📐 Welded Hard-Sealed Butterfly Valve
Categories：
Triple Eccentric(Offset) Butterfly Valve
🔧 Welded Hard-Sealing Butterfly Valve | Welded Hard-Sealing Butterfly Valve
38 years of valve manufacturing experience | Specializing in water treatment and large-diameter valves | Offering project‑specific customization
Welded hard-sealed butterfly valves utilize Welded joint structure + metal hard-seal design , suitable for industrial piping systems with stringent requirements for sealing performance, temperature resistance, pressure resistance, and long-term operational stability.
Compared with conventional soft-seal butterfly valves, hard-seal designs are better suited to higher temperatures, higher pressures, and more demanding operating conditions, making them ideal for… Water treatment, wastewater treatment, industrial circulating water, water supply systems, energy, chemical industry, and other industrial pipelines 。
⚙️ Core Product Features
✓ Welded connection
The valve body is welded to the pipeline, resulting in a compact design that reduces the installation space required by conventional flanged connections, making it suitable for specific industrial pipelines and high-reliability piping systems.
✓ Metal hard seal
It employs a metal-sealed design, offering excellent wear resistance, temperature resistance, and resistance to media erosion, making it suitable for service conditions that demand high sealing reliability.
✓ Low-leakage design
A well‑designed valve disc, seat, and sealing configuration helps reduce leakage in the closed position and enhances the long‑term operational reliability of the valve.
✓ Suitable for large-diameter pipelines
It can be designed and configured according to pipe diameter, pressure rating, process fluid, and installation conditions, making it suitable for large-scale industrial and water‑treatment projects.
✓ Multiple drive modes
Configurable Manual, worm-gear, electric, or pneumatic actuators , meeting the requirements of on-off control and automatic regulation systems.
✓ Supports non-standard customization
Different options can be provided according to project requirements. Valve body, valve disc, valve stem, seals, and actuator configuration 。

🏭 38 years of valve manufacturing experience
Since 1988 Dedicated to valve manufacturing.
We have long been dedicated to water treatment and industrial pipeline valves, with a particular focus on manufacturing. Eccentric butterfly valves, large-diameter butterfly valves, hard-sealed butterfly valves, flow‑and‑pressure regulating valves, rotary ball valves, and seawater butterfly valves 。
From product selection and material configuration to manufacturing, we can assist customers in validating their choices based on actual operating conditions:
• Nominal diameter DN
• Pressure rating PN / Class
• Operating temperature
• Media Type
• Sealing requirements
• Drive Type
• Installation method
• Material and Corrosion-Resistance Requirements
We do not simply offer a single valve model; instead, we tailor an appropriate valve solution to suit the specific operating conditions of each project.
🔩 Optional Configuration
Connection method: Welded type
