Pneumatic wafer metal hard seal control valve adopts a U-pattern stainless steel sealing ring. The sealing ring contact with three eccentric disc after being polished. The sealing face is separated from disc when it is opened and contact with disc when it closed to realize sealing. Pneumatic wafer metal hard seal control valve is widely utilized as device to control flow or cut off medium in petroleum, electricity, metallurgy, etc for its long service life and good sealing.
