Pilot Operated Sequence Valve
Series R5S
R5S UK.INDD CM 02.08.11
Characteristics
Pilot operated sequence valves series R5S 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.
Features
• Pilot operated with manual adjustment
• 3-port body with SAE61 flange
• 3 sizes (SAE ¾", 1", 1¼")
• 3 pressure stages
• 2 adjustment modes
- Hand knob
- Acorn nut with lead seal
• Optional with vent function (on request)
