Widely used:
1. Dry ash system in thermal power plants (used as inlet and outlet valves, vent valves, balance valves, exhaust valves, blockage removal valves, and ash discharge valves).
2. Bulk material conveying systems in industries such as cement, chemical engineering, metallurgy, papermaking, pharmaceuticals, etc.
3. Various media with wear and tear are used for opening and closing on pipelines.
Pneumatic swing ceramic feed valve, also known as pneumatic wear-resistant rotary valve, pneumatic wear-resistant ceramic swing valve, and bin pump feed valve, drives the valve plate to move through the rotating shaft, making the motion force when the valve is opened and closed rotate. The piston rod and sealing packing of the pneumatic actuator do not come into direct contact with the medium, greatly extending the service life of the pneumatic actuator. At the same time, the novel and unique design effectively solves the problem of material leakage at the sealing position of similar valve shafts. The valve body is made of precision cast steel, and the sealing filler is made of wear-resistant and high-temperature resistant fluororubber seals or flexible graphite. The sealing surface between the valve plate and valve seat is made of wear-resistant and toughened structural ceramics, with a smooth surface and a hardness of up to 88HRC. This solves the problem of the sealing surface being easily eroded by material erosion and low lifespan. The service life is 5-10 times longer than that of ordinary material valves, bringing ideal usage effects and economic benefits to users, Greatly improves the safety and stability of equipment operation.
