Summary
HDH100 series second-generation double eccentric butterfly valve (also known as high-performance butterfly valve) adopts a unique eccentric structure for the valve plate and seat, which has the characteristics of compact structure, good sealing performance and long service life, with tight shut-off and regulation functions, widely used in tap water, sewage, oily liquids or air, gas, natural gas, steam and other media for chemical, power, textile, food, medicine, paper and other industrial applications, municipal engineering and waterworks etc.
Features
Unique seat design, Superior Performance
The unique snap ring of valve seat offer the live load, can effectively compensate the gap of medium temperature and pressure, and wear. No need to add O-rings or metal parts to keep the seal. At the same time, when the lip seal seat contacts with the disc, it can maintain a uniform and continuous sealing line to achieve long-term reliable sealing, the bi-directional leakage class is ANSI VI;
The valve seat is installed on the valve body through interference insert, and ex-works after the pressure sealing test approved, when the valve is installed on the pipeline , the pipeline installation force is beneficial to better valve body sealing and seat sealing, and the valve seat can be replaced without disassembling the buttergly valve disc and stem, which greatly reduces the maintenance.
