Product Overview
The plug rotates to connect or isolate the flow passage, and the selected lining forms part of the wetted arrangement. Polymer choice must be matched to the medium and complete valve operating conditions. Chinese-standard configuration does not establish an unlisted GB or HG standard number, a pressure rating or a universal flange pattern.
Selection and Ordering Notes
- Specify the required Chinese-standard design, flange and inspection references and editions.
- Choose PFA, PTFE or FEP after reviewing process and cleaning fluids and operating conditions.
- Confirm the actual body, plug, lining and stem-sealing specification.
- Provide connection dimensions, gearbox clearance and the required operating and shutoff duty.

Frequently Asked Questions
Can I choose between PFA, PTFE and FEP for this valve?
Yes. The three lining materials are confirmed selectable options. State the selected material on the order and obtain its complete valve rating and compatibility confirmation; they should not be treated as interchangeable.
Will this Chinese-standard valve fit my existing pipeline flanges?
Send the actual flange standard, nominal size, facing and installation dimensions. Request the quoted valve drawing; a country-standard description alone is not sufficient to establish fit.
How does this page differ from the American-standard PFA plug valve?
This page covers the Chinese-standard configuration with PFA, PTFE or FEP lining options. The separate American-standard page has PFA confirmed. Compare the quoted design and flange details as well as the lining, rather than choosing only by appearance.
