The E range of actuators is suitable for on-off (isolating) or continuous (modulating) duty and can readily interface with a computer, programmable logic controller or conventional electrical control gear. Actuators can be made to respond to either analogue or digital control signals and can be supplied with solid state adjustable set points to correspond to desired positions of travel, mechanical limit switches, transducers, potentiometers, starters, position controllers and continuous position indication.
The versatility of hydraulics enables simple adjustment of speed and thrust/torque whilst various valve combinations enable the piston rod/output rod to be either locked or unlocked when at rest. Manual operation can be provided via a handpump whilst emergency power operation utilising either disc springs or accumulators can be incorporated as required.
