ECS2 Electrohydraulic spool actuator
The ECS2 is a proportional, hydraulically controlled spool
actuator with spring centring to the neutral position. It is
intended for remote control using an IQAN, for exam-
ple. Pilot-pressure oil is passed to the spool actuators
through internal ducts in the valve. This means that only
the electric cables from the control system to the pilot
solenoid valve needs to be connected externally.
Control current for 12 V
Breakaway min 570 mA
Fully actuated max 1250 mA
Control current for 24 V
Breakaway min 290 mA
Fully actuated max 650 mA
Suitable with PWM signal.
EC2 The EC2 is the same as ECS2, but with manual override.
Note: Read the information about manual override for
EC2 later in the catalogue.
