the national valve Standardization Technical Committee organized a delegation to participate in the meeting. The head of the delegation was Secretary General Huang Mingya. The iso/tc153 registered expert of the international valve Standardization Technical Committee and the chairman of Huangshan liangye Valve Co., Ltd. Xiang Meigen attended the meeting

from September 9 to 11, 2015, the International Technical Committee for standardization iso/tc 153 (valves) held its second plenary session in Paris, France. Its three working groups WG1 (driving device and its connecting accessories), wg6 (ball valve) and wg7 (valves for chemical process and related industries) held meetings at the same time. More than 30 representatives from 11 countries including China, Germany, the United States, Japan, South Korea, Italy, the United Kingdom, France, Canada, Spain and Switzerland attended the meeting

the national valve Standardization Technical Committee organized a delegation to participate in the meeting. The head of the delegation was Secretary General Huang Mingya.

the main contents of this meeting are:

first, the stripping fixture of "ISO 5210 industrial valves - connecting accessories for multi turn valve actuators" and the standard of "ISO 5211 industrial valves - connecting accessories for partial turn valve actuators" are discussed

the second is to discuss the standard of iso/dis 7121 flanged steel ball valves for industrial use

thirdly, the newly formulated international standard iso/np19240 industrial valves - partially rotary lined valves for chemical processes and related industries was discussed

in June 2015, China took the lead in formally submitting a proposal document to the iso/tc153 Secretariat on the development of a new international standard for general requirements for electric actuators for industrial valves. In August 2015, South Korea also submitted an application to the Secretariat for the development of new international standards for valve electric devices. At the WG1 working group and plenary meeting, the Chinese delegation introduced in detail the background, process and scope of the proposal of the new international standard for reciprocal modulus called flexibility. After discussion and questioning, according to the proposal of the Chinese delegation, an agreement was reached at the iso/tc153 plenary meeting. The standard scope of the general requirements for electric actuators of industrial valves prepared by WG1 working group will include the general requirements for electric actuators of on-off and control valves, mainly including the requirements for design, test, marking and documentation of the piston of the oil cylinder. In short, China will take the lead in drafting this standard
