Features and Benefits

- Enhanced Sealing Performance

With a double block and bleed (DBB) structure, this valve provides good sealing and isolation capabilities. The cavity pressure self-relief mechanism prevents overpressure buildup within the valve body, ensuring operational safety.

- Fire-Safe and Anti-Static Design

Designed to meet API 607/6FA fire-safe standards, the valve ensures continued functionality even in fire conditions. Additionally, the anti-static device reduces the risk of electrostatic discharge, enhancing operational safety.

- Anti-Blowout Stem Design for Increased Safety
The valve stem is equipped with an anti-blowout design, preventing accidental stem ejection due to internal pressure. This feature enhances durability and ensures operator safety during use.

-Emergency Sealant Injection System
For added reliability, the Trunnion Mounted Ball Valve includes an emergency sealant injection system. This allows for secondary sealing in case of leakage, ensuring uninterrupted operation and extending service life.

- 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.
