Low Pressure Rotary Shear Valves LLPR-Series

Valve head configurations up to 29 ports with channel sizes starting from 0.5mm.

LLPR-Serie rotary shear valves

Description

These high-precision rotary shear valves with channel sizes from 0.5mm to 1.5mm are suitable for the selection, distribution or injection of liquids in life science applications.

The fast-switching valve variant with rotation times from 100ms and channel sizes from 0.5mm are suitable for demanding applications where a very low internal volume and carryover volume is of crucial importance for the analytical process. Examples of this can be found, among other things, in microfluidics.

Materials in contact with media such as PEEK, UPE and ETFE offer high chemical resistance and biocompatibility, as well as a long service life.

Customer-specific versions of valve head configurations, fluidic connections or other wetted materials are possible.
