DK67-PB Pneumatic UPVC Wafer Butterfly Valve for Chemical, Electroplating, and Lab Drainage Systems
DELCO's DK67-PB Pneumatic Wafer Butterfly Valve is designed with a body made of UPVC and other highly corrosion-resistant plastic materials, specifically for controlling acidic or alkaline liquids. It features a lightweight, simple structure with EPDM/FPM soft seals and supports clamp or flange connections. Equipped with a robust pneumatic actuator, this valve offers both ON/OFF and adjusting control options, making it an ideal automated solution for challenging fluid environments.
Features
Superior Corrosion Resistance and Automated Plastic Control
✅ Exceptional Chemical and Corrosion Resistance: The valve body is constructed from highly durable plastic materials (PVC, UPVC, CPVC, PPH, or PVDF), ensuring strong resistance to corrosion from concentrated acidic or alkaline liquids.
✅ Integrated Pneumatic Automation (ON/OFF & Modulating): Paired with an AT Series pneumatic actuator, the valve supports both simple switch (ON/OFF) control and can be fitted with a positioner for precise flow adjustment (modulating control).
✅ Sanitary and Application-Specific Sealing: Utilizes EPDM or FPM soft seals, which offer superior resistance to weak acids and bases, maximizing performance and lifespan in chemical and sanitary applications.
✅ Ideal for Harsh Industry Applications: This valve is ideally suited for demanding fluid environments such as chemical water treatment, electroplating tank solution control, and laboratory drainage systems where metal valves are unsuitable.
✅ High Protection and Flexible Installation: The pneumatic actuator features an IP65 protection level for durability in harsh industrial settings. The valve utilizes a compact wafer-style connection, compatible with both Clamp or Flange (DIN/ANSI standard) types.
