The metal seal eccentric half ball valve

The metal seal eccentric half-ball valve series is a new type of valve that has been developed in China for nearly a decade and is used in the pipeline of solid powders that are not suitable for the whole ball valve.

The metal-sealed eccentric semi-ball valve in our company is eccentric, and its advanced nature is dissected from the seat in the open and closed hemisphere, which reduces the operating torque. And protected the cover. More importantly, the power on the stem directly provides a seal to the sphere. (the operating force on the whole ball valve is only for spin 90.) so this metal sealing off the seal of the semi-ball valve is more manageable. The hand is more reliable. In order to meet the requirements of the industry, such as power station and steel gas, it is necessary to close the flow of solid particles in the pipe, and to close the gas flow in the flow of the solid powder. This technology is very demanding, and our newly developed metal seal eccentric semi-ball valve series can be applied to this condition.

Our company has improved on this point, the body, the ball, the seat seal face, all sprayed on the tungsten carbide layer, the hardness of the HRC70, the resistance is strong. The second seat structure adopts adjustable floating elastic structure, which ADAPTS to the corresponding pressure level. More important is the ability to scrape the surface of the surface of the sphere, and when the valves are closed, the solid particles flow and the gas can be turned off at the same time.

The metal seal of our company is an eccentric semi-ball valve with several control systems, such as worm wheel, electric and pneumatic, which can be connected to the central control center. User requirements. The connection flange can be designed and manufactured by foreign standards and various stainless steel materials. This valve is more suitable for other liquids and gases, the pipes of various media.
