Two-way metal hard sealed ball valve is widely used in gas, petroleum, chemical, thermal, papermaking, metallurgy, electric power and other departments where the medium contains particles and fibers that are easy to scar.
Features
1. Two-way Metal Hard Sealed Ball Valve has novel design, simple structure and beautiful appearance.
2. With self-cleaning function, it can remove scale for the medium containing particles and fibers that are easy to scar, and the opening and closing is flexible.
3. There is a certain axial eccentricity between the sealing pair and the valve shaft, so the spherical surface and the valve seat quickly contact and separate when opening and closing, the friction coefficient is small, and the service life is long.
4. Two-way sealing performance can be installed in any direction, not controlled by the flow direction of the medium, with reliable sealing and stable performance.
5. The product has the characteristics of high temperature resistance, corrosion resistance, wear resistance, 90° rotation and small torque.
