Key Features
True Double Block
Two independent balls provide complete upstream and downstream isolation, ensuring zero leakage.
Built-In Bleed Port
Quickly release cavity pressure and easily check for leaks—safer and more reliable.
Trunnion-Mounted Stability
Trunnion-mounted design reduces torque and keeps sealing performance consistent under high pressure.
Compact DBB Design
Dual block and bleed integrated in one body—fewer connections, less chance of leaks, and easier installation.
Easy Maintenance
Bolted body design allows fast inspection and simple component replacement, saving time and effort.
Fire-Safe & Anti-Static Stem
Built to prevent static build-up, withstand fire, and eliminate stem blowout risks-perfect for oil, gas, and critical pipelines.
