General features

Design:
Proportional pressure regulator with proven moving coil and flapper/nozzle
technology, built-in volume booster and coated glandless spool.
The regulator has a single loop, electric feedback from the outlet pressure.
Proportional valve for industrial use with 5 μm built-in filter protection.
