Triple eccentric butterfly valves are designed for severe service conditions where tight shut-off, high temperature resistance, and long service life are critical. Thanks to their unique triple-offset design, these valves eliminate seat rubbing, reduce wear, and achieve reliable metal-to-metal sealing, even under extreme pressure and thermal cycling.
Power Generation Systems
Triple eccentric butterfly valves are widely used in:Steam lines.Boiler feedwater systems.Condensate and cooling water circuits
Their ability to handle high temperatures and high pressures makes them ideal for power plants, where frequent thermal expansion and contraction would quickly damage conventional valves.
Oil and Gas Industry
-
①Crude oil and refined product pipelines
-
②Gas transmission and distribution systems
-
③Compressor and pumping stations
The fire-safe design and tight shut-off performance help meet strict safety and environmental requirements in oil and gas facilities.
Petrochemical and Chemical Processing
-
①High-temperature chemical fluids
-
②Corrosive or abrasive media
-
③Process isolation and flow control
With metal sealing surfaces and advanced coatings, they maintain sealing performance where soft-seated valves would fail.
Marine and Offshore Applications
-
①Main seawater cooling systems
-
②Ballast and bilge systems
-
③Fuel oil and lube oil pipelines
-
④Offshore platforms and FPSOs
Their compact structure and long service life reduce maintenance needs onboard ships and offshore installations.
District Heating and Cooling Networks
-
①Reliable shut-off at elevated temperatures
-
②Low operating torque
-
③Long-term sealing stability
They are often installed in district heating plants, energy transfer stations, and thermal networks.
Metallurgy and Heavy Industry
-
①Steel mills
-
②Coke oven gas systems
-
③High-temperature air and gas pipelines
Their robust construction withstands vibration, dust, and thermal stress.
Flue Gas and Emission Control Systems
-
①Flue gas desulfurization (FGD) systems
-
②Exhaust gas isolation lines
-
③Waste heat recovery systems
The metal-to-metal sealing design ensures performance even with particulate-laden or hot gases.
Why Triple Eccentric Butterfly Valves Fit These Applications
-
①Bubble-tight shut-off (often ANSI Class VI)
-
②Excellent performance at high temperature and pressure
-
③Reduced wear due to non-rubbing sealing action
-
④Compact size compared with gate or globe valves
