This is a 3-way, spool type, normally closed, priority type, pressure compensated proportional flow control valve.
In the de-energized condition, flow is blocked from port 1 to the priority port 3 and all flow passes from port 1 to 2.
Energizing the coil will proportionally move the spool, opening a variable orifice from port 1 to 3, while excess flow passes to port 2.
An internal compensating spool ensures that the output flow at port 3 remains constant, regardless of changes in differential pressure between port 1 and 3 or pressure at the bypass port 2. Increasing the current to the coil will increase the priority outlet flow.
