Seek recommendations: Which domestic valve brands are suitable for use in high-temperature and high-pressure environments?
Thread Content
I have worked in waste-to-energy plants for many years and come across numerous brands of valves, but I haven’t found any whose quality is particularly good. Moreover, the valve manufacturers these days are of mixed quality, with many producing goods under licensed brands. The valves used in our company are primarily for steam isolation, regulation, and drainage. Those most prone to leakage are the valves used for regular boiler discharge, as well as the manual drain valves and automatic drain valves for various high-pressure steam systems. Looking for recommendations: brands of gate valves and globe valves for high temperature and pressure conditions (<10 MPa, temperature ≤ 425 degrees) ； Automatic drain valve brands (same pressure as above) ； Safety valve brands
China Nuclear Su Valve is one such example; I have used its products as well. It’s easy to obtain brand project approvals for them. Among the valves supplied by the vendor, some are genuine while others are fake. Unless we purchase from the original manufacturer, but for our production needs, we use only about 200,000 valves per year, so the original manufacturer has no interest at all.
Our steam trap models from Miyawaki in Japan, such as the TB series with bimetallic temperature control, are primarily used in pipelines. They can handle pressures up to 20 MPA and temperatures up to 550 degrees. They are not affected by the pressure at the upstream end, allowing for free adjustment of the drain temperature. They offer good energy-saving effects, with a service life of 5 to 8 years; they are used in many power plants.

China Nuclear Su Valve belongs to the high-end category and is very expensive. Those of medium quality can contact me. . :)

You get what you pay for; brands like Spyshark are definitely better than cheap domestic products.
