PSV & SRV Calibration Services in Dubai & Across the UAE
TCAL delivers ISO 17025:2017 accredited PSV calibration services in Dubai, Abu Dhabi and across the UAE — testing, setting and certifying your pressure safety and safety relief valves so your plant's last line of defense is never in doubt.
Your Safety Valves Are the Last Line of Defense. We Make Sure They Fire.
A pressure safety valve that opens late — or not at all — turns a routine overpressure event into a catastrophic one. That's why PSV calibration services in UAE industry aren't a paperwork exercise: they're the difference between a controlled lift and a ruptured vessel. TCAL tests, adjusts and certifies pressure safety valves (PSV) and safety relief valves (SRV) to their exact set pressures, with every result traceable to international standards through our ISO 17025:2017 accredited laboratory.
As one of the most trusted names among SRV calibration companies in Dubai, we serve the plants where the stakes are highest — power stations, oil storage terminals, food processing lines, steam systems, air compressors and process skids. Our engineers verify set pressure, observe pop action, confirm reseating and seat tightness, then seal and tag each valve with a serialized certificate your auditor can trace end to end.
We deliver SRV calibration services both ways: on our test benches for the tightest control, or on-site when valves can't leave your facility — coordinated with your shutdown windows and permit systems. Pair the work with our pressure gauge calibration so the gauges guarding the same vessels carry matching certificates, or roll everything into an annual calibration contract and never chase a due date again.
From a single valve to a full plant population, clients choose TCAL for PSV calibration services in Dubai, Abu Dhabi and every emirate — see our complete PSV coverage across the UAE for emirate-by-emirate detail.
PSV vs SRV — What's the Difference?
The terms are often mixed up on site. Both protect against overpressure — but they behave differently, and each needs its own test approach.
PSV — Pressure Safety Valve
Rapid full-lift "pop" actionDesigned primarily for gases and steam. When system pressure hits the set point, a PSV snaps fully open almost instantly — dumping pressure fast to protect the vessel.
- Typical duty: boilers, air receivers, steam & gas systems
- We verify: set pressure, crisp pop action, blowdown & reseat
- Certified with serialized tag & wire seal after adjustment
SRV — Safety Relief Valve
Proportional, modulating reliefSuited to liquids and mixed-phase service. An SRV opens progressively in proportion to the overpressure, relieving just enough flow to hold the system safe.
- Typical duty: pumps, liquid process lines, thermal relief
- We verify: opening pressure, proportional lift & tight reseal
- Same accredited certificate & traceability as every TCAL job
Our Safety Valve Calibration Process
Bench or on-site, every valve goes through the same disciplined sequence.
Inspection & Data Capture
Nameplate data, set pressure, service and condition are recorded; the valve is visually inspected for damage, fouling and seat condition.
As-Found Testing
The valve is tested exactly as received — documenting whether it would have lifted at its set pressure. This is the number your auditor wants.
Adjustment & Verification
Set pressure is corrected, pop and reseat verified over repeat lifts, and seat tightness confirmed against the applicable standard.
Seal, Tag & Certify
The valve is wire-sealed, tagged with its serialized ID, and released with an ISO 17025:2017 traceable calibration certificate.
What Every TCAL Certificate Includes
A calibration is only as good as its paperwork. Every safety valve leaves our hands with a certificate built to survive your toughest audit — whether it's an insurer, a client QA team or a government inspector reading it.
- Valve identification, nameplate data & serialized certificate number
- As-found and as-left set pressure results
- Pop action, reseat pressure & seat tightness outcome
- Reference standards used, with unbroken traceability chain
- Test medium, ambient conditions & measurement uncertainty
- Technician, approval signatory & next-due recommendation

PSV Calibration Services in Abu Dhabi
For the capital's power, oil and industrial sector we provide SRV calibration services in Abu Dhabi both on-site and via collected bench work — among the few SRV calibration companies in Abu Dhabi's approved-vendor lists with ISO 17025:2017 accreditation behind every certificate.
SRV Calibration Services in Sharjah
Sharjah's manufacturers and utilities send valves to our bench or book our mobile team on-site — the choice of SRV calibration companies in Sharjah comes down to traceability, and ours is end-to-end.
SRV Calibration Services in Ajman
Ajman's factories and processing plants get collection, calibration and certified return in one loop — a level of service few SRV calibration companies in Ajman offer at this speed.
SRV Calibration Services in Fujairah
Fujairah's bunkering and terminal operations trust TCAL among SRV calibration companies in Fujairah for valve testing planned around vessel schedules — with east-coast mobilizations completed in a single visit.
SRV Calibration in Umm Al Quwain & Northern Emirates
UAQ and RAK facilities get the same accredited service as our Dubai clients — TCAL stands out among SRV calibration companies in Umm Al Quwain for reaching sites others treat as too remote.
PSV Calibration Services in UAE — Shutdown Support
Planning a turnaround? We deliver the PSV and SRV calibration services in UAE plants actually need at shutdown: batch testing during your window, day and night shifts, and every valve back before restart — capacity that few SRV calibration companies in UAE can match.
Why Plants Choose TCAL
Accredited results, as-found/as-left honesty, sealed and tagged valves, and certificates that pass audits first time — that's what keeps TCAL on approved-vendor lists across the UAE.
Safety Valve Calibration — Frequently Asked Questions
Most UAE plants test safety valves every 12 months, though the right interval depends on service severity, insurer requirements and your inspection code. Dirty, corrosive or high-cycle duties may need shorter intervals. TCAL states a next-due recommendation on every certificate, and our annual contracts track the schedule for you.
Both. Bench testing in our Dubai laboratory gives the tightest control and fastest batch throughput; on-site testing suits valves that can't be removed or plants mid-shutdown. Many clients combine the two — we'll recommend the right split when we see your valve list.
As-found is how your valve performed the moment it arrived — before any adjustment. As-left is its performance after correction. Recording both proves whether your equipment was protected during the previous interval, which is exactly what auditors and insurers look for. TCAL documents both on every certificate.
Yes. TCAL operates an ISO 17025:2017 accredited laboratory, and every safety valve certificate carries serialized identification, traceable reference standards and measurement uncertainty — the elements auditors check first. Our certificates are accepted across UAE industry, from oil terminals to food processors.
Yes. Batch programs are our specialty: valves are collected or received against a manifest, tested in priority order, sealed, tagged and returned before your restart date — with day and night shifts during turnaround season.
All of them. We provide PSV and SRV calibration across Dubai, Abu Dhabi, Sharjah, Ajman, Ras Al Khaimah, Fujairah and Umm Al Quwain — on-site or through our Dubai laboratory. Call +971 56 858 2626 for a same-day quotation.
