Nowadays,Ministry of Industry and Information Technology of the People’s Republic of China published the five new standards of valve industry.
October 29th,the Ministry of Industry and Information Technology of the People’s Republic of China published “No 63 Declaration of the Ministry of Industry and Information Technology of the People’s Republic of China in 2015”.According to the profile which was approved by the government.Among the profile,the manufacture standard are 648 proposals,the auto industry standard are 13 proposals, the construction material are 3 proposals. The standards related valve and the security pressure relief operation industry are 5 pieces.

 These five pieces of standard are:

 1.the first one is the JB/T 8527-2015 witch has replaced the JB/T 8527-1997, this has ordered the term、meaning 、type of construction、size and test package etc requirement. This kind of product was widely used on the nominal pressure from PN2.5-PN160 and Class 150、Class900，the butterfly which nominal diameter is DN50-DN600,the temperature range was from -29℃-538℃.
 2.The second one is the JB/T12386-2015 which has ordered the term、size、construction type、technology requirement、testing、logo and package. The exhaust valve which was widely used on the nominal diameter from DN15-DN25，the nominal pressure is less than PN25.
 3.The third one is the JB/T 12387-2015，which has ordered the construction type、material、transportation and package requirement. This kind of exhaust valve was widely used in the diameter from DN15-DN100(NPS1/2-NPS4),the pressure grade is less than PN760.
 4.The forth one is the JB/T12746-2015.
 5.The fifth one is the B/T12526-2015.
