Note! Check domestic regulations - Safety Valve Standards
Safety valves should be removed at least once each year for inspection and cleaning of any deposits that might affect their operation.
To eliminate the necessity of shutting the system down for the inspection, a three-way stop valve may be installed under 2 safety valves, each with the required relieving capacity, installed so that both safety valves cannot be closed off from the vaporizer at the same time. Alternatively may 2 or more separate safety valves be installed with individual shutoff valves, in which case the shutoff valve stems is mechanically interconnected in a manner that allow full required flow capacity at all times.
