What is a Check Valve?
Components that Control Flow
A check valve is a component that regulates the directional flow of fluids and comes in diverse configurations tailored to specific needs. Single-configuration check valves prevent backflow in one direction, requiring a positive pressure differential for fluid passage. They feature terminations such as luers, bond sockets, bond posts, and barbed designs. Our check valves are engineered with a range of opening pressure ratings, from low pressure options to high pressure variants, like anti-siphon valves, that resist gravity-induced flow. Made with USP Class VI compliant materials, our medical-grade check valves prioritize safety and compatibility with the human body. They minimize contamination risks while facilitating seamless priming and accommodating higher flow rates. Ideal for infusion, drainage, and irrigation applications, our check valves are essential for medical device designers seeking reliability and performance.
Material Information
We offer our customers direct technical information from resin manufacturers regarding the resins we utilize. This includes material data such as regulatory compliance, MSDS, typical properties, sterilization stability, and chemical resistance. We encourage testing our products in your specific application to ensure they meet your requirements effectively.

This reliable performance makes them ideal for disposable medical systems and other applications where consistent, one-way fluid transfer is essential. Disc check valves feature a polycarbonate housing and a silicone disc seal.
Dome Check Valves
Reliable Backflow Protection
Dome check valves are normally closed, one-way valves designed to prevent backflow in a wide range of IV and fluid delivery applications. Their compact design and reliable performance make them well suited for disposable medical systems that require consistent directional flow control. Featuring a low opening pressure of 0.43 psi (0.03 bar) and backpressure resistance greater than 45 psi (3.1 bar), they help ensure safe, efficient fluid management while providing dependable protection against reverse flow. Dome check valves are constructed with a polycarbonate housing and a silicone dome seal.
Luer Lock Check Valves
Secure Fluid Access
Luer lock check valves provide reliable needle-free access and one-way fluid control for a wide range of disposable medical applications. Designed for compatibility with standard luer syringes and connectors, they create secure closed-system access points that help reduce contamination risks while supporting safe, efficient fluid delivery. Available in multiple body profiles and connection configurations, including female and male luer lock connections, these valves offer dependable performance in IV therapy, catheter systems, and other fluid management applications. Features such as integrated luer lock ears for positive securement, compact footprints, and secure syringe engagement help maintain system integrity while supporting consistent, directional flow. Constructed from a range of medical-grade materials, including polycarbonate and PVC, luer lock check valves provide an economical and versatile solution for disposable medical devices requiring dependable fluid control and closed-system access.
Luer-Activated Check Valves
Needle-Free Fluid Access
Luer-activated check valves provide secure, needle-free access and reliable fluid control for a wide range of disposable medical applications. Activated by standard luer syringes and connectors, they help maintain closed-system integrity while supporting flushing, fluid delivery, catheter procedures, balloon inflation and deflation, and other fluid management processes. These valves deliver dependable performance for filling, holding, and releasing controlled amounts of fluid or gas while maintaining reliable flow control. Available in multiple body styles, profiles, attachment configurations, material options, and color-coded designs, they offer flexibility for a variety of device and clinical requirements. Features such as low-profile designs for space-constrained applications, high-flow performance for rapid inflation and deflation, and streamlined assembly options for catheter tubing systems make them well suited for single-use medical devices. Available in medical-grade materials including polycarbonate, PVC, polypropylene, and ABS, luer-activated check valves provide an economical, versatile, and reliable solution for disposable healthcare applications.
Syringe Valves
Reliable Fluid Transfer
Syringe valves are designed for use in syringe-based fluid delivery applications where dependable flow control and tubing connectivity are required.
