Ball Valve Series Overview Ball valves are essential components in fluid control systems, widely used across industries such as oil and gas, water treatment, chemical processing, and HVAC. Their simple yet robust design ensures reliable shut-off, minimal pressure drop, and long service life. This series includes a variety of ball valves tailored to different applications, materials, and pressure ratings. Design and Operation Ball valves operate via a rotating spherical disc (the "ball") with a bore through its center. When the valve is open, the bore aligns with the pipeline, allowing fluid flow. A 90-degree turn of the handle or actuator closes the valve by positioning the bore perpendicular to the flow, blocking passage. This quarter-turn operation enables quick and efficient control. Types of Ball Valves 1. Floating Ball Valves: The ball is suspended by the valve seats, suitable for low-to-medium pressure applications. 2. Trunnion-Mounted Ball Valves: The ball is anchored at the top and bottom, ideal for high-pressure or large-diameter pipelines. 3. Full-Port vs. Reduced-Port: Full-port valves have a bore matching the pipe diameter, minimizing flow restriction, while reduced-port valves are more compact but create slight pressure loss. 4. Multi-Port Valves: Feature multiple flow paths for diverting or mixing fluids. Materials and Construction Ball valves are constructed from materials like stainless steel, brass, carbon steel, PVC, or exotic alloys to suit corrosive, high-temperature, or sanitary environments. Seals are typically made from PTFE, nylon, or elastomers for tight shut-off and chemical resistance. Applications - Oil & Gas: Handles crude oil, natural gas, and refined products. - Water Systems: Used in potable water, wastewater, and irrigation. - Chemical Processing: Resistant to aggressive media like acids and solvents. - HVAC: Controls refrigerants and heating fluids. Advantages - Quick Operation: 90-degree turn for full open/close. - Low Maintenance: Fewer moving parts reduce wear. - Bubble-Tight Seal: Prevents leakage when closed. - Versatility: Adaptable to various pressures, temperatures, and media. Selection Considerations When choosing a ball valve, factors like pressure rating, temperature range, fluid compatibility, and actuation method (manual, pneumatic, electric) must be evaluated. In summary, the ball valve series offers efficient, durable solutions for diverse fluid control needs, ensuring safety and performance across industries.
