Widespread Application:

1. Coal-fired power plant dry ash system (including inlet and outlet valves, breather valves, balance valves, exhaust valves, clog discharge valves, and ash unloading valves).

2. Bulk material conveying systems for industries such as cement, chemicals, metallurgy, papermaking, etc.

3. Various worn media are used for opening and closing purposes in pipelines.

Pneumatic oscillating ceramic feed valve, also known as pneumatic wear-resistant rotating valve, pneumatic ceramic wear-resistant oscillating valve, and silo pump feed valve, operates by rotating the valve plate through a shaft, resulting in a rotational motion during the valve's on-off action. The piston rod and sealing material of the pneumatic actuator do not come into direct contact with the medium, significantly extending the lifespan of the pneumatic actuator. Additionally, the innovative and unique design effectively addresses the issue of material leakage at the shaft seal of similar valves. The valve body is made of precision cast steel, the sealing material uses wear-resistant and high-temperature fluororubber seals or flexible graphite, and the sealing surface between the valve plate and seat is a wear-resistant and toughened ceramic structure, with a smooth surface and hardness up to 88HRC. This solves the problem of the sealing surface being easily eroded and having a short lifespan due to material abrasion, with a service life up to 5-10 times longer than that of valves made from ordinary materials. It provides users with ideal performance and economic benefits, greatly enhancing the safety and stability of equipment operation.
