Products Description
Triple offset valves are widely used in industrial pipelines such as metallurgy, electric power, petrochemical industry, water supply and drainage, and municipal construction where the medium temperature is ≤425°C to regulate flow and load-break fluids.
The applicable scope of the triple-eccentric butterfly valve can withstand pressures up to 2500 pounds, temperatures as low as -196 ℃ and up to 700 ℃, sealing can reach 0 leakage, and control ratios as high as 100:1 or more. In other words, in various harsh and critical process control pipelines, whether it is an on-off valve or a control valve, as long as the type is properly selected, butterfly valves can now be used with confidence and at low cost.

Double Offset Butterfly Valve vs Triple Offset Butterfly Valve
The double offset valve is an improvement of the concentric/single offset valve and provides more versatility than the single offset. Feature comparisons are noted between the double and triple below:

|
Seal type and friction |
When compared to the single offset, the double offset greatly reduces friction. However, it still relies on plastic deformation for sealing. As a result, soft materials are still used for the valve seat. |
Maintains metal-to-metal seal with contact pressure. |
|
Fluid service |
Suitable for handling clean fluids only, due to friction in its sealing mechanism. |
Maintains effectiveness, even in dirty fluids. |
|
Applications |
Can serve in several industrial applications including water treatment, chemicals, oil and gas, and HVAC. |
Also serves in industrial applications, but suits scenarios with higher operational demand. |
|
Cost |
Comes at a moderate cost i.e. more expensive than single offset valves but less than triple offset valves. |
The specialized machining required to achieve superior sealing makes it more expensive. |
