Characteristics
Pilot operated pressure reducing valves for in-line mount-
ing series R4R have a similar design to the subplate
mounted R4R series. For single functions ā where no
manifold blocks are used ā the valves can be directly
placed in the pipework.
The valves are available with 2 ports (L-body) or with 3
ports (T-body).
Features
ā¢ī Pilot operated with manual adjustment
ā¢ī Normally closed to avoid undesired motion
ā¢ī 2 interfaces
- L-body (R4R06-GĀ¾", R4R10-G1Ā¼")
- T-body (R4R03-GĀ½", R4R06-G1")
ā¢ī 3 pressure stages
ā¢ī 3 adjustment modes
- Hand knob
- Acorn nut with lead seal
- Cylinder lock
ā¢ī With optional vent function
