WCB Stainless Steel Eccentric Hemispherical Valve Half Ball Valve
Product introduction:
Eccentric hemispherical valve is a valve with a size offset between the center axis of the valve body and the center axis of the hemisphere, and only a sealing pair is installed on one side of the valve body. Eccentric hemispherical valve is a type of valve that uses a sphere with a circular channel as the opening and closing element, and rotates around the center-line of the valve body to achieve opening and closing.

Product features:
1. Valve core of eccentric half ball valve is located in the ball chamber when valve is opened, where the fluid flows directly, resulting in a large flow area, low flow resistance, and low pressure loss. The medium will not deposit in the chamber of the valve body.
2. Eccentric half ball valve is suitable for high flow velocity mediums, straight through flow channels, and the tightly fastened eccentric fixed crankshaft is suitable for high flow velocity without vibration and noise.
3. Eccentric half ball valve with small operating torque, and the opening and closing can be completed by rotating 90 degrees, making the operation light.
4. Eccentric half ball valve with tight sealing, double eccentric metal hard sealing, does not affect opening and closing after scaling, which is the most significant advantage of a hemispherical valve.
5. Eccentric half ball valve with long service life, wear-resistant sealing pair, with compensation, easy maintenance, and adjustable or replaceable valve seat.
6. Eccentric half ball valve is widely applicable to pipelines such as water, sewage, containing small solid particles, steam, gas, natural gas, and oil products.
