Manual Eccentric Semi Ball Valve

Manual Eccentric Semi Ball Valve

1.Structure design, eccentric structure: adopt special eccentric design, sphere gyration center (means the valve rod center) existing eccentric distance with the sphere center and valve base center. Sphere firstly revolve on position then tightly press the valve base when opening, reduce the sealing surface rub and wear, extend the working life. The semi sphere design, the sphere is semi sphere shape, small contact surface with the valve base, reduce the operating torque under the premise that guarantee sealing, make the manual operation more light and convenient. And the semi sphere structure favour to the medium pass through smoothly, reduce the turbulence and pressure loss. Valve rod and drive: the valve rod and sphere rigidity connected, reliable transmit torque. Manual operating part generally configured handle wheel or handle, the operating methods are straight stroke or revolve type, clear and discriminate operating position, comfortable operating hand feeling, convenient to the…
