The 1/4-28 Upchurch Scientific Inline Check Valve’s spring-actuated sealing pattern eliminates back flow, helping to prevent upstream contamination or damage. In addition, the unique design of this product eliminates the additional tubing cuts and connections required to install conventional inline check valves.
The Quick-Stop Luer Check Valve is designed to provide inline luer connect/disconnect convenience without the mess and hazard of spills. Just connect the valve assembly to your inline tubing using standard 1/4-28 flat-bottom fittings. The check valve is automatically opened once the luer connection is engaged, allowing flow in either direction. Disconnecting the luer union causes the check valve to close.
Upchurch Scientific cartridge style Inline Check Valves are designed to limit flow to one direction. These assemblies withstand system pressures of 1,000 PSI (69 bar). The cracking pressures are 1.5 PSI (0.1 bar) for the CV-3001 and 3 PSI for the CV-3011. Tolerance on the cracking pressure for CV-3001 is ± 0.5 PSI (0.03 bar) and ± 1.5 PSI (0.1 bar) on CV-3011.
