Ceramic rotary valve is mainly used for power plant dry ash system warehouse pump or economizer feeding valve opening and closing, but also suitable for mine, petrochemical plant, cement plant and other wear, corrosion of the dust media feeding opening and closing.

Mingrui ceramics factory direct sale ceramic rotary valve, product quality is reliable, can be customized, ceramic rotary valve has good sealing performance, strong wear resistance, open and close flexible, no card ash and ash phenomenon.

Performance characteristics of ceramic rotary valve:
1. Flexible opening and closing, reliable sealing
2. Can replace double gate valve, bell cover valve, no maintenance without maintenance
3. The nominal pressure of pneumatic actuator is 0.4-0.6mpa, and the nominal pressure of valve is 1MPa
4. Pneumatic transmission, non-standard customizable

Manufacturing precision:
Ceramic Rotary Valve precision machining dimension can be up to 0.001mm, the minimum pore diameter can be machined 0.07mm, the minimum tolerance of the inner hole can be machined 0.005mm, the highest tereity can be up to 0.004mm.
