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. Available in medical grade materials and multiple barb sizes the valves feature more precise, lower crack pressures, higher flow rates, low priming volume, air bubble mitigation during priming and operate in any spatial orientation.
The check 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. All check valves feature DEHP- and latex-free silicone diaphragms and all materials of construction satisfy USP Class VI and ISO 10993 criteria.
According to Ken Davis, Global Product Line Manager, “We are very pleased to have a barbed check valve option for our customers. We have been providing barbed luer and tube-to-tube products for over 45 years to the market. Our customers like this type of termination and it only makes sense for us to provide the same kind of value and differentiation in a barbed check valve.”
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:
Available in MABS, 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 barbs, tubing pockets, sockets, and male and female luers that comply with ISO 594-1 and 594-2 standards. Sizes are made to fit with 3/32" (2.4 mm), .118" (3.0mm), .122" (3.1mm), 1/8" (3.2 mm), .161" (4.1mm), and .165" (4.2mm) tubing IDs. Cracking pressure ranges for barbed check valves are ≤ 6mBar, for one-way check valves are ≤ 12mBar (.174 psig) and for anti-siphon valves are 100-300mBar (1.450-4.351 psig).
The latest plastic diaphragm check valves improve flexibility, flow control and safety in medical device applications.
