Description
1. Overview of Welded Butterfly Valve
The VTON welded butterfly valve, also known as a butt-welding butterfly valve, is designed for high-temperature and industrial-grade applications. With precision J-shaped elastic sealing rings and a three-eccentric metal seal structure, it offers exceptional durability and zero-leakage performance. Commonly used in heating networks, steam pipelines, and long-distance transmission systems, it is an ideal solution for regulating flow or shutting off fluid in critical pipelines.
Key Applications:
- Urban heating systems
- Metallurgical and power industries
- Petrochemical pipelines
- Municipal construction systems

3. Features
- Advanced Three-Eccentric Design: Ensures zero friction and zero leakage by allowing the butterfly plate and valve seat to make instant contact or separation.
- Durable Sealing Mechanism: Features a multi-layer stainless steel and flexible graphite seal, providing excellent performance in both high and low temperatures.
- Wear-Resistant Seal: Valve seat cone is hard-surfaced with EDCr-B-15 alloy, ensuring over 10,000 cycles without damage.
- Corrosion and High-Temperature Resistance: Made from premium materials for long-lasting performance under extreme conditions.
- Fire-Safe Design: Constructed entirely from fireproof materials for added safety.
- Self-Locking Functionality: The three-eccentric structure provides self-locking capabilities, preventing over-closure of the butterfly plate.
- Low Torque Operation: Streamlined butterfly plate reduces pressure loss, making it energy-efficient and easy to operate.
- Adjustable Seal: Facilitates precise assembly and easy maintenance.
- Versatile Control Options: Supports manual, electric, and pneumatic operation for seamless integration into automated systems.
- Flow Control and Shut-Off: Capable of completely shutting off media flow or regulating flow as needed.
