Repeated order of ceramic double disc gate valves for coal fired CFB boiler from Pakistan
16, May, 2020

Our customer in Pakistan placed repeated orders of ceramic double disc gate valves to solve the abrasion problem in fly ash transportation system for coal fired CFB boiler.

The detailed working conditions for ceramic double disc gate valves are as follows:


1. Medium: Abrasive dry fly ash
2. Maximum ash temperature: 250℃
3 Ash pressure: 1MPA Nominal
4. Pneumatic actuator air supply pressure;0.4-0.6MPA
5. Ambinet temperature: 5-55℃
6. Connection: Flanged
7. Location: Outdoor
8. Climate: mostly dry & hot


To solve the abrasion problems, the body of ceramic dual disc gate valves are lined with ceramic which has excellent wear resistance, and the disc is also with ceramic sealing ring to be abrasion resistant.


Normally ceramic double disc gate valves are pneumatic operated, because they are used as discharge valves or feeding valves widely in pneumatic conveying system for fly ash, limestone, powder and other bulk materials etc.

With cermaic lining, the service life of ceramic dual disc gate valves have been increased dramatically.
With good quality and excellent service, we have won repeated orders from our customers.
