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.
