H41H\W Lift Check Valve
1. Main purpose of H41H\W lift check valve
The lift check valve is selected for the pipelines of various working conditions such as petroleum, chemical industry, thermal power station, etc. with a nominal pressure of PN1.6 ~ 6.4MPa and a working temperature of -29 ~ 550℃. Applicable media are: water, oil, steam, etc.
2. Structure and characteristics of H41H\W lift check valve
1. The selection of materials is exquisite, in line with relevant domestic and foreign standards, and the overall quality of the materials is high.
2. The matching of sealing pairs is reasonable. The sealing surface of the valve disc and valve seat is made of iron-based alloy or Slite cobalt-based hard alloy surfacing surface, which has good wear resistance, high temperature resistance, corrosion resistance and scratch resistance. ,long lasting.
3. The products are designed and manufactured according to the national standard GB/T12235.
4. Various piping flange standards and flange sealing types can be used to meet various engineering needs and user requirements.
5. The material of the valve body is complete, and the gasket can be reasonably selected according to the actual working conditions or user requirements, and can be suitable for various pressure, temperature and medium working conditions.
Check valves with different structural forms and connection forms can be designed and manufactured according to user requirements, which can be used as supporting sets for various equipment.
