Key Specifications / Features
The Double Disc Gate Valve is designed for reliable flow control in various industrial systems. Available in sizes ranging from 2 to 16 inches (DN50-DN400), this valve operates at Class 150 LB pressure ratings. It features engineering ceramic sealing, offering enhanced durability and resistance to wear and corrosion. Equipped with a pneumatic actuator, it provides smooth, automated operation, ensuring efficient performance. The valve comes with flanged ends for secure and easy installation.
The Pneumatic Ceramic Double Disc Gate Valve is designed for feeding, dumping, and transporting dry powder materials. It features toughened ceramic materials for excellent wear resistance and a pressure self-sealing design with an auto-rotating valve disc. This construction ensures high sealing performance and longevity, even with frequent opening and closing operations.
Product Features
» Ceramic Sealing Pair: Made from structural ceramics, providing superior wear and flush resistance.
» Double Disc Structure: Achieves two-sided sealing, enhancing reliability.
» Spring-Loaded Self-Sealing: Springs between the double valve discs ensure bi-directional flexible preload pressure, enabling low-pressure bi-directional sealing and preventing dust clogging during operation.
» Rotational Disc Motion: Prevents ash deposition on the sealing surface, extending the valve's service life.
» Blow Sweep Port or Device: Available on the valve body to enhance performance based on operating conditions.
Product Application Areas
» The double plate ceramic pneumatic valve is primarily used in:
» Power Plant Ash Removal: Dry ash removal systems.
» Mineral Processing Plant: Selection and transportation of dry ore powder materials.
» Cement Industry: Conveying and discharging dry powder materials.
» Flour Mill: Flour conveying pipelines.
» Other Industrial Applications: Transporting high-wear media like powders or small solid particles, where hard particles and fibrous dirt are common.
» This valve serves as a cutoff and connecting medium channel, functioning as a discharge valve, balance valve, exhaust valve, and blockage valve for warehouse pumps. It can also be used as a pipeline switching valve and an ash discharge valve for ash storage. It offers good sealing performance, low starting load, minimal ash jamming and accumulation, strong wear resistance, and a long service life. Connection methods include flange and clamp, with manual, pneumatic, and electric driving modes available.
Scope of Product Use
