electro-hydraulic actuator - self contained, glycol fluid, AC motor
(OP)
Some years ago I recall seeing and article which describde a self contained electro hydraulic valve actuator which used an AXC motor drive for the pump and water-glycol for the hydraulic fluid. I recaall it was made in the UK. However, I have not recently found any vednors which offer the same technology. \
Can anyone suggest a vendor of such actuators? We need 12 total, actuator force = 3500 lbf, 3.75" max stroke, stroke period of less than 2 sec, modulating service.

although its been a while, if you are still interested in this, try
