R5S Series Sequence Valves
Series R5S pilot operated sequence valves have a similar design to the subplate mounted R4S series. The SAE flanges allow to mount the valve directly on the inlet flanges of actuators or outlet flanges of pumps to achieve a very compact design. The R5S is pilot operated with manual adjustment, 3-port body with SAE61 flange, 3 sizes, 3 pressure stages, and 2 adjustment modes.
