American Standard Gate Valve Standard Code, Standard Specification And American Standard Gate Valve Standard Classification

American standard gate valve standard code, standard specification and American standard gate valve standard classification: API600, API6D, API603, API602, among which American standard API603 is often made of stainless steel, and its sealing valve seat is the body (the upper seal is the body); API602 is a forged series standard gate valve with conventional standard pressure: 150LB, 300LB, 600LB, 900LB, 1500LB, 2500LB, 800LB, etc., and the materials are: A105, F304, F316, F321, F11, F5

American standard gate valve refers to the design that meets the American standard production standard. The common standard codes of American standard gate valves are: ASTM (American Society for Testing and Materials Standard), NSS (American Valve Association Standard), API (American Petroleum Institute Standard), ANSI (American Standard). Each country has its own production standards for valves. Next, I will introduce the various codes of valve standards:
ISO-national standard
CV-valve association standard
EJ-nuclear industry ministry standard
YB-metallurgical ministry standard
HG HGJ-chemical ministry standard
Q/TH-machinery department chemical general machinery special standard
DF-high pressure helium fertilizer valve design standard
GB-national standard
SY-petroleum ministry standard
DL-energy ministry machinery
BS-British national standard
JIS-Japanese industrial standard
DIN-German standard
NF-French standard
