Robertshaw RP-1072 Vacuum Regulator or Relief Valve

Since the RP-1072 Series regulators are restricted to vacuum applications, the range of pressures under control cannot vary beyond 0 psig and -14.7 psig. The values tabulated below in the column headed "Maximum Controlled Pressure" are applicable to the corresponding valve size and type tabulated when the adjusting spring is fully expanded. Similarly, "Minimum Controlled Pressures" apply to the valve size and type indicated when the adjusting spring is fully compressed. The actual adjustable range varies slightly from one valve size to another.
