DBB Valve, also known as Double Block and Bleed Valve, is widely used in oil and gas, petrochemical, and pipeline systems to ensure safe and reliable isolation. A DBB valve provides two independent sealing barriers with a bleed function in between, allowing pressure release and leakage verification. This design enhances operational safety, reduces the risk of cross contamination, and minimizes downtime during maintenance. Manufactured from high quality materials and designed to meet international standards, DBB Valve solutions offer excellent sealing performance, durability, and long service life under high pressure and high temperature conditions.
