N Series

Company Name : Hale Hamilton


The N series is a range of, non-rising stem, balanced stop valves. They are suitable for use with gases or liquids where tight shut-off is required in highpressure lines. The pressure balanced spindle prevents the process pressure from loading the operating thread. This means that handwheel torque is low even at the maximum operating pressure of the valve. Mounting brackets are available. A pneumatically actuated variant of N6 is available.
