Pilot Operated Pressure Reducing Valve Series R4R (Denison)
Catalogue HY11-3500/UK
Characteristics Pilot operated pressure reducing valves for in-line mounting series R4R have a similar design to the subplate mounted R4R series. For single functions - where no manifold blocks are used - 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 • Pilot operated with manual adjustment • Normally closed to avoid undesired motion • 2 interfaces - L-body (R4R06-G¾", R4R10-G1¼") - T-body (R4R03-G½", R4R06-G1") • 3 pressure stages • 3 adjustment modes - Hand knob - Acorn nut with lead seal - DIN lock • With optional vent function
