These check valves are designed to prevent backflow in flexible tubing systems used in vacuum applications. Featuring a simple, compact design, they operate in any position and provide reliable one-way flow control in low-pressure environments. Constructed with polyethylene bodies and diaphragm-style disks, these valves are ideal for air and gas applications where maintaining directional flow is critical.
