Multiport Rotary Valves: Selecting Reagent Sources and Dispensing Destinations
Establish the current dispensing connection in multisource or multioutlet configurations, coordinated with drive operation and container records. Treat bottle changes, source switching, priming and shared-volume displacement as separate steps.
MRV3 selects sources or destinations and requires a port-state diagram and shared-volume budget. Port count indicates routing options; confirm pressure in each state and independent simultaneous supply requirements separately.
Solenoid valves: dispensing-outlet shutoff
At outlets using on/off control, coordinate starts and stops with the supply pump and verify the power-off state. Check retained droplets, post-stop dripping and delivered volume at the receiving vessel.
Solenoid valves control branches according to actual ports, flow direction, differential pressure and power-off state. Check opening/closing order with pump commands; inspect shutoff leakage and shared residue separately.
Define connections using the instrument's port-state diagram
This page covers multiport rotary and solenoid valves. Mark each port, current source, receiver and isolated branch, checking connections during aspiration, delivery, cleaning, maintenance and power loss. Valve selection must match conditions permitting drive actions.
Include renewal of shared segments after switching in the sequence
After source switching, shared tubing may retain the previous composition. Record volume and arrival delay from the new source to the receiver, and measure residue and recovery for the actual worst-case switching combination. Confirm port positioning and arrival of new liquid separately.
Translate actual branch conditions into configuration requirements
| Condition | To confirm |
|---|---|
| Connections and pressure | Provide port diagrams and pressure conditions for all operating, cleaning and shutdown states. |
| Shared volume | Identify residue locations after source changes, flushing volumes and discharge destinations. |
| Control and isolation | Check valve-position feedback, pump actions, shutoff leakage and permitted power-off states. |
Compare product configurations by the roles on this page
| Product | Configuration option | Conditions to verify |
|---|---|---|
| MRV3 multiport rotary valve | Multiple-source selection | Compare 10-, 16- and 24-port options and port diagrams; verify high-pressure suitability separately |
| SV10 solenoid valve | On/off control or branch selection | Check normal state, differential pressure, flow direction and duty cycle; high-pressure tasks require a separately suitable configuration |
Confirm product roles in actual operation
Include first, middle and last batch doses, recovery after bottle changes, and extended operation with the actual medium.
Do more valve ports mean more channels can supply liquid simultaneously?
Check port connection structure and drive configuration. The number of selectable sources, independent paths and simultaneous-operation capability are different conditions, determined by actual connections in each state.
Repeated dosing and continuous supply are different modes. Valveless metering also requires validation with the actual medium and operating conditions.
