Hard seal Trip Eccentric Ansi Class150 WCB Butterfly Valve

• Hard seal butterfly valve is a kind of compoent used to realize the on off and flow control of pipeline system
• it has been widely used in many fields such as  petroleum,chemical industry,metallurgy,and hydropower,in and the sealing material is rubber ,ptfe,Due to structural limitaions,it is not suitable for high temperature,high pressure,corrosion and wear resistance industries.
• The exsiting one of the more advanced butterfly valve is a three eccentric metal hard seal butterfly valve
• The valve body and seat are connected components,and the seat sealing surface layer is surfacing with temperature-resistant and corrosion-resistant alloy materials
• The multi-layer soft stack seal is fixed on the valve plate
• Compared with the traditional butterfly valve,the type of butterfly valve has high temperature resistance,easy operation,no friction when opening and closing,and the seal is increased when the torque of the tranmission
