The Cole-Parmer VapLock Valve, 6-Position, 0.032 Inch, 24 VDC (EW-12021-59 / 12021-59) is a normally closed solenoid mixing valve with a PTFE body and PTFE diaphragm. Its six-position configuration supports the mixing of selectable inlet streams into a common outlet, while reversed flow enables selection, diversion and stream-splitting functions.
Key Features
- Six-position flow configuration, allowing individual inlet streams or combinations of inlets to be selected
- Compact 0.032 inch orifice, supporting controlled fluid routing with minimal dead volume
- Chemical-resistant PTFE body, suited to fluid paths involving demanding media
- PTFE diaphragm construction, maintaining chemical resistance across the wetted valve assembly
- Normally closed solenoid operation, keeping the flow path closed until the selected position is energised
- 24 VDC electrical input, providing the specified operating voltage for system integration
- Maximum operating pressure of 20 psi, defining the verified pressure limit for the valve
- Service life above two million cycles, supporting repeated automated valve actuation
- Low-power solenoid design, helping minimise heat generation during operation
- Prewired electrical connection, supplied with 15 inch, 26-gauge PTFE-coated lead wires
- Flexible mixing control, allowing any combination of selected inlets to feed the common outlet
- Reversible flow functionality, enabling selection, diversion or splitting from a common inlet to one or more outlets
Note: The resulting outlet composition depends on the pressure and fluid viscosity of each selected inlet stream.
Benefits
- Supports automated handling of chemically demanding fluids through a PTFE wetted flow path.
- Consolidates mixing, selection, diversion and splitting functions within one compact valve configuration.
- Reduces unwanted retained fluid between process changes through the minimal-dead-volume design.
- Improves long-term process reliability through a solenoid rated for more than two million operating cycles.
- Limits heat transfer into sensitive fluid systems through low-power valve operation.
- Simplifies electrical installation through the factory-fitted PTFE-coated lead wires.
