CANADA’S LEADER IN ENERGY PRODUCTS EQUIPMENT PLANT, TRUCK & TANK EQUIPMENT BACK CHECK VALVES & SIGHT FLOW INDICATORS Back Check Valves Allows flow in only one direction and are normally closed. Installed in liquid filling connections on stationary storage tanks, bobtail delivery trucks, and liquid transfer lines. The valves are frequently used in conjunction with globe, angle and ball valves, as well as large single-check filler valves. Fisher G200 Series Back Check Valves - Specifically intended for heavy-duty in-line service at the bulk plant’s transfer area. Soft seat construction gives tight shutoff for maintenance, while body design reduces flow resistance improving flow capacity. The G201 has a built-in flow indicator, which can be used to replace sight flow indicators.
