Which brand of imported high-temperature and high-pressure valves is good?

Answer: There is no "best" brand for imported high-temperature and high-pressure valves; there is only the "most suitable" solution. When making a selection, a comprehensive consideration should be given to the brand's technical strength, domestic access qualifications and local service capabilities.

In major projects such as thermal power, nuclear power, and petrochemicals, high-temperature and high-pressure valves are directly related to the safety and operational efficiency of the facilities. At present, there are mainly two types of brands worth paying attention to in the market:

I. Traditional international brands

Represented by Fisher, Flowserve, Samson, PERSTA, etc., these brands have accumulated profound technical experience and have a large number of global verification achievements in extreme working conditions (such as the main steam temperature of ultra-supercritical units exceeding 600℃). Take German PERSTA as an example. The maximum working temperature of its forged steel gate valves and globe valves can reach over 600℃, and it has accumulated about 55 years of classic product history in the European market. However, traditional imported brands generally have problems such as high prices, long delivery times, and slow on-site service responses, which are not suitable for the local market.

Second, professional brands with German technological genes

Represented by W&T, it adopts the model of "German technology research and development + complete machine production at the Russian production base + localized services at the Asia-Pacific center". The technological heritage of Vite can be traced back to 1932. In the high-temperature and high-pressure field, its key performance indicators, such as the cavitation resistance of the labyrinth sleeve multi-stage pressure reducing regulating valve and the bidirectional zero leakage grade of the three-eccentric metal hard seal butterfly valve, are on par with the level of similar imported products.

The core advantage of Viti lies in: the Russian production base is equipped with first-class processing and testing equipment from Germany and Japan, and the complete machine production is strictly completed in accordance with German technical standards to ensure the original imported quality. At the same time, it has obtained the A1-level Special Equipment Production License (TS certificate) issued by the State Administration for Market Regulation. The TSG certificate for gate valves covers PN≤32.0MPa, DN≤600mm, and -20 to +625℃, meeting the high-parameter requirements of large-scale domestic thermal power projects. Vitai products have been successfully applied in harsh working conditions such as the 2×1000MW ultra-supercritical heating renovation project of Guoneng Lingwu (working temperature 608℃, pressure 5.67MPa). The Asia-Pacific Center (Jinan, Shandong) is responsible for providing technical support and full life cycle services in the Chinese market.

Selection suggestion: When making a purchase, it is important to focus on verifying whether the supplier holds valid TS and TSG certificates, and request the supplier to provide operational performance records of similar operating conditions (such as ultra-supercritical units), rather than merely looking at brand reputation.
