Pneumatic UPVC plastic butterfly valves offer advantages such as strong corrosion resistance, wear resistance, and lightweight valve bodies. They feature a centerline valve structure for easy disassembly and simple maintenance, making them suitable for water, air, oil, and corrosive chemical liquids.
Pneumatic plastic butterfly valves enable direct on/off control via compressed air. When fitted with a valve positioner receiving a 4-20mA signal, they can regulate parameters such as medium flow rate, pressure, and temperature. Widely adopted across industries including pure water and potable water pipeline systems, drainage and sewage systems, brine and seawater pipelines, as well as acid, alkali, and chemical solution systems, their quality has earned recognition from a broad user base.
