Description Series DDRRZ-70… proportional 3-way pressure-reducing cartridges are direct acting, spool-type, push-in cartridges and are available in sizes 2...5. They reduce the outlet pres sure in A as a function of the control current signal and inde pendently of the inlet pressure in P. In the initial position (solenoid de-energised) the inlet of the 3-way pressure-re ducing 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. Five pressure ranges are available. To accommodate a maxi mum operating pressure (inlet pressure) of pmax 100 bar, the “H” model must be used. With other models the maxi mum operating pressure is dependent on the pressure range. These 3-way pressure-reducing cartridges are pre dominantly used for reducing a system pressure in mobile and industrial applications. They are suitable for controlling larger directional valves, where they can be incorporated in the valve body or directly in the end covers, for example, and for controlling pumps and motors. All external parts of the cartridge are zinc-nickel plated according to DIN EN ISO 19 598 and are thus suitable for use in the harshest operat ing environments. For self-assembly, please refer to the section related data sheets.
