Miniature Fluid Control Valves: Multiport Switching, High-Pressure Injection and Flow On/Off Control

FOREACH offers rotary selector valves, high-pressure rotary valves and miniature diaphragm solenoid valves for IVD and analytical instruments. Use them to select fluid sources, switch reagent and wash paths, or open and close liquid flow. Selected high-pressure configurations support HPLC sample-loop loading, injection and venting.

MRV3 rotary valves offer 10-, 16- and 24-channel configurations with RS232/RS485 communication. The HP two-position, six-port valve has a maximum operating pressure of 25 MPa and an internal volume of 0.8 μL. SV10 solenoid valves include two-way normally closed, two-way normally open and three-way versions, with an operating pressure range of −75 kPa to 0.25 MPa. These are model-specific examples.

Select the valve around system pressure, residual-volume requirements, switching cycles, power-off state, port geometry and electrical interfaces. Wetted components and seals depend on the order configuration. Check their compatibility with reagents, samples, mobile phases and cleaning fluids before integrating the valve with pumps, tubing and fittings.
