TYPE DBETR

This valve regulates pressure in proportion to the electrical command value. The valve consists basically of a housing, proportional solenoid with inductive positional transducer, valve seat and valve poppet. Pressure is set by adjusting the command value potentiometer (0 to 9 V). Adjusting the command value causes tensioning of the compression spring via the electronic controls and the proportional solenoid. Tensioning of the compression spring, i.e. the position of the spring plate, is determined by the inductive positional transducer. Any deviations from the command value are corrected by the closed loop positional control. The use of this principle eliminates the effect of solenoid friction.
