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. Double-configuration check valves manage bidirectional flow by directing fluid to multiple outlets sequentially. 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.
Single-Configuration Check Valves
Plastic Valves to Prevent Contamination
Our single-configuration check valves offer a versatile range of anti-siphon and barbed configurations crafted from a variety of high-quality materials. We also offer gravity set check valves as part of this range. Our single check valves are available with terminations such as male and female locking luers, bond sockets, and bond posts in various sizes and combinations. Designed to minimize contamination risks, these valves boast precise, low opening pressures and superior flow rates, making them indispensable for medical device designers. Each valve includes DEHP- and latex-free silicone diaphragms, ensuring low priming volume and ease of air bubble removal during operation in any orientation.
Single-Configuration Valves for Accurate Flow Control
Nordson MEDICAL's anti-siphon check valves excel in controlling directional flow and preventing backflow, featuring higher opening pressures that effectively safeguard against inadvertent fluid flow, particularly when connecting to higher-flow lines. Crafted from medical-grade materials, these valves are meticulously engineered to operate flawlessly in any orientation, offering improved air vent functionality crucial for healthcare applications like enteral feeding. Meeting rigorous USP Class VI and ISO 10993 standards, our anti-siphon check valves are trusted worldwide by healthcare professionals for their superior quality and reliability.
Single-Configuration Valves with High Flow Rates
Our high-flow check valves are specifically designed using premium medical-grade materials certified to meet USP Class VI and ISO 10993 standards, ensuring optimal performance for flushing and irrigating body cavities. Engineered to maximize flow efficiency with a less restrictive path, these valves offer enhanced responsiveness and facilitate efficient removal of air bubbles during priming.
Single-Configuration Valves for IV Gravity Sets
We offer check valves specifically designed for gravity sets, crafted from medical-grade materials and engineered to effectively prevent backflow in their closed-valve state. These unidirectional valves stand out with the lowest cracking pressure available, ensuring reliable operation in any spatial orientation. Enhanced with improved air vent functionality for critical applications like IV administration, our gravity set check valves are indispensable in medical settings where eliminating backflow is paramount.
Single-Configuration Valves with Secure Connections

Designed to minimize contamination risks, these valves boast precise, low cracking pressures and higher flow rates, making them ideal for medical device designers focused on infusion, drainage, and irrigation applications.
Double-Configuration Check Valves
Plastic Valves to Maintain Fluid Purity
Nordson MEDICAL's unique bi-directional double check valves, are expertly designed to transfer clean fluid from a supply vessel to a use site without contamination. The fluid supply vessel connects to the valve supply port (chimney) via a luer connection or tubing. Fluid is withdrawn from the supply vessel by a syringe or another device attached to the aspiration port. When the syringe is compressed, the fluid is transferred through the exit port to the use site, maintaining its purity. These double check valves are crafted from medical-grade polycarbonate resin with a silicone diaphragm. Featuring two inlet ports, these check valves seamlessly connect to female luer aspiration and male luer discharge ports. Our valves ensure reliable, contamination-free fluid transfer without disconnecting the syringe, making them an ideal choice for medical applications.
