A: A double acting butterfly valve regulates flow using a rotating disc, operated by a pneumatic actuator that requires air supply for both opening and closing. It’s ideal for precise control in high-pressure systems like chemical processing or water treatment.
A: A double flange type butterfly valve has flanges on both ends for secure bolting between pipeline sections, ensuring leak-proof connections. This design suits high-pressure applications better than wafer or lug-style valves.
A: Yes, if constructed with materials like stainless steel or PTFE-lined components, double flanged butterfly valves resist corrosion. Material selection depends on the fluid’s chemical properties and operating temperature.
A: Regular inspection of seals, actuator function, and disc alignment is essential. Lubrication of the stem and periodic testing under pressure ensure longevity and reliable performance.
A: Double acting valves provide bidirectional control and faster response times, ideal for systems requiring frequent adjustments. Single acting valves rely on springs for return motion, limiting speed and precision in critical applications.
