1-General Standard Name
Stainless steel integrated precision sampling regulating valve (with pressure gauge). Alternative names: Steam-water sampling constant flow control valve, high pressure instrument micro flow regulating valve.
2-Structural Features
Material: Integrally forged 316L stainless steel, high pressure and corrosion resistance, matching Russian GOST working conditions.
Structure: Extended long rod design with manual regulating handwheel, precision pressure gauge and side sampling port, dedicated modular regulating unit for sampling system.
Principle: High-precision conical plug realizes stepless micro flow regulation; built-in pressure gauge displays pipeline pressure visually.
3-Application
1.Thermal Power / Captive Power Plants (Core Mainstream Market)
A standard valve used in centralized steam-water sampling and analysis systems in power plants. Each feedwater, boiler water, and steam sampling circuit requires one valve, used together with coolers and constant pressure valves to precisely control the medium flow entering water quality analyzers. Hundreds of refinery captive power plants and regional CHP plants across Russia maintain stable annual demand for both new projects and spare parts, making it a high-frequency repeat-purchase product.
2.Petroleum Refining & Natural Gas Processing Industry
Used in online chromatographic analysis systems for process media in refinery catalytic cracking units, hydroreforming units, LNG plants, and natural gas purification plants, providing precise flow regulation for trace oil & gas and acidic gases to ensure stable analytical data.
National-level energy projects such as Yamal LNG and the Amur Gas Processing Plant require these valves as mandatory supporting components for EPC contractors. After the withdrawal of European and American brands, Chinese-made 316 stainless steel regulating valves have gained a significant cost-performance advantage.
3.Coal Chemical & Fine Chemical Industry
Used in corrosive process medium sampling pipelines for synthetic ammonia, methanol, and coking plants to stably regulate the flow entering online analyzers and prevent pressure fluctuations from impacting precision sensors. It is a core component in chemical automation monitoring systems.
4.Environmental Monitoring & Laboratory Analysis Industry
Widely used in industrial flue gas emission monitoring systems, high-pressure reaction gas circuits, and laboratory chromatographic analysis equipment. Russia’s local industry can only manufacture ordinary low-pressure valves, while import dependence for precision sampling regulating valves exceeds 85%, leaving substantial market competition opportunities.
