The actuator product range offered by Large Actuator have proved themselves over many years in the field to be reliable and cost effective. The unique rolled cover tube design eliminates the tie bars which reduces the size and weight of the actuator. The Piston has a double O-ring plus continuous PTFE guide strip.

Furthermore, the feedback system for the positioner is engineered to give linear response to the valve position and the biased spring options allow for fail action but are piped Double Acting (DA) for superior control – specifically designed to be used on modulating control applications.
