Triple Eccentric Butterfly Valve is suitable for steam pipes of various pressures and temperatures as well as steam condensation pipes of different pressures because of its good high temperature resistance and zero leakage characteristics. It can be used in pipelines from process steam of petrochemical industry to medium and low pressure steam system of power plant, steam condensation water recovery system and urban heating and steam supply system.

Triple Eccentric Butterfly Valve are suitable for process pipelines in petrochemical industry, including various hydrocarbon media, pipelines with hard particle catalysts, etc. Taking FCC unit in refinery as an example, we have successfully applied three eccentric hard-sealed butterfly valves in the following occasions: main fan outlet pipeline and vent valve; air compressor population, outlet, flare vent valve; slurry pump outlet population; flue gas turbine population and bypass; medium and low pressure steam, etc. The coke cleaning valve at the cracking furnace outlet of ethylene plant is a kind of valve with harsh application conditions in petrochemical industry. Carbon particles contained in the medium may accumulate on the sealing surface of the valve. Before closing the valve, it is necessary to sweep the sealing surface of the valve by steam to remove the carbon particles that may accumulate on the sealing surface. 

Therefore, the coke cleaning valve here can be replaced by a Triple Eccentric Butterfly Valve with steam sweeping. Replace. Liquefied petroleum gas (LPG) is easy to leak, and the main valve of an import and export tank is more reliable by using a triple eccentric butterfly valve. High viscosity asphalt, fuel oil and materials such as sulphur that need to be transported in melting state can be used as triple eccentric butterfly valves with steam jackets. The Triple Eccentric Butterfly Valve with lining should be used in the high temperature flue gas pipeline of heating furnace. Gas separation and other chemical production processes require ultra-low temperature. Tri-eccentric butterfly valves with radiating fins can adapt to ultra-low temperature environment.

In chemical industry, it is sometimes required that the valve does not leak at all, so a butterfly valve with three eccentricities and double seals can be used to meet this requirement by using two cut-off valves, a short tube with check valve in the middle, or a fixed ball valve with check valve. PSA pressure swing adsorption hydrogen purification device requires valve to open and close frequently without any leakage. Tri-eccentric hard-sealed butterfly valve can be used as the preferred valve.
In metallurgical industry, it is difficult to control pipelines such as high temperature flue gas of reheating furnace in rolling process, oxygen and nitrogen blowing in converter of steel plant, emergency exhaust of blast furnace blower, etc. The main problem is that the air leakage of hot air valve is too large. For example, using tri-eccentric butterfly valve, the above problems are expected to be solved.
In alumina industry, tri-eccentric hard-sealed butterfly valves have been used for gallium recovery. In molten salt heating system, Triple Eccentric Butterfly Valve have better cut-off performance than ball butterfly valves. At present, Triple Eccentric Butterfly Valve can be used in all cases where gate valves or other valves have problems (such as molten salt system).
Above is the application of zero leakage Triple Eccentric Butterfly Valve arranged in small order. For your reference, if you need to purchase Triple Eccentric Butterfly Valve, please call.
