Petroleum

Petroleum

YAO valves can provide various valve types required for refining and petrochemical applications, which typically involve high temperature, high pressure, dirty services, and corrosive fluids. YAO Valve has become a qualified supplier for multiple large oil companies and has participated in multiple large-scale refining projects.

Natural Gas

Natural Gas

Low temperature valves typically handle liquefied gases, such as liquefied natural gas that needs to operate at extremely low temperatures. YAO Low Temperature 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 gas tested in liquid nitrogen bath).

Chemical Engineering

Chemical Engineering

The characteristics of the chemical industry are: diversified products, complex processes, large emissions of pollutants, and high levels of toxicity. YAO Valve: Applicable to international standards such as TA Luft, ISO15848, API 624 unorganized emission standards, etc., meeting the strictest environmental regulations.

Power Engineering

Power Engineering

The use of traditional steam thermal expansion to enter turbines accounts for about 80% of the total electricity generation, and will continue to maintain a high level in the next decade. YAO Valve can provide a comprehensive range of power generation valve requirements (conventional and improved thermal cycles, including renewable resources and related applications). Complete professional certifications such as fire prevention, low leakage, SIL, etc. can meet the needs of many customers in the power industry.

LNG

LNG

Low temperature valves typically handle liquefied gases, such as liquefied natural gas that needs to operate at extremely low temperatures. YAO Low Temperature 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 gas tested in liquid nitrogen bath).

Offshore Platform

Offshore Platform

Characteristics of offshore upper system: platform, FPSO, and FLNG. Adverse operating conditions: corrosive environment, high pressure, salty air and water, deep water, etc. YAO Marine Special Valves: API certified ball valves, butterfly valves, gate valves, globe valves, and check valves with high stability, reliability, and safety performance.

Metallurgy

Metallurgy

YAO products are widely used in wear and tear 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 harmful 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. YAO's business has extended to the entire industry chain, including direct coal liquefaction, indirect liquefaction, natural gas, and other chemical production.

Water supply and drainage engineering

Water supply and drainage engineering

The water treatment industry has been seeking ways to maximize water resource sharing to ensure adequate water supply. YAO Valve provides complete solutions for various applications of water treatment: using efficient methods for seawater desalination, transportation, treatment, and distribution of water; Cutting off the industrial water cooling circuit; Wastewater treatment, hydropower generation, etc
