DELCO DK67-DCF Pneumatic Lined Flange Butterfly Valve – PTFE+FEP, Anti-Corrosion

✅Double Layer Fluorine Lining: Features a thick PTFE+FEP lining on both the valve body and disc, completely isolating metal parts from the medium to resist strong acid mists and electroplating waste gas.

✅Secure Flanged Connection: The Double Flanged (ANSI 150 / DIN PN16) design provides rigid structural support, making it safer and more stable than Pneumatic Wafer Butterfly Valves for large pipe sizes and end-of-line service.

✅Precision Pneumatic Modulation: Integrated with a pneumatic actuator and Valve Positioner, enabling accurate flow regulation via 4-20mA signals, ideal for critical chemical dosing and exhaust scrubbing.

✅Zero Leakage Performance: The resilient backing of the liner ensures ANSI Class VI (Soft Seal) bubble-tight shutoff, preventing hazardous gas leakage in phosphate fertilizer and chemical plants.

✅Large Diameter Capability: Specifically engineered for larger pipelines where stability is paramount, preventing seal deformation and leakage common in plastic valves under load.
