These valves are primarily used in oil, gas, and water systems where preventing backflow is critical, particularly in high-temperature or high-pressure environments like petrochemical plants and power stations.
Our valves are manufactured according to API 594, API 6D, and ASME B16.34, ensuring they meet the strictest global safety and performance requirements.
Yes, with the selection of appropriate materials (such as ASTM A352 LCB/LCC), these valves can operate in temperatures as low as -196℃.
Stellite 21 is a cobalt-based alloy that provides exceptional hardness and resistance to erosion, corrosion, and galling, significantly extending the valve's operational life.
Each valve undergoes 100% chemical analysis, mechanical tests, DPT, hydraulic shell and seal tests, and low-pressure air tests per API 598 and API 6D.
Absolutely. We offer a wide range of materials including Monel, Inconel, and Hastealloy (H-276) to ensure the valve can withstand highly corrosive industrial environments.
