Heavy Duty Fail Retracted Pneumatic Actuator (with Mounting)
eDart Actuator - eDart Actuators have proven themselves over the years as an effective, reliable and cost effective actuator. Our unique design eliminates the use of tiebars which reduce the size and weight of the actuator. Our biased spring options allow for fail action but are piped Double Acting for superior control – specifically designed to be used on modulating control applications. On actuator mounting the feedback system is modelled to give linear response to the valve position.
