H44 swing check valve
Main purpose
H44 swing check valve is selected for pipelines in various working conditions such as petroleum, chemical, and thermal power plants with nominal pressure PN1.6~6.4MPa and working temperature -29~550 ℃. Applicable media include water, oil, steam, etc.
structure and characteristics
1. The selection of materials is meticulous, in compliance with relevant domestic and international standards, and the overall quality of the materials is high.
2. The sealing pair is advanced and reasonable, and the sealing surface of the valve disc and seat is made of iron-based alloy or Stellite cobalt based hard alloy overlay, 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.
4. Various piping flange standards and flange sealing types can be adopted to meet various engineering needs and user requirements.
5. The valve body material variety is complete, and the gasket can be reasonably selected according to actual working conditions or user requirements, which can be suitable for various pressure, temperature, and medium working conditions.
We can design and manufacture check valves with different structural and connection forms according to user requirements, which can be used in conjunction with various equipment.
