Boiler Safety and Water- Pressure Relief Valves

When more than one relief valve is provided on either hot-water heating or hot-water supply boilers, the additional valve (or valves) may be set within a range not to exceed 20% of the lowest pressure to which any valve is set. Each pressure-relief valve should reseat tightly with a blowdown of not more than 25% of the valve setting.
