EVHCO80LS

EVHCO Low Current On/Off Actuation

The EVHCO is the latest electrohydraulic on/off
actuator offering to join ECO80LS portfolio.

The EVHCO provides the advantage of economy and
lower power consumption yet provides the same
form fit and function as earlier EVHCO actuators.

The EVHCO is now matched to a new family of main
spools which ensures the best response time at the
low energy levels.
