Introducing the Pneumatic Eccentric Semi Ball Valve This is a cutting-edge, high-performance valve expertly developed using the most advanced technology available. Engineered on the robust foundation of an O type ball valve, it effectively overcomes the challenges associated with the conveyance of 'solid-liquid' and 'solid-gas' two-phase mediums.
Exceptional Benefits
1. Featuring a straight-through valve body design, this valve ensures that when fully opened, the fluid flows linearly, thus reducing energy loss to a minimum when compared to traditional valve counterparts.
2. Effortlessly Operable: Thanks to the innovative design where the valve disc moves away from the valve seat without direct contact, the starting torque is significantly lower than that of an O type ball valve, making it exceptionally easy to operate.
3. The double eccentric structural design guarantees a perfect seal, allowing the semi-ball valve to close with absolute precision and tightness.
4. When the valve is in the closed position, the wedging force efficiently eliminates foreign material, bestowing it with outstanding anti-scaling capabilities.
