Full Bore Eccentric Hemisphere Valve

The full bore eccentric hemisphere valve is composed of the valve body, eccentric sphere, main (slave) moving shaft, upper (lower) shaft sleeve, ball crown, pressure ring, inner (outer) valve seat and other main components. It drives the eccentric crankshaft to rotate 90 ° by rotating the worm gear mechanism to open and close the valve, which plays the role of cutting off the medium. It solves the problem that slurry, mixed flow liquid, dust and other media settle, scale and block in the pipeline transportation in industrial production, The valve can not be closed tightly.

The eccentric crankshaft is adopted for the full bore eccentric hemisphere valve, which makes the valve have good self sealing performance. The connection form between the valve and the pipeline is flange connection. The valve has a unique boss design on the valve seat, which effectively protects the valve seat. It is especially suitable for water slag system, etc. It is widely used in municipal sewage treatment, water supply and other fluid control systems.
