◆Flanged Hard-Sealed Butterfly Valve
Categories：
Triple Eccentric(Offset) Butterfly Valve
Flanged Butterfly Valve
⚙️ Flanged Hard-Sealed Butterfly Valve
38 years of valve manufacturing experience | Specializing in water treatment and large-diameter valves | Offering project‑specific customization
Flanged hard-sealed butterfly valves utilize Flanged Connection Structure and Metal Hard-Seal Design , suitable for piping systems with stringent requirements for sealing performance, wear resistance, temperature resistance, and long-term operational reliability.
Compared with soft-seal butterfly valves, hard-seal designs offer superior resistance to high temperatures, wear, and media erosion, and can be customized with appropriate valve bodies, discs, stems, and sealing materials to suit various operating conditions.
Widely used in Water treatment, wastewater treatment, water supply, industrial circulating water, seawater systems, and energy and industrial piping 。
🔧 Core Product Features
✓ Metallic hard-sealed structure
It employs a metal-sealed design, offering excellent wear resistance, temperature resistance, and resistance to media erosion, making it suitable for long-term operating conditions.
✓ Flanged connection
It features flanged end connections, enabling compatible installation with standard pipe flanges. Its robust design ensures reliable performance and facilitates easy installation, disassembly, and subsequent maintenance.
✓ Reliable sealing performance
Through a well‑designed valve disc and seat configuration, stable shut‑off sealing is achieved, meeting the sealing requirements of various industrial piping systems.
✓ Low-friction design available
Depending on the valve’s design, an eccentric configuration may be employed to minimize friction between the valve disc and the sealing surfaces during opening and closing, thereby reducing seal wear.
✓ Suitable for large-diameter pipelines
Available in a variety of diameters and pressure ratings, it is suitable for large-scale water supply, wastewater treatment, and industrial pipeline projects.
✓ Multiple drive modes
Configurable Manual, worm-gear, electric, and pneumatic actuators , meeting diverse automated control requirements.
💧 Applicable Industries
Water Treatment | Wastewater Treatment | Water Supply Engineering | Industrial Circulating Water | Seawater Systems | Energy | Chemical Industry | Industrial Piping
