Check Valves High Capacity Excess Flow
Protect high pressure transfer lines against ruptures or failures
Flo-Gard provides 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, a terrific 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 valve due either to injury, or the whipping action of the hose.
Operation - Automatic
Flo-Gard Excess Flow Check Valves are specifically designed to permit high flow, but to close instantly and automatically when the flow becomes excessive due to line failure or other reasons. Liquid can flow through the valve in either direction, however, the flow will be shut off in the direction indicated on the drawing in the event the volume through the valve exceeds the predetermined amount.
Construction - Rugged
The Flo-Gard valve body is of all welded steel construction consisting of forged steel flanges and seamless cold drawn tubing, seal welded and hydrostatically tested at 500 PSI. Internal parts are of special steels and stainless steels to insure trouble free operation for a long period of time.
Installation - Simple
Flo-Gard may be installed in any size line up to 4", horizontally, or vertically, with flow in either direction.
