Disengagement box

FEATURES

Safety equipment for gas storage tanks. Disengagement box is designed to mount two or more safety relief valves allowing to remove one valve at a time for calibration and maintenance keeping the tank in operation. In this temporary condition the tank is protected against overpressure through the spare valve in service on the box.
The lateral pin, protected by a steel cover, moves a shutter through the internal channels driving the gas flow toward the selected valve.
The finishing is in galvanised steel.
