Eccentric Hemisphere Valve

The eccentric hemispherical valve produced by Dazhong Valve Group is composed of main components such as valve body, eccentric sphere, main (slave) moving shaft, upper (lower) bushing, spherical crown, pressure ring, inner (outer) valve seat, etc. The worm gear mechanism drives the eccentric crankshaft to rotate 90° to realize the opening and closing of the valve, and plays the role of cutting off the medium. , so that the valve is not tightly closed and other problems. The valve has a unique boss design on the valve seat, which effectively protects the valve seat, especially suitable for water slag systems, etc. It is widely used in municipal sewage treatment, water supply and other fluid control systems.

• The valve disc is designed with eccentric rotation, the tighter the valve is, the tighter the valve is, and it can achieve bidirectional sealing and compensation for the wear of the sealing surface;

• The disc eccentric design enables the disc surface and the valve seat to be quickly clutched when opening and closing, reducing wear and opening and closing torque;

• After the valve is fully opened, the valve disc is located on the side of the valve cavity, which reduces the medium flushing and flow resistance;

• When installed horizontally, there will be no debris deposited in the lower part of the valve cavity;

• The sealing surface is made of hard alloy surfacing, and the inner cavity and valve disc can be sprayed with a wear-resistant layer;

• Simple structure, quick opening and closing.
