OMC valves are not designed to cope with external stresses that can be induced by the systems in which they are inserted. It is the installer's responsibility to take these efforts into account and to take appropriate precau ons. -
Page 4: Tools And Consumables
Periodically check for any internal and/or external corrosion and/or erosion phenomena as they can cause significant damage to the parts under pressure, locally reducing their thickness and consequently their degree of safety.
