Pilot Operated Pressure Reducing Valve
Series R5R
R5R UK.INDD CM 02.08.11
Characteristics
Pilot operated pressure reducing valves series R5R have
a similar design as the subplate mounted R4R series. The
SAE ļ¬anges allow to mount the valves directly on the inlet
ļ¬anges of actuators to achieve a very compact design.
Features
ā¢ Pilot operated with manual adjustment
ā¢ Normally closed to avoid unintended motion
ā¢ 2-port body with SAE61 ļ¬ange
ā¢ 3 sizes (SAE Ā¾", 1", 1Ā¼")
ā¢ 3 pressure stages
ā¢ 3 adjustment modes
- Hand knob
- Acorn nut with lead seal
- Key lock
ā¢ With optional vent function
ā¢ Flow direction B Ā® A
