Industrial Valve Overhaul, Hydrostatic Testing & Supply
Comprehensive reconditioning, precision seat lapping, high-pressure hydrostatic proof testing, and supply of industrial gate, globe, ball, check, butterfly, and control valves across the Middle East.
Turnkey Industrial Valve Overhaul & Pressure Testing
Certified reconditioning, precision seat lapping, high-pressure hydrostatic proof testing, and actuation calibration for critical process valves.
Gate, Globe & Check Valves
Flexible and solid wedge gate valves, globe throttling valves, and non-slam tilting disc check valves. Body cavity cleaning, stem polishing, packing replacement, and backseat testing.
High-Performance Ball & Butterfly Valves
Soft and metal-seated trunnion mounted ball valves (API 6D) and triple-eccentric metal-to-metal butterfly valves. Precision sphere polishing, seat ring replacement, and zero-leakage testing.
Control & Pressure Relief Valves (PSV)
Pneumatic diaphragm and piston actuated control valves, electro-pneumatic smart positioners, and spring-loaded pressure relief valves calibrated and certified against set pressures.
Hydrostatic & Seat Leakage Testing
High-pressure hydrostatic shell proof testing, high-pressure liquid seat testing, and low-pressure pneumatic air seat leakage testing with automated bubble counters and digital chart recording.
Seat Lapping & Stellite Hardfacing
Portable and stationary orbital lapping machines restoring sealing flatness to within 2 light bands (0.6 µm). Plasma transferred arc (PTA) stellite welding for severe service trims.
Own Foundry Valve Body & Trim Casting
When obsolete valve bodies or internal trims are cracked or washed out, our own casting foundry pours replacements in WCB, CF8M, Duplex, or Bronze—slashing procurement down to days.
Uncompromising Quality, Safety & Environmental Standards
Certified Integrated Management System (IMS) governing every overhaul, machining operation, dynamic balancing cycle, and field mobilization across the UAE and GCC.
Calibrated Metrology
Precision inside/outside micrometers, bore gauges, dial test indicators, and coordinate measuring machines calibrated to national standards.
Rotor Dynamic Balancing
Dual-plane dynamic balancing up to 3,000 kg executed in strict accordance with ISO 21940 / API 610 vibration criteria.
Non-Destructive Testing
Dye penetrant inspection (DPI) and magnetic particle inspection (MPI) performed by certified Level II technicians on critical rotating elements.
Comprehensive QA Dossier
Every overhaul is accompanied by a full technical inspection report, balancing certificate, dimension record, and metallurgy test sheets.
Workshop Capabilities & Engineering Thresholds
Certified dimensional envelopes, balancing payload limits, and metallurgical testing standards active at our Jebel Ali overhaul facility.
