                Notes: 1. The sealing test pressure DN32~DN800 is 1.0 Mpa, DN900~DN1000 is 0.6 Mpa, DN1200~DN2000 is 0.25 Mpa.


                2. if the working pressure exceeds 1.0Mpa, the three eccentric butterfly valve is recommended.


                3. The connection sizes of the above butterfly valves are all manufactured according to 1.0 Mpa standard, such as valve plate rubber lining and other special needs, should be noted when ordering.
