Hardware knowledge: six characteristics of hard-sealed butterfly valve products

The valve is a control component in the fluid conveying system, which has the functions of cut-off, regulation, diversion, prevention of reverse flow, stabilization, diversion or overflow and pressure relief. Valves used in fluid control systems, ranging from the simplest shut-off valves to extremely complex valves used in automatic control systems, have a wide variety and specifications. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media.

Product features of hard seal butterfly valve:

1. The hard-sealed butterfly valve adopts a triple eccentric sealing structure, the valve seat and the butterfly plate are almost wear-free, and have a tighter and tighter sealing function.

2. The sealing ring is made of stainless steel, which has the dual advantages of metal hard seal and elastic seal. It has excellent sealing performance, corrosion resistance, and long service life regardless of low temperature and high temperature.

3. The sealing surface of the butterfly plate adopts surfacing cobalt-based cemented carbide, the sealing surface is wear-resistant and has a long service life

4. The large-size butterfly plate adopts the quilted frame structure, which has high strength, large flow area and small flow resistance.

5. The hard-sealed butterfly valve has a two-way sealing function, which is not restricted by the flow direction of the medium during installation, and is not affected by the spatial position. It can be installed in any direction

6. The driving device can be installed in multiple positions (rotated by 90° or 180°), which is convenient for users to use.
