DK56-PB Electric UPVC Butterfly Valve for Pure Water and Chemical Control
The DELCO Electric UPVC Butterfly Valve is a lightweight, highly corrosion-resistant automated valve combining a plastic body (UPVC/CPVC/PPH/PVDF) with an electric actuator. Ideal for corrosive media, it supports both on/off (switch) and modulating (4-20mA) control. It is extensively used in pure water, sewage, and acid/alkali systems where metal valves are unsuitable.
Features
Corrosion-Free Plastic Construction and Integrated Smart Control
✅Superior Chemical Resistance: Constructed from advanced thermoplastics (UPVC, CPVC, PPH, or PVDF), the valve body and disc are highly resistant to acids, alkalis, salts, and pure water media, ensuring an exceptionally long, corrosion-free operational life.
✅Electric Automated Control: Features an integrated electric actuator that can utilize a 220 V power supply for simple on/off switching or accept analog signals (4-20 mAor 1-5 V DC) for precise flow modulating control via a built-in servo module.
✅Lightweight Thermoplastic Design: The plastic construction significantly reduces weight and simplifies installation compared to metal alternatives, making it an efficient choice for large-scale water treatment and chemical piping systems.
✅Reliable and Tight Sealing: Uses resilient elastomers like EPDM or FKM for the seat and O-rings, providing dependable sealing and ensuring tight shutoff against various corrosive liquids.
✅Versatile Material Options: Offers a choice of plastic materials (UPVC, CPVC, PPH, PVDF) for the body and Stainless Steel stems (304, 316, 401) to ensure the best chemical compatibility for diverse industrial applications.
