This bevel gear drive knife gate valve provided by our company is quality regulating device that enjoys a shorter valve body and light weight. The sealing face of its valve seat, free from the erosion caused by the media and quite tight-fitting, bears uniform pressure and could sweep grains and tars on the sealing face away when it is closed, quite helpful for drainage and avoidance of media leakage. Given this fact, this slurry control valve is suitable for coal gas pipelines where there are dusts or tars.
