High-Pressure
Double Block & Bleed Valves
Jeetan Double Block & Bleed (DBB) Valves are designed to provide reliable isolation by combining two block valves and one bleed valve into a single compact unit.
These valves allow simultaneous isolation of upstream and downstream pressure while enabling safe venting of trapped pressure through the bleed port. This ensures enhanced safety during maintenance, calibration, and system shutdown.
- Dual isolation with integrated bleed function
- Compact single-body design reduces leak paths
- High-pressure capability up to 10,000 PSI
- Available in multiple configurations (BNB, NNN, Flanged)
- Optional anti-tamper and locking arrangements
- Bubble-tight shut-off performance
Configurations Available
1. BNB (Block-Needle-Block):
- Primary and secondary isolation using ball valves
- Central needle valve for vent/bleed
- Suitable for general isolation applications
2. NNN (Needle-Needle-Needle):
- Two needle valves for isolation and one for vent
- Provides fine control and precise sealing
- Ideal for instrumentation systems
3. Flanged DBB (Flange × NPT):
- Designed for direct mounting on pipelines or vessels
- Available in multiple pressure classes
- Suitable for process industries and critical applications
The compact design reduces installation space, minimizes leak paths, and improves system integrity in high-pressure applications.
Design & Construction
Jeetan DBB valves are manufactured using high-grade materials such as SS316, Inconel, Duplex, and exotic alloys for demanding environments.
The design ensures minimal leakage points, high structural integrity, and reliable operation under high pressure and temperature conditions.
Available seat options include PTFE, PEEK, and metal-to-metal sealing for different application requirements.
Target Applications
- Oil & Gas industry
- Petrochemical plants
- Instrumentation lines
- Hydraulic systems
- Process control systems
- Pressure isolation and venting applications
