What do these products do in this instrument?
Multiport rotary valves: selecting shared fixed-path resources
Connect actual sources and receiving stations to the shared metering path, coordinated with task resource locks and port states. Include valve position and shared-section renewal in operating and maintenance procedures.
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: branch isolation and state interlocks
Open or close branches equipped with on/off valves, coordinated with supply and waste-removal actions. Define destinations under power loss and abnormal conditions, and verify that isolation is achieved.
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. |
| Operation | Specific operating conditions |
|---|---|
| Fluid-path management | Task state, sample or vessel identity, concurrent resources, interlocks and restart |
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 |
Explore specific operating and validation tasks
Fluid-path management
Define resource conflicts for pumps, valves, stations and waste handling. Sequential and concurrent actions should follow the same state diagram. If confirmation is lost, preserve sample identity and completed-step records.
Confirm product roles in actual operation
| Operation | Measurements and observations | Priority checks |
|---|---|---|
| Fluid-path management | Test concurrent operation, limiting states and complete fault recovery; verify that identities, cumulative quantities and records match actual actions | Resource conflicts, communication loss or mismatched identities can cause delivery to the wrong destination or repeated dosing. |
Validate concurrency, restart after interruption and record traceability to prevent sample misassignment or duplicate dosing.
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.
Connectable modules are not automatically plug-and-play. Recovery actions must match the current liquid and sample state.
