RS Series
Company Name : Hale Hamilton
Description
The RS series is a range of differential relief valves
suitable for general industrial (compressed air) or for
Oxygen applications.
The valve is operated by an internal piston that is larger
than the flow area. The process pressure acts on the
difference in these areas (hence “differential”). This
means that the spring can be small for high pressures.
Each valve is adjustable within a range of pressures.
The range depends on the size of the piston and the
strength of the spring.
RS valves are available with either direct or banjo bolt
mounting.
