Pneumatic Actuators
eDART Actuator - eDART Actuators have proven themselves over the years as an effective, reliable and cost effective actuator. eDART's unique design eliminates the use of tiebars which reduce the size and weight of the actuator. The biased spring options - which allow for fail action but are piped Double Acting for superior control – are 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.

Double Acting |
| These standard actuators are piped top and bottom and allow for superior control in modulating applications. | |
| Biased Fail Extended | |
| This option on the eDART actuator allows for a fail action but still be piped double acting for superior control. However, the valve needs to be flow-over the plug to close in the fail position - the spring assists in overcoming friction. | |
| Heavy Duty Fail Extended | |
| On the Heavy Duty range of springs, the spring is sized to close the valve without assistance from the flow direction. | |
| Heavy Duty Fail Retracted | |
| On the Heavy Duty range of springs, the spring is sized to close the valve without assistance from the flow direction. |
