Pneumatic Plastic Anti‑corrosion Butterfly Valve
The UPVC Pneumatic Butterfly Valve is a corrosion-resistant, lightweight valve designed for precise flow control in aggressive chemical environments (acids, alkalis, and salts), featuring UPVC construction for durability, pneumatic actuation for rapid 90° rotation, widely used in water treatment, chemical processing, and food/pharmaceutical industries due to its hygienic design and easy maintenance.
特点
- The material is hygienic and non-toxic, complying with national health standards. It features wear resistance, easy disassembly and simple maintenance, and is applied in various fields.
- Lightweight UPVC material has a specific gravity only 1/10 that of cast iron, enabling easy transportation and installation, and reducing costs.
- Made of UPVC, it provides excellent acid and alkali resistance, with a service life greatly extended compared with other piping systems.
- It features outstanding chemical corrosion resistance, is non-flammable and does not support combustion, eliminating fire safety concerns.
- It offers excellent strength and toughness. The inner wall is smooth and clean, making it difficult for dirt to adhere. It has low flow resistance and high flow efficiency.
