Pneumatic ceramic double gate valve

Pneumatic ceramic double gate valve is an industrial valve designed specifically for high wear and corrosive media, widely used in fields such as power, chemical, and mining. The following is a summary of its core information:

1、 Product Overview
Pneumatic ceramic double gate valves (such as Z644TC, PZ673H, etc.) adopt a structural ceramic sealing pair design, which achieves bidirectional sealing through a double gate structure and spring preload force. They have the characteristics of strong wear resistance, long service life, and good sealing performance. Its driving method is pneumatic actuator, supporting remote control, suitable for automated pipeline systems.
2、 Technical parameters
Nominal diameter: DN40~DN300 (some models can reach DN400).
Nominal pressure: PN0.6~PN16.0MPa (conventional models are PN1.0~PN2.5).
Applicable temperature: -40 ℃~425 ℃ (special models can reach 550 ℃).
Applicable media: dry ash, slurry, corrosive dust, etc.
3、 Structural characteristics
Ceramic sealing pair: made of alumina or silicon carbide ceramic materials, with wear resistance more than 10 times that of ordinary metals.
Double gate design: The support open structure achieves bidirectional sealing, and the gate rotates and polishes during opening and closing, extending the life of the sealing surface.
Pneumatic drive: Push rod direct cylinder actuator with high output torque, suitable for harsh working conditions.
4、 Application Fields
Power industry: dry ash system of thermal power plants, discharge valve of warehouse pumps.
Chemical/mining: transportation of corrosive media, slurry treatment.
Environmental engineering: sewage treatment, fly ash discharge.
