Medium Type: Water, Acids, Alkalis, Chemicals, Corrosive Liquids and Process Media
The DELCO MYD‑DCF Hydraulic Fluorine‑Lined Cast Steel Flanged Butterfly Valve is a heavy‑duty industrial flow control solution specially engineered for highly corrosive working conditions. Constructed with high‑strength cast steel WCB body, full fluoropolymer (PTFE/FEP/PFA) lining for all wetted components, integrated hydraulic quarter‑turn actuator and standard flanged connection, this hydraulic lined butterfly valve delivers reliable on‑off and throttling performance for aggressive chemical media. It effectively isolates corrosive fluid from metal substrate, avoiding rust and medium contamination, widely adopted for chemical processing, wastewater treatment, petrochemical and metallurgy projects.
Key Features
✅Full Fluorine‑Lined Anti‑Corrosion Performance
Body, disc and seat are fully lined with premium PTFE/FEP/PFA fluoroplastic, completely separating cast‑steel metal parts from corrosive fluids. Resists strong acids, strong alkalis, oxidants and organic solvents, avoids electrochemical corrosion, greatly extends valve service life compared with ordinary metal butterfly valves.
✅Robust Cast Steel Body & Standard Flanged Connection
High‑quality cast steel WCB body provides excellent mechanical strength, pressure and vibration resistance. ANSI / DIN standard flanged end ensures stable pipeline connection, better tightness than wafer‑type valves, suitable for large‑diameter, heavy‑duty industrial piping systems.
✅Stable Hydraulic Quarter‑Turn Actuation
Matched high‑performance hydraulic actuator realizes 90‑degree quick opening & closing, output torque stable, resistant to pressure fluctuation. Supports remote automatic control, suitable for heavy‑load working condition where pneumatic actuators cannot provide enough torque.
✅Bidirectional Zero‑Leakage Bubble‑Tight Sealing
Precision‑machined fluorine‑lined disc and seat form soft‑seal pair, achieves ANSI Class VI bubble‑tight shut‑off, bidirectional sealing capability. Prevent leakage of toxic, volatile corrosive medium, meet industrial safety and environmental protection requirements.
✅Low Operation Torque & Easy Maintenance
Smooth fluoroplastic surface reduces friction torque. Replaceable liner and seal components simplify on‑site maintenance, lower overall operation cost for plant Client. Compact butterfly‑valve structure saves installation space for skid‑mounted equipment.
✅Wide Working Parameter Compatibility
Supports PN10 / PN16 pressure rating, wide temperature range, multiple size options DN40‑DN1200. Customizable lining material, flange standard and hydraulic control function for project‑specific requirements.
Primary Applications
- Chemical Processing: Strong acid & alkali transport, chemical dosing, reaction loop pipelines.
- Wastewater & Environmental Protection: Desulfurization, corrosive sewage treatment, electroplating waste liquid system.
- Petrochemical & Metallurgy: Corrosive medium cut‑off and throttling control.
- Pharmaceutical & Fine‑Chemical: Anti‑contamination fluid control for aggressive process fluids.
Operating Conditions
- Used for fluid shut-off and throttling regulation.
- Supports intermittent or continuous operation and frequent cycling.
- Suitable for remote automatic control applications requiring high torque where pneumatic actuation lacks sufficient power.
Note: Long-term operation in a partially open (throttling) state with media containing significant amounts of hard particles is not recommended.
Selection of Hydraulic Actuators
The MYD series quarter-turn hydraulic actuator is an ideal hydraulic actuator developed by DELCO, incorporating advanced international technology. It features a long service life, high output torque, a compact and rational structure, rugged durability, and an aesthetically pleasing design. It supports programmable and microprocessor-based control, enabling modulating control or rapid on/off functions. Suitable for various quarter-turn valves—such as ball valves, butterfly valves, and plug valves—it is widely used in industrial pipeline control systems across sectors including petrochemicals, metallurgy and papermaking, nuclear power, boiler equipment, and military marine applications.
The MYD series compact hydraulic actuators are designed and manufactured in strict accordance with standardization, miniaturization, and modular series principles, ensuring high versatility and ease of installation and maintenance. The bottom mounting interface complies with the ISO 5211 standard, facilitating easy valve installation. An opening indicator provides a clear visual display of "Open" and "Close" positions and is easily removable to allow for manual wrench operation. Stroke adjustment bolts mechanically limit the actuator's rotation angle, enabling on-site adjustment of the open and closed positions; standard products offer a ±5° adjustment range at both the 0° and 90° positions. The MYD series represents a new type of hydraulic actuator independently developed and manufactured by DELCO, holding a relevant technical patent (Patent No.: ZL201020225905.6).
