Excess Flow Check Valve

All LPG tank cars, LNG tank cars and Butane tank cars, transport trucks,

Hemco Excess Flow Check Valves provide instant shutoff in the event of a hose break or line failure, preventing the release of hazardous or inflammable products to the area which can result in a disastrous fire or explosion and untold damage to personnel and equipment. When a line fails, an excessive amount of product is released in a matter of seconds. Past experience has proved that in many instances the operator is unable to reach the shut-off, check valve due either to injury, or the whipping action of the hose. Take the guess-work out of this situation with automation.
