Stainless steel pneumatic ceramic lined double disc gate valve
Stainless Steel Pneumatic Ceramic Double Disc Gate Valve is mainly installed in feeding and dumping the fly ash at coal power plant .
Features:
1. Sealing pair is made of structural ceramics，which have perfect performance to resist wear and flushing.
2. Two-side sealing can realized due to double disc structure of the pneumatic ceramic double disc gate valve.
3. It inserts spring between double valve discs to ensure self- sealing through bi-directional flexible preload pressure of spring, having characteristics of low pressure bi-directional sealing and without dust clogging phenomenon in the process of the opening and closing of valve.
4. The valve disc rotational motion can avoid the ash deposition on the sealing surface during opening and closing, so the valves have much longer service.
5. The blow sweep port or automatic blow sweep device can be set on the valve body according to different operating conditions.
6.Stainless steel material makes the valve working in corrosive medium ,such as the coal power plant in sea side .
