NRS Series

Company Name : Hale Hamilton

NRS and NR are ranges of spring-loaded, non-return or check valves. They are suitable for use with gases or liquids to prevent reverse flow in high-pressure lines. The NRS range is sealed by an elastomer O ring. The NR range is hard seated. The main closing force is provided by the process pressure. The spring ensures that the valve will close at any orientation. The internal design of the valve ensures that there is minimal restriction to flow.
