These high-specification gate valves are specifically engineered to withstand deep pressure fluctuations and severe environmental variations, making them the leading configurations deployed across regional water and transmission networks.
As the largest landlocked nation globally and the primary economic powerhouse of Central Asia, Kazakhstan hosts exceptionally demanding environments for pipeline engineering. The intersection of massive resource extraction—ranging from oil fields in the Caspian Basin to coal mines in Karaganda—with extreme geographic and climatic parameters requires high-integrity piping systems. Heavy industries in Kazakhstan operate in climates experiencing temperature differentials of over 85°C between summer peaks and sub-zero winter lows (down to -50°C in capital regions). Standard municipal and chemical valves fail under these severe thermal transitions, resulting in casting cracks, seal shrinkage, and dangerous line blockages.
Furthermore, Kazakhstan's strategic positioning within the Eurasian transport corridor demands compliance with both regional GOST standards (EAC / TR CU 010/032 regulations) and Western standards such as DIN and ANSI. Infrastructure development across cities like Astana, Almaty, and Atyrau requires components that bridge the transition between legacy Soviet infrastructure and modern, digitized processing facilities. Gate valves—representing the critical isolation barrier in high-pressure distribution lines—must offer long-term reliability and zero maintenance, preventing catastrophic outages in municipal district heating and oil distribution loops.
Specifically tested cast WCB/WCC steel and low-temperature carbon steels (LCC/LCB) maintain impact energy integrity at temperatures below -50°C.
Full alignment with Technical Regulation of the Customs Union TR CU 010/2011 and TR CU 032/2013 for pressurized equipment safety.
Manufactured under strict ISO 9001:2015 frameworks with full EN 10204 3.1 material traceability, assuring high reliability.
Our comprehensive industrial gate valve portfolios provide tailored engineering benefits for each of the region's prominent resource-extraction and processing industries:
The Caspian onshore and offshore fields (Tengiz, Kashagan, Karachaganak) extract high-pressure, sulfur-heavy crude and gas mixtures. In these sour service environments, valves must comply with NACE MR0175/ISO 15156. Our Cast Steel WCB and SS316 flanged gate valves feature hard-faced Stellite 6 wedges to prevent sulfide stress cracking. Built to withstand up to PN64 and ANSI Class 600 pressure ratings, they offer bubble-tight isolation for upstream processing and trans-Eurasian transport pipelines.
District heating is essential for urban survival during Kazakhstan's winter seasons. Resilient-seated gate valves featuring EPDM-vulcanized wedges are critical for local water utilities. Our non-rising stem valves, configured in accordance with DIN F4 and F5 standards, prevent soil-shifting and freezing damages, ensuring reliable municipal water supply lines even under sub-zero conditions.
Kazakhstan is a major global producer of copper, zinc, and uranium (Balkhash, Jezkazgan, Ust-Kamenogorsk). Ore slurry pipelines carry high concentrations of abrasive suspended solids. Standard gate valves quickly suffer seat erosion under these conditions. Our custom metal-seated WCB gate valves, equipped with hard seats and solid wedges, offer excellent abrasion resistance, reducing maintenance downtime.
Refineries in Pavlodar, Atyrau, and Shymkent process corrosive chemical process fluids. Our CF8 and CF8M stainless steel rising stem gate valves offer excellent chemical resistance. They feature high-purity PTFE or graphite packing rings to minimize fugitive emissions and ensure compliance with strict environmental regulations.

For temperatures down to -50°C, standard ASTM A216 WCB cast steel is not recommended due to brittle transition risks. We recommend specifying ASTM A352 LCB or LCC (Low-Temperature Carbon Steel), which are Charpy V-notch tested to assure mechanical impact toughness down to -46°C and -50°C. For corrosive media at low temperatures, CF8 (SS304) and CF8M (SS316) offer excellent performance.
DIN F4 and DIN F5 (defined under EN 558-1 Series 14 and 15) designate face-to-face dimensions. DIN F4 represents the short pattern (e.g., DN100 is 190mm), saving installation space. DIN F5 represents the long pattern (e.g., DN100 is 350mm). Long-pattern F5 valves are typically used in deeper bury or high-pressure installations to reduce stress on the adjacent piping.
Our resilient seat wedges are fully vulcanized with high-durability EPDM rubber using high-pressure injection molding. This prevents the elastomer from peeling or deforming under flow velocity. The resilient seat achieves bubble-tight shutoff (Class A leakage rate) with low operating torque.
Yes. Our heavy-duty gate, butterfly, and check valves comply with TR CU 010/2011 (Machinery Safety) and TR CU 032/2013 (Equipment Operating under Excess Pressure). We supply full engineering portfolios including pressure test certificates, material chemical analysis reports (EN 10204 3.1), and operating manuals.
NRS (Non-Rising Stem) valves require less vertical space, making them ideal for underground buried water services and chambers. OS&Y (Outside Screw & Yoke / Rising Stem) valves expose the stem thread, allowing easy identification of the valve position (open/closed) and protecting the stem thread from the line fluid, making them suitable for oil, gas, and chemical refinery plants.
For high-pressure designs (such as PN64 or ANSI Class 600 WCB/WCC valves), we apply a Stellite 6 hard-faced overlay on the seat ring and wedge face. Precision CNC grinding and lapping ensure a metal-to-metal match, conforming to API 598 testing criteria for Zero-Leakage performance.
For slurry applications, we offer customized gate valves with hardened solid wedges (high chromium steels or Stellite faced) and integrated flushing ports. This prevents slurry buildup in the body cavity and reduces wear during operation.
Standard gate valves are maintained in inventory for rapid dispatch. Custom casting runs or specific material configurations (e.g., LCC body with special stem extensions) typically require 30 to 45 days for manufacturing, pressure testing, and documentation preparation.
