DK67-PB Lightweight Corrosion-Resistant Pneumatic UPVC Butterfly Valve
DELCO's Pneumatic PVC Butterfly Valve is built with a polyvinyl chloride (UPVC) body, offering a lightweight and highly corrosion-resistant solution for controlling acidic or alkaline liquids. Equipped with an AT series actuator , it provides reliable ON/OFF or adjustment control, making it suitable for chemical water treatment and laboratory drainage systems.
Features
Superior Corrosion Resistance and Quick, Reliable Operation
✅ Exceptional Corrosion Resistance:The valve body is made of PVC, making it lightweight and highly resistant to corrosion. It is ideal for controlling corrosive acids or alkalis. Other available body materials include UPVC, CPVC, PPH, and PVDF to meet different chemical application needs.
✅ Versatile Connection and Sealing: The valve supports either clamp or flange connection (DIN/ANSI standard). It utilizes EPDM or FPM soft seals, which are resistant to weak acids and bases, ensuring zero leakage.
✅ High Ingress Protection Actuator: The integrated pneumatic actuator (AT Series ) has a protection level of IP65, reliably supporting both two-position (switch) and proportional (adjustment) control.
✅ Optimal for Chemical Applications: The valve is widely applied in scenarios requiring chemical resistance, such as chemical water treatment, electroplating tank solution control, and laboratory drainage systems.
✅ Compact and Quick Operation: The product features a lightweight and small-sized design , utilizing a center-line resilient seal structure and bushings to ensure minimal friction for quick starting and closing.
