For safety i usually use a sensor on my boilers or autoclaves. Set a sensor + set a condition on the them (no more than 4000 units steams for example) + use to redstone wire to turn of\turn off cover. If pressure will more of settled units - system will automatic turn off . P.S i haven’t a game under my hand now. I remember it was "giibble-o-meter sensor " or “Pressure sensor”
