The PWK06020V is a normally open,
direct-acting, proportional ow control
valve.
It is non-compensated and its function is
to smoothly control the ow from port 1 to
port 2. The energization of the coil reduces
or increases an orice cross-section and
thus controls the ow. Together with a
pressure compensator the proportional
ow control valve can be used as a 2-way
ow regulator – for example when required
to lift/lower variable loads at the same
velocity.
