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 de-energized state, pressure and duty cycle
Specify maximum actual pressure, medium, individual and sustained energization times, and allowable leakage. Confirm unpowered state, installation direction and thermal effects for the model and operating environment.
| Condition to compare | Information required | Selection affected |
|---|---|---|
| Power-loss state | Normally open, normally closed and liquid destination during faults | Match the system's permitted power-loss behavior |
| Opening and closing load | Actual differential pressure, medium and flow direction | Check drive and sealing requirements |
| Energization cycle | Pulse duration, duty cycle and continuous energization | Evaluate thermal state and long-term actuation |
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 |
|---|---|---|
| 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 |
Coordinate valve opening/closing with pump startup
Coordinate valve opening and closing with pump startup to avoid operating toward the wrong destination or a closed outlet. On communication or power faults, the controller should preserve container and completed-action records.
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 repeated operation using the actual medium
Check opening, closing, leakage, sustained energization and power-loss response at actual pressure with the actual medium. After power returns, verify the path before permitting liquid motion.
| Validation scenario | Measurement or observation | Interpretation and action |
|---|---|---|
| Operation with the actual medium | Compare switching, sealing and continuous operation | Unloaded actuation does not establish performance with liquid |
| Recovery after power loss | Check valve state and pump coordination | Confirm source and receiving end before restoring supply |
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.
