Linear electro-hydraulic solution

Challenge

Operate a process valve with 120 mm stroke.

Solution
EHLA#135/95-130 composed by a double acting hydraulic linear actuator (HLA) controlled by a microprocessor-based Digital Hydraulic Actuator Positioners (DHAP).

• The highest precision of process valve position control is guaranteed by an Electric Control Panel equipped with Biffi ECU 1000 electronic positioner.
• The ECP with local operator interface and diagnostic function monitors the correct operation of the actuator and generates alarms in case of failure.
