Our excess flow earthquake relief valves are activated by three different methods: flow, seismic, and combined flow and seismic. When flow shutdown is required due to sudden flow events, these valves are used in terminals, gas and liquid lines, processing facilities, sub-terrain, and other applications. All custom products are designed to specific installation requirements, made in the USA, and are UL and ISO certified. Valves are tested in one of our three flow loops before being shipped domestically and/or internationally. Please view our catalog for more information.
Total Valve Systems understands the need for Low “E” fugitive emission control. Therefore, we have teamed up with industry-leading Chesterton to provide our customers with high-quality Low "E" packing. Our authorized installation center has an extensive program that meets the requirements for relief, control, and isolation valves. With these packing and installation methods our valves will have a five-year warranty. All products meet the latest LDAR requirements and are tracked through our "Total Valve Live" system.
Our lab is staffed by engineers to assist customers with performance testing and is utilized to help manufacturers of control, pressure relief, emergency shutdown valves, and regulators to achieve desired valve performance.
