Safety valve problems
Dear Sirs,
In reference with the phone call of today what Mr. Sinchai of Urmatt you will find enclosed
We hereby do send you 2 values which we have problem with.
One valve with label opened one time at the set safety value of 55 BarG. After this is starts opening at about 35 BarG and is leaking. We do not know the cause of it.
One value malfunction the other valve malfunctioned and was ripped of the tapwire. Reason unknown to us. The valve did fly around as a rocket
.
The Valves are provide by Sutee Group and are supplied to work in a system that works at 50 BarG with CO2 and N2 in a mix or pure. The system working pressure is 50 BarG the valve have been certified by your organization as we understood from Sutee Group.
Our Question are:
Can you tell me know what problems are?
- Why looking at 495 bar the system can not work at 50 Bar and the valves are leaking around 49 BbarG therefore not possible to get the desired working pressure of 50 BarG
-We do have to other values supplied for the same system of the same brand supplied by Sutee Group what can we expect of these valves.
