“Safety relief valve SVN is primary designed for instalation on propane, butane and LPG storage vessels, although it can be equally efficient installed on all other gas instalations”

High discharge flow makes this valve ideal for a quick overpressure relief caused by temperature increase

“Safety relief valve SVN is verticaly straight exhaust type of valve, with thread end connection for exhaust pipeline. It automatically opens and relief limited volume of gas, and automatically closes when pressure normalizes in the system it

secures.”

 

“Safety valve SVN acts directly according to the developed force, as a result of gas pressure on the plate the set force of the spring is resised. With the adequate increase of pressure, the seat is lifted up to max. 1/4 seat diameter and with this the

exiting conduit is opened.”
