▶▷All parts are covered by fluorine material, which completely prevents corrosion of metal parts by corrosive media. ▶▷The valve seat filled with rubber has good elasticity, is easy to operate, has a long life, and has better sealing. ▶▷The centerline structure can be used for fast cutting off or adjusting the flow, suitable for occasions requiring reliable sealing and good adjustment characteristics. ▶▷The valve body of the fluorine-lined butterfly valve adopts a split type, which is very convenient when replacing the valve stem. The valve can be completed without removing the pipeline. ▶▷Fluorine-lined butterfly valves are widely used in the transportation of liquids and gases (including steam) in various types of industrial pipelines, especially in the use of heavy corrosive media.

▶▷The metal hard seal 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. ▶▷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. ▶▷The sealing surface of the butterfly plate adopts surfacing cobalt-based hard alloy, the sealing surface is wear-resistant and has a long service life. ▶▷The large-size butterfly board adopts the quilted frame structure, which has high strength, large flow area and small flow resistance.

▶▷ The metal hard seal butterfly valve has a two-way sealing function. It 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. ▶▷Small opening torque, flexible and convenient, labor-saving and energy-saving. ▶▷High pressure resistance, corrosion resistance, wear resistance, long service life. ▶▷The driving device can be installed in multiple positions (rotated by 90° or 180°), which is convenient for users to use.

▶This valve adopts a double eccentric structure, which has a tighter sealing function as it closes, and its sealing performance is reliable. ▶The sealing material is matched with stainless steel and NBR oil-resistant rubber, which has a long service life. ▶The rubber sealing ring can be located on the valve body or on the butterfly plate, which can be applied to different characteristics of media for users to choose. ▶The overall baking varnish can effectively prevent corrosion and can be used in different media as long as the sealing material of the sealing valve seat is replaced.

▶Reasonable design, compact structure, easy assembly and disassembly, and easy maintenance. ▶Adopt rubber lining structure to reduce the friction of sealing ring and prolong the service life of valve. ▶The valve plate adopts T-shaped structure, and the sealing surface is linearly sealed. ▶Completely sealed, zero leakage. ▶Replace the valve plate sealing ring, O-ring, butterfly plate, rotating shaft and other materials, which can be applied to a variety of media and different temperatures.

▶This valve adopts triple eccentric sealing structure, the valve seat and butterfly plate wear little. ▶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. ▶The sealing surface of the butterfly plate adopts surfacing welding cobalt-based hard alloy, which is wear-resistant and has a long service life. ▶The large-diameter butterfly plate adopts the quilted frame structure, which has high strength, large flow area and small flow resistance. ▶The electric three-eccentric butterfly valve has a two-way sealing function. It 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. ▶The driving device can be installed in multiple positions (rotated by 90° or 180°), which is convenient for users to use.

▶The flow characteristics tend to be straight, and the regulation performance is good. ▶The driving mode can be manual, electric or pneumatic. ▶The seal can be replaced, and the seal is reliable to achieve two-way sealing. ▶Small and light, easy to disassemble and repair, and can be installed in any position. ▶The structure is simple and compact, the operating torque is small, and the 90° turn to open quickly. ▶The butterfly plate can be sprayed with a coating layer, such as nylon or PTFE, according to user requirements.

▶The unique design of three-way eccentricity enables frictionless transmission between the sealing surfaces and prolongs the service life of the valve. ▶Elastic seal is produced by torque. ▶The clever wedge-shaped design makes the valve have an automatic sealing function that is tighter and tighter, and the sealing surface has compensation and zero leakage. ▶Small size, light weight, light operation, easy installation and reliable connection. ▶Pneumatic and electric devices can be configured according to user requirements to meet the needs of remote control and program control.
