Qosina offers an extensive line of Check Valves available in a variety of styles, in stock and ready for immediate delivery. High-Flow valves feature low flow resistance, low opening pressure, and positive seal against backflow. In-line valves feature low cracking pressure, which determines when the component starts to open; if back pressure is a concern, choose from Qosina’s variety of duckbill valves. Luer Activated are equipped with a needle-free design featuring a closed silicone plug that blocks flow until mechanically opened with a male luer connector. Dual Check Valves enable injection and aspiration from separate ports of a single connector. Qosina offers a variety of flow rates, materials, cracking pressure and back pressure options. Check Valve sample kits are also available which are ideal for testing.
