Notes:

Carbon steel valve body can be customized for DN65~150. At this time, the applicable temperature is Ib: -9~80℃,Va: -29~220℃.
ZCH-40Q and ZCH-50Q thread connections need to be customized, and generally production will not be carried out forsmall quantity.
G thread is the conventional thread, ZG (PT), NPT and other threads can be customized according to users´ requirements.
The flange is manufactured according to GB/T9124 standard by default, can also be manufactured according to the standards specified by users, such as JB/T79-1994, HG/T20592, ANSI, JIS, DIN and other standards.
