890B Jacket insulation regulating valve

Technical Parameters Structure and materials Specification parameter Quality Assurance

890B jacket insulation single-seat control valve,Using the top-oriented unbalanced structure,high strength,Load weight,S-type flow channel,Pressure drop loss is small,Flow coefficient,Adjustable wide range,High accuracy of flow characteristics.
The open flow design, medium tends to open the valve opening direction, good controllability, flow characteristics and small distortion. Special cage for noise reduction and cavitation resistance can be selected according to working conditions. The utility model is mainly used for occasions where the medium is easy to coagulate at room temperature, for example, the medium is paraffin. Steam is injected into the insulating jacket to heat the medium and maintain the flow of the medium.

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 (KOSA) 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. KOSA 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 KOSA 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 KOSA control valve products and design, production and testing according to a higher standard version for customers.
