Double Block
& Bleed Valves.
One compact body. Two isolation valves. One bleed valve in between. Manufactured, hydro-tested and shipped from our facility in the Kingdom of Saudi Arabia — built to ASME B31.3 with full traceability.
What is a double block & bleed valve?
A double block and bleed valve (DBB) integrates two block valves and a single bleed valve into one compact body. The two block valves isolate the process line from both upstream and downstream pressure, while the central bleed valve vents the cavity between them — giving operators a verifiable, zero-leak isolation point.
Replacing three discrete valves with a single DBB body cuts weight by up to 60%, reduces leak paths from twelve to four, and simplifies hook-up for instrument lines, pressure transmitters, gauges, sample points and chemical injection systems.
ICCL manufactures DBB valves at our Jubail facility for the Kingdom's oil & gas, refining, petrochemical and power generation sectors — and ships across the GCC with ex-stock availability on standard configurations.
Five standard configurations. Engineered to spec.
All configurations available in 316/316L stainless, Monel, Hastelloy, Inconel, and duplex on request.
2-Way DBB
Two ball or needle blocks with center bleed. Standard for instrument hook-up and pressure transmitters.
Monoflange DBB
Direct-mount flanged body eliminates conventional 3-valve manifolds. Best for DP transmitters.
DBB with Sample Point
Integrated sampling port for closed-loop hydrocarbon and chemical sample collection.
Needle DBB
Two needle blocks for fine throttling and high-pressure gauge isolation up to 10,000 psi.
Cartridge DBB
Replaceable cartridge design for in-line maintenance without removing the body from the line.
Specifications & materials.
Standard ranges below. Special metallurgy, exotic alloys and custom pressure ratings on request — full material certs (3.1 / 3.2) supplied with every order.
Where ICCL DBB valves go to work.
Trusted across the Kingdom's energy and process infrastructure — from upstream wellheads to downstream refining, and into the new petrochemical mega-projects across NEOM, Yanbu and Jubail Industrial City.
Upstream Oil & Gas
Wellhead instrument hook-up, pressure transmitters, X-mas tree gauge isolation, sour-gas service.
Refining & Petrochem
DP flow measurement, level transmitters on columns, chemical injection points, flare headers.
Power & Desalination
Steam drum sample lines, boiler feed water, IWPP instrumentation, MED/MSF condenser hook-ups.
Pipelines & Terminals
Custody transfer skids, metering stations, pig launcher/receiver isolation, tank farm pressure pickup.
Five reasons engineering teams in KSA specify ICCL.
Made in the Kingdom
100% manufactured in Jubail. No import lead time, no customs delays.
Aramco & SABIC Vendor
Pre-qualified and approved supplier on major Kingdom AVL programmes.
Stock Programme
Standard configurations ex-stock. Same-day dispatch from our Jubail warehouse.
Engineered to Spec
In-house design team. We build to your P&ID, not from a fixed catalogue.
Full Traceability
Material certs, hydrotest reports, PMI & heat numbers — supplied with every valve.
Switching our DBB supply to ICCL cut our valve lead time from sixteen weeks to three days. Quality docs match every line item — no more chasing mill certs through three layers of distribution.
