Worm-gear Eccentric Hemisphere Valve

Perfect equipment to control dusty gas, fluid containing large particle, two-phase fluids and powder solid medium
Apply to transport powder spraying, milling system and dust precipitation system
Straight through:<ul>
Made for single direction sealing and eccentric structure
Suitable for two-phase fluid medium in coal powder spraying and alumina conveying system
Valve core deviates from seat when opening
Makes impossible for flow to be jammed by accumulated ash</ul>
Easy to open and close:<ul>
No contact between valve core and valve seat when opening
Cause little torque and free turning
Squeezing and cutting between semi-sphere and seat removes fouling and adhesives on sealing surfaces when closing
Assures a tight and reliable sealing</ul>
Eccentric structure of sealing surface enables an automatic repairing of spherical wearing:<ul>
Good sealing
Long working lifespan
Safety and reliability
No leakage will occur due to wearing even after long period of service</ul>
Valve is a kind of hard sealing structure:<ul>
Material of sealing set is anti-abrasive alloy of Cr-Mo-V
Made by special treatment
Valve core apart from direct flushing
Lessening abrasive effect and lengthening service lifespan</ul>
