Locate the source, drive and receiving position for this task
Define all ports, valve states, pressures in each state, shared volume and displacement volume. Follow the diagram to confirm liquid contact, pressure and destination before assigning drive and connection roles.
Define the port map and pressure states before selecting a model
List ports, media, actual pressures, passage dimensions, shared volume and switching time. Compare the published 10-, 16- and 24-port MRV3 configurations for source selection. Confirm high-pressure injection and power-off isolation requirements separately.
| Condition to compare | Information required | Selection affected |
|---|---|---|
| Port connectivity | Source and outlet for every valve position | Define every switch with a state diagram |
| Pressure and medium | Pressure and contact liquid in each state | Separate low-pressure selection from high-pressure switching |
| Shared path | Dead volume, displacement and switching time | Include residue control in the cycle |
Compare product options against task requirements
The following candidate options match this page's responsibilities. Compare them against the operating conditions described, then check capacity, materials and interfaces on the product pages. Card images show representative configurations; suitability must still be confirmed at actual operating points and by application results.
| Product category | Corresponding role | Confirm before selection |
|---|---|---|
| MRV3 multiport rotary valve | Multiple-source selection | Compare 10-, 16- and 24-port options and port diagrams; verify high-pressure suitability separately |
| HP high-pressure injection valve | Pressurized injection-path switching | Check port pressures and sample loops in loading, injection and other states |
| 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 |
Interlock valve position, pump action and destination
Interlock valve position, pump actions and receiving direction. After positioning, determine whether the shared path needs flushing. Include maintenance and fault states in the diagram.
Action records should link commands, valve or interface states and actual received results. When raw material, container or sample identity changes, reconfirm shared paths and conditions permitting the next step. Completion of drive movement alone does not replace task acceptance.
Validate connectivity, leakage and flushing separately
Check connectivity, leakage, displacement, pressure recovery and residue in each state. A multiport valve's port count does not establish independent parallel channels or high-pressure suitability.
| Validation scenario | Measurement or observation | Interpretation and action |
|---|---|---|
| Connectivity and sealing | Check flow direction and leakage in each state | A valve-position signal does not replace fluid-path validation |
| Source switching | Assess recovery with the most challenging liquid combinations | Determine displacement conditions from residue results |
Record test medium, configuration, installed path and operating sequence; present routine operating points and boundary results separately. Calculations support design discussions, component documentation checks models, and installed measurements confirm the actual task.
After an abnormality or maintenance, first identify which segment needs recovery
Mispositioning, shared-path residue or abnormal switching pressure can affect the next task. Stop pumping and check ports, then flush again after restoring the correct state.
Retain current source, container identity, completed actions, valve or interface state and actual receiving information. Use the table to locate the stage that changed before deciding to retry, continue or restart. After recovery, recheck the relevant operating point before returning an uncertain action to the automatic cycle.
