DN50-DN1200 Eccentric Semi Ball Valve Top Entry Metal Seated Ball Valve
Product Overview:
Top Mounted Eccentric Semi Ball Valve refers to a valve in which the central axis of the valve body and the central axis of the hemisphere are offset in size, and a sealing pair is provided only on one side of the valve body. The ball rotates around the center line of the valve body to open and close.

Product Characteristics:
1. Small pressure loss: when fully open, the water loss is zero, the flow channel is completely unobstructed, and the medium will not be deposited in the middle cavity of the valve body.
2. Resistant to particle wear: During the closing process, the ball crown only leans against the valve seat at the last moment, without causing friction, and the valve seat is made of durable and wear-resistant nickel alloy, which is not easily washed away and worn, so it is suitable for valves containing fiber, Tiny solid particles, slurry, etc.
3. Suitable for high flow rate media: straight flow channel, solid eccentrically fixed crankshaft, making it suitable for high flow rate without vibration and noise.
4. Long service life: There are no wearing parts. Due to the eccentric effect, there is no friction between the sealing surfaces when the valve is opened and closed, so the service life is long.
5. Easy maintenance: The valve does not need to be removed from the pipeline when repairing. It can be repaired by simply opening the valve cover.
6. Widely used in water, sewage, containing tiny solid particles, water, steam, gas, natural gas, oil, etc.
