supplier Scotch Yoke Pneumatic Actuator is a compact, lightweight and economical unit bringing reliability and low maintenance to industries where it is needed most and offering long, uninterrupted service.
Available in both Spring Return & Double Acting units setup can be arranged in either the fail-safe open or closed positions, returning the actuator and valve position to the required safety location in the event of a power failure.
The benefits of Pneumatic Actuators stem from both their overall safety and reliability. First of all, since Pneumatic Actuators can convert energy into motion without ignition or electricity, they’re highly sought after in situations where sparking and combustion cannot be tolerated. In these settings, compressed air can be stored and used in an efficient and repeatable manner that poses no fire risk.
Features & Benefits
⦿ A compact, lightweight, economical, and reliable design provide long-lasting effective service
⦿ Higher breakout torque from zero position makes this actuator the perfect solution for the soft seated ball and butterfly valves where 75% of the torque is generated by the seat
⦿ Increased torque for spring return position
⦿ Fail-safe open or close setup available
⦿ Emergency manual override features including jackscrew, hand pump, and gear operation
Since Pneumatic Actuators that don’t rely on combustion can be manufactured easily and are relatively simple devices, they are also extremely durable, have minimal maintenance needs, and offer a long operational life when used correctly.
