Double Block & Bleed Valves (DBB Valves)
Engineered for Maximum Safety. Designed for Complete Isolation.
Ped-lock Double Block & Bleed (DBB) Valves are precision-engineered to deliver superior isolation, pressure containment, and safe venting in critical process and instrumentation systems. By integrating two independent isolation valves with a dedicated bleed valve into a single compact assembly, Ped-lock DBB Valves significantly reduce potential leak paths, minimize installation space, and enhance overall system safety and operational efficiency.
Manufactured using premium-grade stainless steel, carbon steel, duplex stainless steel, and high-performance alloys, our DBB valves are designed to withstand the most demanding operating conditions while providing exceptional sealing integrity, corrosion resistance, and long-term reliability. Every valve is precision-machined and rigorously tested to ensure dependable performance in high-pressure and severe-service applications.
The Ped-lock DBB product portfolio includes Needle Type, Ball Type, Integral Body, Floating Ball, Trunnion Mounted, and Monoflange Double Block & Bleed Valves, offering complete isolation solutions for instrumentation, process control, oil & gas, petrochemical, offshore, LNG, power generation, chemical processing, and other critical industrial applications.
