A pneumatic actuator (100) is provided according to the invention. The actuator (100) comprises an actuator body (102) and a piston rod (108) extending from the actuator body (102). The piston rod (108) moves over an actuation span. The actuation span comprises a first stroke span that is traversed by the piston rod (108) at a first actuation speed and a second stroke span that is traversed at a second actuation speed that is substantially slower than the first actuation speed.
