What do these products do in this instrument?
Multiport rotary valves: analytical supply and maintenance routing
Connect the current sample, wash liquid or maintenance outlet in selector-valve wastewater paths, coordinated with drives and analytical states. After backflushing or bypass operation, confirm sealing and fresh-sample replacement.
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: flushing and backflush branch shutoff
Open or close maintenance branches in applicable on-off configurations, coordinated with pumps and drainage destinations. Define flow direction, differential pressure and unpowered states, with interlocks to prevent maintenance liquid reaching the analytical interface.
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
Validate delivered-sample representativeness, target recovery and renewal after washing and restart.
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.
Water-test specifications do not establish suitability for complex wastewater. Filtration must follow the defined target fraction.
