electro-hydraulic actuator - self contained, glycol fluid, AC motor

[davefitz]

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.

their "Skilmatic" line is pretty functional and the price is really good. It is a UK Company with manufacturing in the UK and in New York state in the US.
