The Application Trend of Triple Eccentric Butterfly Valves in High-Temperature and Critical Pipeline Systems
In the past two years, more and more customers have started to use triple eccentric butterfly valves instead of traditional butterfly valves or some gate valves and globe valves in oil and gas, LNG, energy power stations and marine pipeline projects. The main reason is that the triple eccentric structure can reduce the friction of the sealing surface, maintain stable sealing under high temperature, high pressure or corrosive medium conditions, and at the same time reduce the actuator torque and maintenance frequency.
Sichuan Yinling Machinery has been engaged in the manufacturing of valve components and complete valves for over 28 years. Our main products include valve bodies, valve stems, valve seats, valve balls, and complete ball valve and butterfly valve assemblies. For the three eccentric butterfly valve project, we can produce according to customer drawings and standard requirements. Common materials include WCB, LCB, LF2, F11, F22, CF8M, 316L and duplex stainless steel, etc., to meet the requirements of different temperature and pressure grades.
In the actual manufacturing process, the angle accuracy and surface roughness of the sealing surface have a significant impact on the performance of the valve. We control the key dimensions through CNC precision machining and final grinding, and combine PMI material inspection, UT/PT/MT non-destructive testing, and EN10204 3.1 material certificates to ensure the stable and reliable quality of the valve. For first-time cooperation customers, we support small batch trial orders and provide EXW or FOB shipping methods to facilitate customers to verify the product performance.
Applications: At present, the three eccentric butterfly valves and related accessories produced by Yiling Machinery have been applied in marine systems, steam pipelines, oil and gas transportation, and energy equipment projects. The reason why customers choose us is simple: timely communication, stable processing accuracy, controllable delivery time, and the ability to provide practical manufacturing suggestions based on drawings, helping customers reduce processing costs and later maintenance risks.
As global industrial pipelines develop towards higher temperatures, pressures and higher sealing grades, the demand for triple eccentric butterfly valves continues to grow. Sichuan Yiling Machinery will continue to improve its testing and processing capabilities to provide OEM customers with stable and reliable valve manufacturing support.
