Stainless steel lift check valve

stainless steel lift check valve
The check valve is also called the reverse flow valve, the check valve, the back pressure valve, the one-way valve. This type of valve automatically opens and closes by the force generated by the flow of the medium in the pipeline. It is an automatic valve. The check valve is used in the pipeline system. Its main function is to prevent the backflow of the medium, prevent the pump and its driving motor from reversing, and release the medium in the container. Check valves may also be used on lines supplying auxiliary systems where the pressure may rise above the primary system pressure.
Stainless steel lift check valves are selected for use in pipelines under various working conditions such as petrochemical thermal power stations with nominal pressure and working temperature ~℃. Applicable media are water, oil, steam, etc.
2. Structural features Stainless steel lift check valve
The materials are carefully selected and comply with relevant domestic and foreign standards, and the overall quality of the materials is high.
The seal pairs are advanced and reasonable. The sealing surface of the valve disc and seat is made of iron-based alloy or Stellite cobalt-based hard alloy surfacing surface. It has good wear resistance, high temperature resistance, corrosion resistance and scratch resistance, and has a long service life.
Products are manufactured according to national standards/designs.
Various piping flange standards and flange sealing types can be adopted to meet various engineering needs and user requirements.
The valve body has a complete range of materials, and the gaskets can be reasonably selected according to actual working conditions or user requirements, and can be applied to various pressure temperatures and medium working conditions.
Check valves with different structural forms and connection forms can be designed and manufactured according to user requirements for use in various equipment.
