ELECTRO-HYDRAULIC ACTUATOR

QUIFER ACTUATORS designed an electro-hydraulic actuator fail safety. This Actuator is an aluminium spring return actuator modified for to work as a hydraulic actuator, connected to a monophasic engine that works as a bomb with a hydraulic tank assembled.


DESIGNATION

KEH-AAA - Electro-hydraulic spring return

Where:

AAA- Specified the size of the actuators

ADVANTAGES


The actuator is designed to fail safety, if some reason you lose electrical power, close or open the valve to the position of fault by the springs.

The actuator only requires electricity for works, because it contains a tank where the oil builds up his performance.

El actuator has a compact design, and it’s connected through aluminium plates and not contains any pressure hydraulic conductivity, as the oil moves through the plates.

El actuator contains linking surfaces as per ISO 5211 and VDE/VDI.

The actuator can operate horizontally and vertically placed without making any modifications

Polyurethane coated for corrosion safety.
