Note:1.The sealing test pressure for the butterfly valves above,ranging from DN32 to DN800,is 1.0Mpa;DN900~DN1000 is 0.6Mpa;DN1200~DN2000 is 0.25Mpa;
If the working pressure exceeds 1.0Mpa,it is recommended to use a three eccentric butterfly valve;
3.The connection dimensions of the above butterfly valves are manufactured according to the 1.0Mpa standard.If there are special requirements such as valve plate lining rubber,they should be specified when ordering.
