Electric PVC Butterfly Valve for Highly Corrosive Chemical and Water Systems
The DELCO Electric PVC Butterfly Valve is an integrated unit combining a reliable electric actuator with a lightweight, highly corrosion-resistant plastic body (UPVC/CPVC). It is widely used in systems handling pure water, sewage, saltwater, and acid/alkali chemical solutions. The valve supports both simple on/off switch control and precise flow modulating control via 4-20mA signals, offering an efficient and durable solution for automated chemical processes.
Features
Corrosion-Free Plastic Construction and Integrated Smart Control
✅ Superior Chemical Resistance: Constructed from advanced thermoplastics (UPVC, CPVC, RPP, PVDF), the valve offers excellent resistance to virtually all corrosive liquids, including strong acids, bases, and salts, ensuring a long operational lifespan without metal contamination or degradation.
✅ Automated Modulating Control: Equipped with an integrated electric actuator, the valve can be controlled by a simple 220V power switch signal for basic on/off function, or by an analog signal (4-20mA or 1-5 V DC) when a built-in servo module is used for accurate proportional flow regulation.
✅ Lightweight and Easy Installation: The plastic construction results in a significantly lighter valve compared to equivalent metal alternatives. This simplifies transportation, handling, and installation, especially in large-scale piping systems for water treatment plants.
✅ Reliable and Tight Sealing: The valve utilizes high-performance seating and O-rings made from durable elastomers like NBR or EPDM. This combination provides dependable sealing against various liquids and ensures bubble-tight shutoff for non-critical applications.
✅ Versatile Application Profile: Due to its excellent corrosion properties, the valve is the ideal choice for pipeline systems in pure water, drinking water, drainage and sewage, saltwater, seawater desalination, and chemical solution transfer industries.
