The DRKE series shuttle valve is characterized by very high pressure load capacity and extremely low Δp. The 3-way shuttle valve shuts off whichever of the inlet ports A or B is at the lower pressure. Port C is thus always connected to the higher pressure.
The shuttle valve in ball-type design is very robust, extremely leak-proof and insensitive to contamination. The valve seat, ball, and housing are hardened. Sealing of the valve in the installation bore is achieved by a metallic sealing edge and a back-up ring. The valve is available in nominal size 04 (with rotor seal) and nominal size 08 (with O-Ring and back-up ring).
