Product Description

Product introduction

H41H lifting check valve pressure from PN16~PN160,150LB-2500LB, suitable for pressure 1.6~25MPa/2.0-42.0MPa working temperature -29~+550ºC petroleum, chemical, pharmaceutical, fertilizer, power industry and other working conditions of the pipeline, The applicable medium is water, oil, steam, acidic medium and so on. The lifting check valve is selected for the nominal pressure PN1.6 ~ 160MPa/2.0-42.0MPa working temperature -29 ~ 550ºC petroleum, chemical, thermal power station and other working conditions of the pipeline. The applicable medium is: water, oil, steam, etc.

Structure features

1, the selection of materials, in line with domestic and foreign standards, the overall quality of the material is high.
2, the sealing pair is advanced and reasonable, the sealing surface of the valve disc and seat is made of iron base alloy or Stellite cobalt-based cemented carbide surfacing surface, which has good wear resistance, high temperature resistance, corrosion resistance, abrasion resistance and long service life.
3, the product is designed and manufactured according to the national standard GB/T12235. Valve bearing parts using precision casting process casting, beautiful surface quality, no sticky sand, cold insulation and other surface defects; The internal quality is stable, no porosity, sand hole, cracks and other internal defects.
4. Various pipe flange standards and flange sealing types can be used to meet various engineering needs and user requirements.
5, the valve body material variety is complete, the gasket can be reasonably selected according to the actual working conditions or user requirements, and can be applied to a variety of pressure, temperature and media conditions.
Can be designed and manufactured according to user requirements of different structural forms and connection forms of check valves, for various equipment supporting the use.
6, for the pipeline system, its main role is to prevent the media backflow, to prevent the pump and its drive motor machine reversal, as well as the media in the container discharge. The check valve can also be used to supply the pipeline where the pressure may rise to exceed the pressure of the main system.
