Metal Seated Eccentric Half Ball Valve
【Product Overview】
The BQ647H-16C Pneumatic Eccentric Half Ball Valve is a high-performance control valve designed for abrasive and high-solid media, such as coal powder, slurry, ash, and particles. Its eccentric structure ensures that the ball and seat separate upon opening to reduce friction, and tightly wedge together upon closing to ensure zero leakage.
With a metal-to-metal hard seal, robust WCB body, and pneumatic actuator with positioner or FRL (Filter-Regulator-Lubricator) set, it’s ideal for severe service conditions in power generation, cement plants, and pneumatic conveying systems.
