Pressure Relief Cartridge Valve series DDPC-1L

Pressure [bar]


Flow rate [L/min]


Series DDPC-1L… cartridges are screw-in pressure-relief valves, nominal size 4 mm. They are direct-acting seat
valves. The mounting thread is the 3/4“-16 UNF pattern. The straightforward design delivers an outstanding price/ performance ratio and good pressure drop – flow rate characteristics. In order to obtain a good pressure adjustment over the entire pressure range, the total pressure range is subdivided into 7 pressure stages. A pressure stage corresponds to a certain spring for a settable maximum operating pressure. The cartridges can be fitted in the AL cavity and also in some 3/4“-16 UNF cavities from other valve manufacturers. The pressure is set by means of an adjusting screw or a hand-knob. To safeguard pressure settings, the adjusting screw can be sealed with a tamper proof cap.
