BB stands for Bolted Bonnet, allowing easy removal for maintenance, while FB refers to Forged Body or specialized bonnet structures. Our valves offer both depending on the pressure rating and application.
A flexible wedge can adjust slightly to compensate for thermal expansion or misalignment, ensuring a tighter seal in high-temperature or high-pressure industrial environments.
We primarily follow API 600, API 6D, and ASME B16.34 for design and manufacture, ensuring compatibility with global oil, gas, and water infrastructure.
Yes, our design temperature range goes down to -196℃, making them suitable for cryogenic services when specified with appropriate materials like ASTM A352 LCB/LCC.
Every valve undergoes 100% chemical analysis, DPT testing on castings, and rigorous hydraulic shell and seal tests according to API 598.
For large valves like the 42" model, we provide electric actuators (motorised) to ensure efficient and safe operation, though manual gear operators are also available.
