The SV10-P-3 is a miniature 2-position, 3-way diaphragm solenoid valve with a rocker diaphragm design. Its compact internal structure and low dead volume help reduce retained liquid. Switching the common port between the other two ports provides precise flow-path control for reagent supply and wash-fluid switching in automated sampling equipment, medical analytical instruments and laboratory liquid-handling systems.
The manifold-mount design and PEEK base plate allow multiple valves to be integrated on one fluidic manifold, bringing reagent branches and wash channels together. EPDM, FKM or FFKM diaphragms and matching O-rings can be selected for the reagents and wash fluids. When supply and washing share a line, use the actual internal volumes of the valve and tubing to assess system hold-up volume and determine the required wash-fluid volume.

FOREACH SV10 3-way miniature solenoid valves use a rocker diaphragm to switch a common port between two other ports. They select reagent or wash-fluid connections in automated equipment.
A 3-way valve can connect a common line alternately to reagent and cleaning fluid. After the reagent step, switch to the wash connection and use the pump to flush the shared tubing.
Set wash volume and repetitions according to the fluids, tubing length and acceptable residue, and check the result using the actual cleaning cycle.
Identify the shared line and the two paths to be selected. Check which ports connect with power applied and removed, then coordinate valve switching with the pump sequence.
Use the base-mounted version when combining valves on a fluidic manifold. Choose threaded connections for tube fittings, or barbed connections for flexible tubing.
Plan access for installation, tubing replacement and wiring. The three connection styles serve different layouts while retaining the same choices of 2-way or 3-way function.
Describe which liquid must flow at each step and what should happen when power is removed. Include the connection drawing, fluids, pressure, temperature, supply voltage and installation space.
Connect the common port to the shared line and the other ports to the two paths to be selected. Coordinate switching with the pump and equipment program. Three ports describe the connection arrangement; they do not mean three simultaneous flows or proportional mixing.
Match the valve function, connection, wetted materials and voltage to your equipment.
