Modular double block & bleed (DBB) valve

Modular double block & bleed (DBB) valve

Our valves are engineered for reliable performance across a wide range of oil & gas, chemical, and petrochemical operations—from production and processing to transportation and distribution. Designed in compliance with global standards such as API 6D, API 6A, ASME B16.34, ISO 14313, ISO 10423, and ISO 17292, these valves are suitable for system isolation, pressure control, flow measurement, and more.

Ideal for instrument drain, chemical injection, and sampling in smaller size ranges, these valves offer tight shut-off, robust pressure handling, and exceptional material compatibility for harsh operating environments. Available in NPS 1 to 12 (DN 25–300) with pressure ratings up to ASME 2500, they are suitable for a wide temperature range of -58 to 392°F (-50 to 200°C).

Multiple end connection options, including RF, RTJ, BW, and SW, allow seamless integration into existing systems. Material selection and design configurations are fully customizable to meet project-specific requirements.
