Introduction Of High Performance Butterfly Valve

High performance butterfly valve is also called double eccentric butterfly valve. It is mainly used for drainage of water plant, power plant, steel smelting, chemical industry, water source spring project, environmental facilities construction and other systems, especially for waterway and pipeline, as regulation and closure equipment. Compared with midline butterfly valve, high performance butterfly valve is more resistant to high pressure, longer service life and better stability.

Difference Between High Performance Butterfly Valve And Center Line Butterfly Valve

1. Eccentric design is different, ordinary butterfly valve is single eccentric, also known as the center line butterfly valve, generally used in water treatment, temperature and pressure are not big, rarely start open and close function, so only the center line symmetrical design can be. The high-performance butterfly valve is based on the axis and butterfly plate and cross-section of the different, and the design of double eccentric and triple eccentric high-performance butterfly valve, to reduce friction, increase service life and sealing degree.

2. The materials are different. Ordinary butterfly valves are generally made of cast iron and EPDM made of ordinary rubber, while high-performance butterfly valves need high temperature, high pressure and corrosive working environment, and are made of stainless steel and carbon steel

Special Design Of High Performance Butterfly Valve

The service life of the butterfly valve is longer than that of the middle line butterfly valve in geometric order; The torque is light, which can be reduced by 30% compared with the central line butterfly valve; The pressure range of application is wide, the working pressure can be up to 10MPa, which can be applied to all kinds of media. High performance butterfly valve is a new butterfly valve designed on the basis of absorbing the advantages of several butterfly valves with different structures. The sealing surface of the valve plate of the butterfly valve is a spherical arc body, and the sealing mechanism achieves a real dynamic sealing through the system pressure, so it has excellent cutting performance and durability. It has the advantages of small volume, light weight, wide manufacturing range and easy maintenance.
