LPG
Internal valves are installed in LPG tanks as a safety measure to prevent spillage if piping is damaged or tanks are tipped over. They are commonly installed in conjunction with compressors and/or pumps in stationary storage tanks, bobtail delivery truck loading and unloading lines or in-line installations.
The excess flow functionality of the internal valve shuts off flow automatically if there are large changes in pressure. The ball valve feature allows for manual shut-off by a lever whereas remote control is possible using other actuators. The internal installation increases safety dramatically by avoiding the shearing of the valve in terms of mechanical impact.
