Zero friction metal seal ball valve, metal seal butterfly valve

Zero friction metal hard seal ball valve and butterfly valve is a new and unique structure which uses hydraulic bellow assembly to realize the friction of valve switch. The body seal ring is connected to a bellows assembly, which is connected to a hydraulic regulator. After the sealing ring of the valve body is removed from the sealing ring of the valve ball, the valve ball is straightened to 90 °, so as to achieve zero friction opening. After the valve is opened, the sealing ring of the valve body is driven by the hydraulic device to return to the original position. When the valve is closed, as in the above process, zero friction closure without leakage is achieved. This structure not only makes the ball valve butterfly valve switch resistance is small, also will not wear the sealing pair.

Novel design, unique structure, light and flexible operation. Large flow coefficient, small fluid resistance, high efficiency and energy saving.

Purpose: 

The ball valve, butterfly valve is a two-way sealing multi-purpose medium and low pressure valve, can be used as a cut-off valve, can also be used as a regulating valve, the adjustment range is 40 ° ~ 90 °, suitable for water supply and drainage, petroleum, chemical industry, metallurgy, thermal power, hydropower, light industry, medium and low pressure pipeline system.

Packing of Standard Packing:
