Metal-Seat Flanged Ball Valves, with their unique structure and operational mechanism, have become a pivotal component in fluid control systems. Their defining feature lies in achieving full closure with a mere 90-degree rotation and requiring minimal operating torque. The fully parallel internal cavity design ensures minimal resistance to media flow, maximizing the efficiency of straight-through passageways.
Originally designed primarily for on/off operation, modern iterations now enable throttling and flow control functionality. Their compact structure, user-friendly operation, and ease of maintenance make them suitable for diverse media, including water, solvents, acids, and natural gas-even under harsh conditions involving oxygen, hydrogen peroxide, methane, and ethylene. The valve body is available in monolithic or modular configurations, further expanding their application versatility.
