Solenoid Valves: On-Off Control of Washing and Dispensing Branches
In on/off-valve configurations, coordinate supply and drainage with pump and wash-head timing. Determine independent channels, common manifolds and simultaneous demand from the actual assembly.
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 solenoid valves. Identify every port, current source, receiving destination and isolated branch. Check connections during aspiration, delivery, washing, maintenance and power loss. Match valve actions to the pump's permitted operating states.
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 |
|---|---|---|
| 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
Assess differences in delivered volume between wells, residual liquid after washing and the complete plate cycle. Preserve well identities.
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.
Multiport selection does not provide independent simultaneous channels. Validate washing through both liquid handling and retention of the required solid phase.
