815d low temperature liquid nitrogen special regulating valve is widely used in the automatic control of industrial production processes such as petroleum, chemical industry, metallurgy, etc. It is especially suitable for the regulation of medium (such as liquid oxygen, liquid nitrogen, etc.) at low temperature from - 60 ℃ to - 196 ℃. It is one of the regulating valve products specially developed by our company for ultra-low temperature working condition. It is different from the normal temperature control valve in that the long neck type upper valve cover is used to make the packing work at normal temperature.

Control valve selection
The selection of control valves in industrial control valve selection process is particularly important, due to the various working parameters in different, choose to meet the technological requirements and the best cost control valves need experienced technical staff. Refined Europe (GEROYAL) company based on years of control valve selection calculation experience, independently developed "control valve selection software" can effectively improve the control valve selection efficiency and accuracy. GEROYAL software control valve selection, a code generation control valve comprehensive performance parameters, such as control valves, control valve specifications, calculation of control valve selection scheme comparison for the comprehensive technical documentation requirements of working condition.
case analysis
Control valve product coverage, some special cases often appear in complex condition, we GEROYAL company technical department can provide case control valve structure, materials and accessories such as a full range of your analysis report.
Provide higher implementation standards
As one of the pressure control valve pressure piping components shall be in strict accordance with relevant industry standards in design, production and testing, in strict accordance with relevant industry standards GEROYAL control valve products and design, production and testing according to a higher standard version for customers.
