Pneumatic Ceramic Double Disc Gate Valve

PneumaticCeramic Double Disc Gate Valve

FREE-Valve’s Pneumatic Ceramic Double Disc Gate Valve is mainly used in feeding and dumping the dry powder and the transport pipeline, which not only adopt toughening ceramic as shut off and wearout 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 morewearresistancein process of opening and closing frequently, thereby, which guarantee the high requirements of sealing performance of this valve and long working time.

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 plate structure of the pneumatic ceramic double disc gate valve.
4. The valve has characteristics of good sealing performance, strong abrasion resistant, open and close easily.
