2·3·5 Valve
Manifolds.
Engineered to mount directly on every major DP and pressure transmitter — Rosemount, Yokogawa, Honeywell, Emerson, Endress+Hauser. Manufactured and pressure-tested in Jubail, KSA.
What is an instrument manifold?
A manifold valve consolidates the isolation, equalisation and venting functions needed by a pressure or differential pressure (DP) transmitter into a single compact body. Instead of plumbing three or five separate valves into the impulse lines, the manifold bolts straight to the transmitter — one assembly, one mount, one source of truth for material certs.
The result: faster hook-up, tighter footprint, fewer leak paths, and a defined service procedure for calibration, zero-checks and start-up. Standard configurations are 2-valve (gauge / static pressure), 3-valve (DP transmitter — block, block, equalize) and 5-valve (DP transmitter with vent and additional block-and-bleed).
Three core configurations. Pick yours.
Each configuration is offered with NPT, BSPT, BSPP or socket-weld process ends, and IEC 61518 transmitter flange — so it lands on whatever your specification calls for.
2-Valve Manifold
One block valve plus one vent / test valve. Mounts on single-port pressure gauges and static pressure transmitters. The simplest manifold in the line — and the workhorse of any well-instrumented plant.
3-Valve Manifold
Two block valves plus one equalize valve. The standard hook-up for differential pressure transmitters: isolate both impulse lines, equalize for zero-check, then re-open in the correct sequence to protect the diaphragm.
5-Valve Manifold
Two blocks, two vents, one equalize. Adds individual vent & bleed valves to each impulse line — for in-place calibration, sample-out and instrument removal without breaking process containment. Often specified for hazardous, sour, or critical service.
Direct mount, remote mount, or hybrid.
Every ICCL manifold is offered in three mounting variants. Specify in your RFQ — we ship with the correct adapter, gasket and mounting bolts.
Direct Mount
Manifold bolts straight to the transmitter via IEC 61518 flange pattern. Eliminates impulse piping, reduces leak paths, and is the lowest-cost installation.
Remote Mount
Manifold installed away from the transmitter — connected by impulse tubing. Used where the transmitter must be located away from heat, vibration or hazardous zones.
Hybrid (with Pigtail)
Direct mount with siphon / pigtail accessory for steam services. Combines compactness of direct mount with thermal protection for the transmitter diaphragm.
Drop-in compatible. Every major OEM.
ICCL manifolds use the IEC 61518 bolting pattern with standard 54 mm impulse-line spacing — meaning they fit virtually every DP and pressure transmitter sold into the Kingdom. Specific cross-references on request.

Specifications & materials.
All ICCL manifolds ship with EN 10204 3.1 material certificates as standard. Higher-grade documentation (3.2, NACE, PMI) available on request.
Where the manifolds go.
Every transmitter on the plant has a manifold beneath it. We supply the Kingdom's largest energy and process operators — and the EPC contractors building the next wave of giga-projects.

Stock + Custom
SS316 standards ex-stock. Exotic alloys typically 4–6 weeks.
We standardised on ICCL 3-valve manifolds across two refinery upgrade projects. The IEC 61518 fitment is dimensionally perfect — every Rosemount transmitter mounts first-time, no shimming, no tubing.
What's the difference between a 2-valve, 3-valve and 5-valve manifold?
3-valve = two blocks + one equalize. The standard hook-up for differential pressure (DP) transmitters.
5-valve = two blocks + two vents + one equalize. Adds individual vent/bleed valves on each impulse line — for safer calibration and instrument removal in critical or sour service.
Will ICCL manifolds fit a Rosemount or Yokogawa transmitter?
What's the correct operating sequence for a 3-valve manifold?
Zero-check: close blocks, open equalize, read transmitter zero, close equalize, re-open blocks.
Shutdown: close blocks, open equalize, vent before removing transmitter. The equalize-first / open-blocks-second sequence prevents one-sided overpressure on the DP cell.
