3-piece stainless steel butterfly valves feature excellent acid and alkali resistance and high temperature resistance,with low 
permanent compression deformation.Equipped with precision-forged valve discs,these quick-installation valves can withstand 
pressure ≤1.0 MPa without deformation.
Their metallurgical structure is superior to precision castings.The valves are characterized by low operating torque and long 
service life,with normal opening and closing of more than 100,000 cycles.
This series of valves is available in various standard versions,including DIN,3A,SMS,ISO standards
