SCV Series Check Valves

SCV Series check valves control directional flow to help prevent backflow. Products are available in several configurations, materials, and end fitments. The valves feature low priming volume, ease of removing air bubbles during priming and operate in any spatial orientation. All products feature DEHP- and latex-free silicone diaphragms and all materials of construction satisfy USP Class VI and ISO 10993 criteria. SCV Series products are offered in three different materials, MABS, SAN and polycarbonate, all featuring a patented silicone diaphragm. Several different end fitments are available, including tubing pockets, tubing sockets and male and female luer fitting ends.

DCV Series Double Check Valves

Nordson MEDICAL’s unique DCV Series bi-directional double check valve is designed to transfer clean fluid from a supply vessel to a use site. The fluid supply vessel is connected to the valve supply port (chimney) using a luer connection or tubing. The fluid is withdrawn from the supply vessel by a syringe or other device connected to the aspiration port. When the syringe is compressed the fluid is then transferred, through the exit port, to the use site without adulterating the fluid. DCV Series bi-directional valves are produced in polycarbonate resin using a silicone diaphragm, with two available inlet ports connecting to the female luer aspiration and male luer discharge ports.

SCV Series Barbed Check Valves

SCV Series barbed check valves were developed to provide a reliable mechanical connection and simplify tubing assemblies that often require multiple parts needed for in-line check valves. The valves feature 3/32” (2.4 mm) and 1/8” (3.2 mm) single barb ends in barb to barb straight through, reducing, and barb to male/female luer configurations. Barbed check valves reduce the risk of contamination and feature more precise, lower crack pressures and higher flow rates. They are ideal for medical device designers focused on bioprocessing, infusion, drainage and irrigation applications.
