Feelers Editorial Review

These check valves are made of PVDF and silicone rubber diaphragm material, with barbed retracting locks, making it easy to connect and disconnect. They have an opening pressure of 0.015mpa and below, and reverse pressure of 1.0mpa and below. While they are advertised as suitable for potable water and automobile vacuum switch control lines, some customers have had issues with these valves depending on the pressure and application. Some buyers have faced backflow issues, while others have experienced the valve splitting in half or not working as expected.

Pros

Made of durable materials
Easy to connect and disconnect
Works as expected for some buyers

Cons

InConsistent performance depending on the pressure and application
Not suitable for stiffer tubing
Some customers have experienced backflow or valve splitting.
