Oil and gas pipeline industry

Pipe valves are designed and manufactured in accordance with API 6D and ISO 14313, and can be used in transmission lines designed in accordance with ASME B31.3, ASME B31.4, ASME B31.8, or equivalent standards. YAAO Valves manufactures a range of straight-through pipeline isolation valves designed to minimize flow pressure drop, including fully open check valves (such as ear-mounted ball valves), straight-through pipeline gate valves, and fully open swing check valves.

Mining

Mining and metallurgy (ore dressing + smelting) have high demands for valves that can withstand harsh conditions during ore dressing and smelting processes. Valves should be wear-resistant, corrosion-resistant, and have excellent flow performance. Ya'ao Valves manufactures knife gate valves, metal-seated ball valves, double/triple eccentric butterfly valves, and angle valves made of carbon steel, stainless steel, Harris alloy, and titanium for the mining industry.

Offshore and onshore mining industries

Marine upper system features: platforms, FPSOs, and FLNGs. Harsh operating conditions: corrosive environments, high pressure, salty air and water, deep water, etc. YAAO Marine Specialized Valves: API-certified ball valves, butterfly valves, gate valves, globe valves, and check valves with high stability, reliability, and safety performance.

Coal chemical industry

YAAO products are widely used in wear-prone conditions (such as gasification, catalysts, etc.), low-temperature conditions (such as air separation, ethylene cracking, low-temperature methanol washing, etc.), high-temperature conditions (such as P91 pipelines), low-leakage conditions (toxic and hazardous media), oxygen conditions (air separation, gasification, etc.), shut-off valves (emergency shut-off, high-frequency shut-off, pulse, slag locking, oxygen shut-off), and other harsh conditions. YAAO's business has expanded to cover the entire industrial chain, including coal direct liquefaction, indirect liquefaction, natural gas, and other chemical production.

Refining and petrochemical industry

YAAO Valve can provide various types of valves required for refining and petrochemical applications, which typically involve high temperatures, high pressures, dirty services, and corrosive fluids. YAAO Valve has become a qualified supplier to several large oil companies and has participated in multiple large-scale refining and petrochemical projects.

Liquefied natural gas industry

Cryogenic valves typically handle liquefied gases, such as liquefied natural gas, which must operate at extremely low temperatures. YAAO Cryogenic includes gate valves, globe valves, check valves, ball valves, and butterfly valves, designed to comply with BS-6364 standards and extensively tested at -196°C (helium tested in a liquid nitrogen bath).

Electric power industry

Traditional steam thermal expansion into turbines accounts for approximately 80% of total power generation and will remain at a high level over the next decade. YAAO Valve can provide a full range of power generation valve requirements (conventional and improved thermal cycles, including renewable resources and related applications). With comprehensive professional certifications such as fire protection, low leakage, and SIL, we can meet the needs of many customers in the power industry.

Water treatment industry

The water treatment industry has been seeking ways to maximize water resource sharing to ensure adequate water supply. YAAO Valve provides complete solutions for various water treatment applications: efficient desalination, transportation, treatment, and distribution of water; shut-off of industrial water cooling circuits; wastewater treatment, hydropower generation, etc.

Chemical industry

The chemical industry is characterized by product diversification, complex processes, high pollutant emissions, and high toxicity levels. YAAO Valve: Compliant with international standards such as TA-Luft, ISO 15848, and API 624 for unorganized emissions, meeting the most stringent environmental regulations.
