Description

All Kingston Relief Valves are manufactured under a quality control system accepted by the National Board of Boiler and Pressure Vessel Inspectors. Code valves are capacity certified by the National Board, manufactured in accordance with ASME Code, set and sealed at the factory.

Set pressure can deviate from the marked by ± 2 psig at or below 70 psig set pressures and ± 3% psig above 70 psig. Factory standard seat tightness for soft seat valves: no audible leakage at 10% below nameplate set. It is normal for spring-operated relief valves to exhibit leakage or simmer/warn, as the system operating pressure approaches the set pressure. For soft seat valves, this typically occurs at pressures at or above 90% of nameplate set pressure.

At very low set pressures (20 psi and below), the ratio of the downward spring force as compared to the upward pressure force is very small. In these cases it may be impossible to achieve seat tightness. Soft seat valves will typically provide a higher degree of seat tightness than metal, hard seats. Factory standard seat tightness does not ensure bubbletight seal regardless of material.
