4 x 4 Pneumatic Actuators
Brand: Sharpe ValvesSharpe® 4x4® Pneumatic Actuators have four pistons. 
With twice as many pistons applying torque to the pinion versus a conventional rack & pinion actuator with two pistons, the Sharpe® 4x4® pneumatic actuator generates the same output torque as a conventional rack & pinion actuator in a much smaller and lighter weight design.
