Pressure and temperature reference table

Fengquan·pressure and temperature reference table

The pressure temperature level of the valve is the high working pressure of the Zui expressed by the gauge pressure at the specified temperature. When the temperature rises, the allowable working pressure is reduced. In order to enable the user to correctly select the required valve and avoid losses, according to the relevant provisions of the national GB12224-89 standard, the pressure and temperature rating table of various materials is listed. as follows:

â– Applicable specifications

Our valves are designed and manufactured according to the requirements of advanced standards at home and abroad. The seals are safe and reliable with excellent performance. It is used on various pipelines with working temperature of -40 to 425 (carbon steel) and -40 to 200 °C (stainless steel). This series of valves is used to cut off or connect the medium in the pipeline. It can be applied to water, steam and oil. Nitric acid, strong oxidizing properties and various media such as urea.
