Pneumatic Ceramic Double Disc Gate Valve
Mechanical Parts Fabrication Services
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.
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 has characteristics of good sealing performance, strong abrasion resistant, open and close easily.
