Engineered for extreme thermal resilience (-40°C to +450°C), sour gas resistance ($H_2S$), and high-pressure isolation across Uzbek transmission grids and industrial complexes.
Under the national "Development Strategy of New Uzbekistan", the Republic of Uzbekistan is experiencing an unprecedented industrial renaissance. Driven by massive capital expenditure in natural gas processing, chemical synthesis, gold and copper mining, and municipal district heating modernization, Uzbekistan has emerged as Central Asia’s premier hub for heavy industrial development. Global engineering procurement and construction (EPC) contractors operating across regions such as Navoi, Almalyk, Kashkadarya, and Tashkent demand flow control components that adhere to strict international standards (API 6D, ISO 17292, ASME B16.34) alongside Eurasian economic compliance (GOST-U and EAC standards).
As one of the region’s largest producers of natural gas, projects such as the Gazli Underground Gas Storage Expansion, Ustyurt Gas Chemical Complex, and Uzbekneftegaz modernizations require fire-safe, double-block-and-bleed (DBB) trunnion ball valves capable of handling high pressure (ANSI Class 600 to 2500) and sour gas media laden with $H_2S$ and $CO_2$.
Navoi Mining & Metallurgical Combinat (NMMC) and Almalyk Mining & Metallurgical Combinat (AMMC) represent massive mineral extraction hubs. Processing abrasive quartz slurries, gold leaching solutions, and concentrate tailings demands metal-seated ball valves coated with High-Velocity Oxygen-Fuel (HVOF) Chromium/Tungsten Carbide to withstand continuous erosion.
Tashkent City modernization and regional municipal projects require robust, low-maintenance full-welded steel ball valves for direct-buried district heating mains and EPDM/PTFE-lined ductile iron ball valves for potability-certified water transmission networks.
Operating in Uzbekistan presents unique technical environmental challenges. Winter continental temperatures can drop below -30°C in the Ustyurt Plateau, while summer ambient heat routinely tops +45°C. Valve designs must compensate for extreme thermal contraction and expansion without sacrificing sealing integrity or operational torque.
For low-temperature natural gas and chemical service, standard ASTM A216 WCB steel is upgraded to ASTM A352 LCB/LCC cast steel or ASTM A350 LF2 forged steel. These materials undergo Charpy V-Notch impact testing at -46°C to prevent brittle fracture under high differential pressures. For corrosive fertilizer plants (Navoiyazot, Farg'onaazot), CF8M (SS316) and Duplex Stainless Steels (2205/2507) provide complete resistance to nitric and sulfuric acids.
Escaping volatile organic compounds (VOCs) and methane leaks pose environmental risks and financial losses. Our valve series features live-loaded, multi-ring Belleville spring packing systems certified to ISO 15848-1 Class AH and TA-Luft, guaranteeing stem seal tightness up to 100,000 operational cycles.
Soft PTFE seats degrade rapidly when exposed to media carrying quartz sand, mineral fines, or catalyst dust. Our severe-service ball valves utilize metal-to-metal seating featuring High-Velocity Oxygen-Fuel (HVOF) thermal spraying. Ball surfaces and seat rings receive a 0.3mm coating of Chromium Carbide or Tungsten Carbide, yielding surface hardness levels exceeding 68-72 HRC.
Modern gas compressor stations across Kashkadarya utilize automated pipeline management. Our pneumatic, hydraulic, and electric actuators are equipped with smart digital positioners, HART/Modbus communication modules, and SIL 3 safety integrity system ratings, allowing real-time diagnostic monitoring from centralized control centers in Tashkent.

Overland gas transmission lines operating across Uzbekistan require zero-leakage isolation. Our API 6D Trunnion-Mounted Ball Valves incorporate double block and bleed (DBB) capabilities, allowing operators to bleed pressure from the body cavity while the valve is under full line pressure. Standard features include secondary sealant injection fittings for emergency stem/seat sealing and fire-safe testing validation according to API 607 / API 6FA.
Consult Gas Sector EngineersIn uranium and gold extraction plants throughout Navoi, copper and mineral processing complexes in Almalyk, acidic leaching agents destroy conventional valves. We deliver Fully PTFE/PFA-Lined Ball Valves with WCB or SS304 outer bodies. The fluoropolymer lining is mechanically locked to the metal casing using die-cast dovetail grooves, preventing vacuum collapse under negative pressure conditions.
Consult Mining Sector EngineersNavigating regulatory frameworks is critical for project execution in Uzbekistan. Importing industrial valves into the country requires compliance with the Eurasian Customs Union (EAC) rules as well as Uzbekistan national quality standards managed by the Agency for Technical Regulation of Uzbekistan (Uzstandard).
All our exported industrial valve packages come complete with CU-TR 010/2011 (Machinery Safety) and CU-TR 032/2013 (Pressure Equipment Safety) certificates. We provide full support for local Uzstandard certificate of conformity issuance, avoiding customs hold-ups at border points like Keles, Sergeli, or Yallama.
Engineering documentation is supplied in dual-language Russian/English formats, including EN 10204 3.1 Material Test Reports (MTRs), hydro-test charts, NDT radiographic inspection reports, non-destructive magnetic particle test certificates, and complete installation/operation manuals.
Utilizing direct rail express routes from China (Lianyungang/Tianjin hubs) through Khorgos / Alashankou dry ports directly to Tashkent customs terminals, containerized shipments arrive in Uzbekistan within 12 to 18 transit days, offering faster supply chain turnaround compared to European suppliers.
As a leading Chinese valve OEM/ODM manufacturer, our production hubs integrate smart Industry 4.0 digital automation with end-to-end quality assurance. This setup provides Uzbek importers, state enterprises, and EPC contractors with tier-one European valve precision at direct factory cost efficiency.
Our facilities utilize multi-axis CNC horizontal machining centers, automatic sphere grinding lathes, and high-precision CMM measurement tools to maintain ball roundness tolerances within 0.005mm. This ultra-smooth spherical surface minimizes operational torque requirement by 25% while preventing premature seat wear.
Every manufactured ball valve undergoes 100% pressure testing according to API 598 and ISO 5208 standards before shipping. Shell hydrostatic tests are performed at 1.5 times nominal pressure, while high-pressure helium seat leak testing guarantees zero-bubble tightness for natural gas applications.
International EPC firms operating in Uzbekistan (such as Enter Engineering, Hyundai Engineering, Petrofac, and Sinopec) demand stringent vendor qualification processes. We streamline the entire valve procurement lifecycle—from initial technical bidding down to final site commissioning support.
We provide standardized or project-customized Inspection and Test Plans (ITP) detailing hold points for witness testing by third-party agencies such as SGS, TÜV, or Bureau Veritas.
All body castings, forgings, balls, stems, and seat materials are heat-number stamped and mapped directly to chemical composition and mechanical property mill test certificates.
Besides ball valves, we consolidate complete piping packages—including gate valves, globe valves, check valves, butterfly valves, and Y-strainers—into single, organized shipping containers to simplify site inventory handling.
