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.
