The IDEX Inline Inlet Check Valve, 15 psi, 1/4-28 Flat-Bottom (CV-3301) is a spring-actuated fluidic valve designed to manage directional flow and prevent backflow in compatible laboratory systems. It features a 0.020 in (0.50 mm) orifice, a 15 psi (1 bar) cracking pressure and a maximum pressure rating of 2000 psi (138 bar).
Key Features
- Spring-actuated one-way sealing, helping prevent backflow, upstream contamination and potential system damage
- 15 psi cracking pressure, equivalent to 1 bar for controlled valve opening
- 1/4-28 flat-bottom connections, with a female inlet port and male outlet port
- Compact 0.020 in flow orifice, equivalent to approximately 0.50 mm
- Maximum pressure rating of 2000 psi, equivalent to 138 bar
- Low 20 µL swept volume, limiting additional internal fluid volume within the flow path
- Chemically resistant wetted construction, incorporating PEEK, PCTFE, perfluoroelastomer, PTFE and stainless steel
- Broad 1/4-28 fitting compatibility, suitable for corresponding flangeless, Super Flangeless and VacuTight fittings
- Single-valve supply, provided as one complete inline inlet check valve
Benefits
- Protects upstream components by stopping unwanted reverse flow through the fluidic system.
- Supports reliable directional control in chromatography and laboratory liquid-handling pathways.
- Minimises added system volume through its compact orifice and 20 µL swept volume.
- Simplifies integration with commonly used 1/4-28 flat-bottom fluidic fittings.
- Provides chemical resistance across a broad range of compatible laboratory fluids.
