Connect these Upchurch Scientific® Inline Check Valves to any 1/4-28 flat-bottom port. Then thread your 1/4-28 flat-bottom fitting into the check valve to connect the tubing. Once installed, the spring-actuated sealing system eliminates back flow, preventing 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.
At a low cracking pressure of only 3 psi (0.21 bar), our CV-3315 and CV-3316 Check Valves are well suited for syringe-pump and vacuum systems. The cracking pressure of our CV-3301 and CV-3302 Check Valves is 15 psi (1.0 bar). All four of these valves are constructed of materials offering excellent chemical resistance: PEEK, Kel-F®, PTFE (CV-3301 and CV-3302 only), stainless steel or gold-plated stainless steel springs, and perfluoroelastomer.
Our standard 1/4-28 Inline Check Valves accommodate 1/32"", 1/16"", 1/8"" and metric (1.0 - 3.0 mm) OD tubing, depending on the fittings used. Select from Upchurch Scientific's broad line of Flangeless, Super Flangeless and VacuTight fittings. All four valves have a 0.020"" thru-hole."
