VP40
Three way, open loop proportional pressure control valve with
directly actuated poppet seat driven by an external power
amplifier/drive electronics. Extremely robust, ideally suited to
mobile/on vehicle applications. Option for power amplifier/
drive electronics to be integrated in the solenoid plug.
