Pressure Reducing Proportional Cartridge Valve DDRRZ-7080

Pressure [bar]


Flow rate [L/min]


Series DDRRZ-70… prop. 3-way pressure-reducing cartridges are direct acting, spool-type, push-in cartridges and are available in size 4. They reduce the outlet pressure in A as a function of the control current and independently of the inlet pressure in P. In the initial position (solenoid de-energised) the inlet of the 3-way pressure-reducing cartridge is shut off and the outlet is connected to tank (port A → T). In control mode, the connection P → A opens until the pressure in port A reaches the preset level. If the pressure rises above the preset level, the control spool opens the A → T connection until balance is attained. Two pressure ranges are available. To accommodate a maximum operating pressure (inlet pressure) of pmax 210 bar, the “H” model must be used. With other models the maximum operating pressure is dependent on the pressure range. These 3-way pressure-reducing cartridges are predominantly used for reducing a system pressure in mobile and industrial applications
