Improper use may cause cavitation, which may cause the rubber seat to peel off or be damaged. Sanitary Butterfly Valve Methods to solve the cavitation problem:

The butterfly plate sealing ring of the three-eccentric multi-layer metal hard seal butterfly valve is a soft and hard laminated metal sheet, which has the dual advantages of metal sealing and elastic sealing, and has excellent sealing performance regardless of low or high temperature conditions.

The three-dimensional eccentric structure is adopted, and there is almost no friction between the valve seat and the butterfly plate, and the internal parts of the valve are almost not damaged when closed; this structure greatly improves the performance of the valve in use, and has a sealing function that becomes tighter and tighter as it is closed.

Bushings are installed on the upper and lower parts of the valve stem, and the wear and friction resistance generated by each bushing is very small. This structure can prevent wear and adhesion, and also improve the service life.

The sealing surface of the valve body is made of surfacing alloy steel or Stellite hard alloy, and the sealing surface of the stainless steel hard seal sanitary butterfly valve is resistant to wear, erosion and corrosion; it has a long service life.

The hard-sealed sanitary butterfly valve has a unique structure, small switching torque, flexible operation, labor-saving, convenient, and is not affected by the high or low pressure of the medium. It has reliable sealing performance and can be used as an opening, closing and regulating device.
