870G Small caliber high pressure regulating valve

Technical Parameters Structure and materials Specification parameter Quality Assurance

Our 880L ultra small flow needle valve is a kind of top guide single seat valve, it has a simple structure, good sealing performance, reliable use and so on. The top guide system is effective enough to overcome the small opening shock, effective and long service life. A smaller flow coefficient is chosen to increase the use of the valve. Multi spring pneumatic film mechanism or electric actuator can be selected..
The valve is the use of KOSA technology, professional development of a small flow of the operating conditions of a product. The body is small in size and light in weight, and the inner screw thread structure is more convenient to be installed and disassembled. The whole body has the characteristics of small size, light weight, high performance and precise control of micro flow. Does not apply to the medium of the more dirty occasions, adjusting the media containing granular media, should be aimed at the problem of small throttle clearance, pay attention to prevent the occurrence of blocking card phenomenon. Especially suitable for liquid, steam and other media in the mainstream of the regulation.

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.
