H41H/Y lifting check valve

Working principle and purpose of the product:

The H41H/Y lift check valve is selected for pipelines with a nominal pressure of PN1.6~6.4MPa and a working temperature of -29~550 ℃ in various operating conditions such as petroleum, chemical, and thermal power plants. Applicable media include water, oil, steam, etc. It is one of the important links in the production process regulation system, which is a valve that controls the unidirectional flow direction of the medium in the pipeline and prevents the medium from flowing back.

Product structure characteristics:

1. The H41H/Y type lifting check valve has the advantages of reliable operation, simple structure, and convenient maintenance, and is applied in production processes such as metallurgy, light textile, chemical industry, purification equipment, power, and petroleum.

2. When the medium flows into the valve body as indicated by the arrow on the valve body, the pressure of the medium exerts an upward thrust on the valve disc. When the medium thrust exceeds the gravity of the valve disc, the valve opens. When the force exerted by the pressure of the medium behind the valve on the valve disc plus the gravity of the valve disc itself is greater than the force exerted by the pressure before the valve on the valve disc, the valve closes to prevent the medium from flowing back.

3. The selection of materials is meticulous, meeting relevant domestic and international standards, and the overall quality of the materials is high. 　　

4. The sealing pair is advanced and reasonable, and the sealing surfaces of the valve disc and valve seat are made of iron based alloy or Stellite cobalt based hard alloy surfacing. It has good wear resistance, high temperature resistance, corrosion resistance, scratch resistance, and long service life. 　　

5. The product is designed and manufactured according to the standard GB/T12235. 　　

6. Various piping flange standards and flange sealing types can be used to meet various engineering needs and user requirements. 　　

7. 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, for use with various equipment.
