EHi Steering Valve
Danfoss Electrohydraulic In-line Steering Valve (EHi) is
intended for off-road use. The EHi is designed for easy
integration in new vehicles, as well as upgrading
existing vehicles.
EHi with PVED-CLS actuator module form a fail-safe
steering valve, category 3 according to ISO 13849-1.
EHi fitted with PVED-CLS actuator, as well as a full
steering subsystem specification, has a 3rd party
certification available.
The EHi is a flexible alternative to Danfoss OSPE, for
vehicles where space around the steering unit is
particularly limited.
The EHi may be applied for fail-safe Steer-by-Wire
applications, joystick or mini wheel for slow moving
vehicles. Four-wheel steering, the EHi may be applied
for steering the rear axle, for vehicles where fail-safe
operation is acceptable.
