OUWEI TRIPLE ECCENTRIC ALL METAL HARD SEAL BUTTERFLY VALVE

◆Product Overview
The structure and technology of the butterfly valve is advanced in the field of the butterfly valve at home and abroad,valve in the early design through CAD
CDF design and analysis and constantly verify the optimization of three eccentric parameters,combined with modern CAM Processing technology to achieve
two-way valve pressure zero leakage,sealing pair using all metal hard and hard without auxiliary seals and which design,valve High temperature resistance,high
pressure resistance,corrosion resistance,erosion resistance and other high quality characteristics,according to different working conditions to change the
material configuration and add Technology,so that it can meet the use requirements in a variety of harsh working conditions

◆ Characteristics
1.Bidirectional pressure bearing:the design and development of the valve is carried out through the design and analysis of CAD and CDF and the continuous verification and optimization of tri-eccentric parameters. After repeated tests,it is carried out in combination with modern CAM processing technology High parts size machining accuracy,strict control of form and position tolerance means to achieve the valve bidirectional pressure zero leakage,the valve is not limited by the direction of installation;
2.the use of all metal hard sealing pair: the valve seat using integral forging,sealing surface welding si taili alloy or other alloy technology,its biggest characteristic is the sealing pair using all metal hard structure Design,and there shall be no more non-metallic materials such as PTFE ,graphite,rubber asbestos board interlining.fundamentally changed the seal structure,the valve with high temperature(850 C) or less,resistant to low temperature(196 ℃) High pressure resistance (2500Lb unidirectional pressure,up to 600Lb bidirectional pressure),corrosion resistance,erosion resistance,long life,good sealing performance and other characteristics,according to different working conditions and environment design to change the material configuration and Processing technology,so that it can meet the use requirements in various harsh working conditions

◆Use
The butterfly valve has the characteristics of high temperature resistance,high pressure resistance,corrosion resistance,erosion resistance and so on
It can be used safely in various harsh working conditions.It is widely used in power plant cooling water circulation system,urban water supply system thermal pipe network,petroleum,chemical and other related industries
