Please note: only safety valves that have been set and sealed (corrected) by our company can be delivered with component symbol, and the set pressure must be BAR.
To test their proper function, simply turn the knurled (thumb) screw to the right to contact the relief valve pressure. Unscrew the entire upper part to remove impurities from the bearing indication and conical seal ring -- without changing the pressure setting. It can only be repaired by the manufacturer
definition
Set pressure = start leakage pressure can hear the start of leakage
Open the pressure valve fully open and release the gas
Closing pressure valve is closed and sealed (tight)
Opening pressure difference The difference between start-leak pressure and opening pressure
Closing pressure difference The difference between start-leak pressure and closing pressure
example
Set pressure 12,0 bar
Opening pressure (+10%) 13,2 bar
Closing pressure (-10%) 10,8 bar. Protection, etc. - IP 54 (EN 60529).
