• Direct, to restrict system pressure • Can adjust pressure by controlling the current with the solenoid according to the characteristic curve • In the event of electrical failure, the restricted pressure is still within safety level (solenoid current > Imax) • External amplifying sub-plate mountinghas slope and valve calibration functions (separate order)
