Valve and pressure regulatorThe pressure control unit and servo pressure regulator compensates for pressure fluctuations in the supply network. This ensures a constant volumeflowatconstantinjectorpres-sure. The servo regulator regulates the nozzle pressure at the valve outlet, dependent on the vacuum generated, towards zero.
Solenoid valvesSolenoid valve to EN 161, Class B. DC coil, protected against voltage transients.
