DELCO MYD-DCF Hydraulic Fluorine-Lined Cast Steel Flanged Butterfly Valve for Strong Acid & Alkali Service
The DELCO MYD-DCF is a flanged, fluorine-lined cast steel butterfly valve built for aggressive chemical media such as sulfuric acid, hydrochloric acid, and chlor-alkali. Its bolt-on flange design handles higher pressures and allows fast inline removal, while a MYD gear-and-rack hydraulic actuator delivering 28–25,340 Nm from a 2.0–16 MPa supply provides ±5° fine adjustment, bottom manual override, and top-mounted switches for remote control. Fully compliant with API 609 / ASME B16.5 / EN 1092-1 and ISO 9001 / CE.
Size Range: DN50–DN600
Selection Manual
Key Features
The DELCO MYD-DCF combines a WCB cast steel body with PTFE/F46 fluorine lining (DN50–DN600) and a flanged, bolt-on structure for higher-pressure service, driven by the MYD hydraulic actuator (2.0–16 MPa, 28–25,340 Nm) for corrosion-proof flow control in acid, alkali, and oxidizing lines — with precise ±5° control, manual override, remote-ready switching, and ISO 5211 mounting.
✅Fluorine-lined corrosion protection — WCB cast steel body with PTFE/F46 liner withstands sulfuric acid, hydrochloric acid, alkalis, and oxidants up to 180°C, serving long life in chemical and chlor-alkali plants.
✅Flanged, high-pressure & easy-maintenance — Bolt-on flange connection (ASME B16.5 / EN 1092-1) supports higher pressure classes and quick inline removal without cutting the pipeline — ideal for maintenance-intensive plants.
✅High-torque MYD hydraulic actuator — A MYD gear & rack actuator with integrated-piston carbon steel cylinder delivers 2.0–16 MPa supply pressure and 28–25,340 Nm output (MYD32–MYD160), sized for DN50–DN600 flanged service.
✅Precise control & global-standard ready — ±5° fine-tuning via adjustment bolts, bottom manual override, and top-mounted limit/travel/proximity switches for remote operation; built to API 609 with ISO 5211 mounting and ISO 9001 / CE certification.
