Fly Ash Valve

FREE-VALVE’sfly ash valveis mainly used in feeding and dumping the dry powder , which not only adopt toughening ceramic as shut off and wear out resistance material, but also design construction of pressure self-sealing and valve disc auto-rotate, so as to the sealing surface within the dry powder get more wear resistance in process of opening and closing frequently.Thereby,it guarantee the high requirements oftightsealing performance of this valve and long working time.

Features:

1. Sealing pair is made ofengineeringceramics，which has perfect performance to resist wear anderosion.

2.Bi-directional 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 dustjammingin the process of the opening and closing of valve.

4. The valve disc rotatingl motion can avoid the ash deposition on the sealing surface during opening and closing, so the valves have longer service time.

5. The blow sweep port can be set on the valve body according to different operating conditions.
