Shuttle valves Type R2D with deepened plug

mounting cavity.

NB04 + NB10

General Description

Shuttle valves Type R2D have three operational ports A,

B and C. The valve shuts off whichever of the inlet ports

A or B is at the lower pressure, with no leakage. Port C

is thus always connected to the higher pressure.

The preferred mode of mounting is the installation in

manifold blocks, which can be equipped with several

valves depending on the hydraulic circuit for the specific

application. Each valve can be connected to each other

in the manifold block.

These valves are available in two sizes:

04 and 10.

Benifits

• high pressure rating

• virtually zero leakage

• compact construction

Sizes

• Maximum operating pressure: 420 bar

• Nominal flow at ∆p = 5 bar :

- NB 04: 6 L/min

- NB 10: 80 L/min
