Fully Welded Ball Valve

Fully Welded Ball Valve

The fully-welded ball valve produced by ONERO adopts forged material, welded body, instead of bolts and nuts, to avoid any potential leakage from body. ONERO’s fully welded ball valve

enhances sealing reliability and has relatively small maintenance requirements. One of the great outstanding features of the fully welded ball valve is its long service life, which can extend up to 30 years. The fully welded construction reduces the need for frequent maintenance, making it a cost-effective and reliable solution.

Features and Benefits

- Simple Structure Good tightness: The valve is designed with a straightforward structure, providing good sealing and requiring smallest torque for operation.
- Emergency Sealant Injection: The valve is equipped with an emergency sealant injection system that provides additional sealing in case of seat or stem leakage.
- Cavity Pressure Self-Relief: The self-relieving feature prevents pressure buildup within the valve cavity, ensuring safe and efficient operation.
- Fire-Safe and Anti-Static Design: The fully welded ball valve includes fire-safe features and an anti-static mechanism, enhancing safety in hazardous environments.
- Anti-Blowout Stem: The stem is designed to prevent blowout, ensuring operational safety under high-pressure conditions.
- DBB and DIB Functionality options: The valve seat provides Double Block and Bleed (DBB), DIB-1, and DIB-2 functions for enhanced isolation and safety.
- Underground Installation Capability: Designed for underground applications, the fully-welded ball valve prevents corrosion of interior parts, ensuring long-term service life.
