Pressure Reducing Cartridge Valve DDRA-7L

Pressure [bar]

315

Flow rate [L/min]

70

Series DDRA-7L… screw-in cartridges are size 10, high performance 3-way pressure-reducing valves with an M27x2 mounting thread. They are direct acting and have a spool-type design. The straightforward design delivers an outstanding price/performance ratio and good pressure/ flow ratings. The valves control the required secondary pressure in port 1 to the value set with the pressure adjustment, and independently of the inlet pressure in port 2. In control mode, the connection 2→ 1 opens until the pressure in port 1 reaches the preset level. If the pressure rises above the preset level, the control spool opens the 1 → 3 connection until balance is restored. These 3-way pressure-reducing cartridges function as full-flow pressure relief valves from port 1 → 3 as soon as the reduced pressure rises above the valve pressure setting.
