Based on the product’s anatomical diagram, the core advantage of the JH Floating Ball Valve stems from its precise floating seal structure: the valve body employs a precisely calculated guide groove design to ensure accurate ball displacement under medium pressure; the floating seal mechanism creates a self-reinforcing seal at the outlet end through the ball’s automatic clamping action; the flexible seat system uses a special composite material that maintains its elastic recovery capability even at a sealing pressure ≥45MPa; and the anti-blowout valve stem and bottom support form a complete force transmission path, ensuring stability under high-pressure conditions. The dissection reveals that the clearances of each component are precisely calculated, enabling this floating ball valve to achieve optimal sealing performance and reliability within a compact structure.
Diverse drive solutions meet the needs of economical and precise control in medium and low voltage operating conditions.
