Rotary Shear Valves for Diagnostic & Analytical Instruments

Keyto rotary shear valves switch between fluid paths in medical, diagnostic and analytical instruments. Explore normal-pressure and high-pressure designs for applications that require controlled routing of samples, reagents or other process fluids.

Compare port counts, switching positions, internal volume and wetted materials to match your fluid circuit. The required pressure and routing sequence help determine which valve family to evaluate.
