APPLICATION
Safety relief valve SVM-N is used downstream of pressure regulator to relief limited volumes of gas, and to avoid
triggering safety shut-off valves.
It’s ideal for low pressure settings due to high sensitivity provided by large diaphragm area.
DESIGN FEATURES
Safety relief valve SVM-N automatically opens and relief limited volume of gas, and automatically closes when
pressure normalizes in the system it secures.
Safety valve acts directly according to the developed force, as a result of gas pressure on the diaphragm the set
force of the spring is resised. With the adequate increase of pressure, the diaphragm is lowered and with this the
plate and therefore the exiting conduit is opened.
