The SCV Series - an All-Inclusive Selection of Check Valves

In order to ensure safety, designers rely on air, gravity, and anti-siphon check valves to automatically control a fluid's directional flow - gas or liquid. This functionality helps to prevent backflow and ensure proper operation by end users. Industry-leading ease of use can be attributed to the ability of the check valves to operate in any spatial orientation as well as the ease of removing air bubbles during priming. The SCV valve's patented silicone membrane is closed in stand-by position and the seal mechanism avoids a retrograde flow even at the lowest back flow rates of 0.1 ml/h. This feature helps guarantee:

1. Protection of a line in case of back pressure caused by situations such as pinched tube or closed roller clamp.
2. Avoidance of cross-contamination from one part of line to another.
3. Prevention of unwanted free flow under gravity.
4. Air vent functionality for applications such as enteral feeding.

Available in ABS, SAN, and polycarbonate resins, the SCV Series check valves are DEHP and latex-free as well as in accordance with USP Class VI and ISO 10993 standards. The materials withstand EtO and gamma radiation, and on special order can even be autoclavable. The wide variety of end fitments include tubing pockets, sockets, and male and female luers that comply with ISO 594-1 and 594-2 standards. Sizes are made to fit with .118" (3.0mm), .122" (3.1mm), .161" (4.1mm), and .165" (4.2mm) tubing IDs. Cracking pressure ranges for one-way check valves are <= 12mBar (.174 psig) and for anti-siphon valves are 100-300mBar (1.450-4.351 psig).
