Stainless Steel Flanged Lift Check Valve

Stainless Steel Flanged Lift Check Valve

Product Description

The valve is equipped with a lift check valve mechanism, which allows the fluid to flow in one direction while preventing backflow in the opposite direction. The valve disc is lifted by the fluid pressure when the flow is in the forward direction, allowing the fluid to pass through the valve. When the flow stops or reverses, the valve disc is returned to the closed position by gravity and the spring force.The stainless steel flanged lift check valve is selected to be used in the pipelines of petroleum, chemical and thermal power plants with nominal pressure of pn1.6 ~ 6.4Mpa and working temperature of - 29 ~ 550 ºC. Suitable media are: water, oil, steam, etc.

Features

1. The sealing pairs are matched reasonably. The sealing surface of valve disc and valve seat is made of iron-based alloy or Stellite cobalt based cemented carbide surfacing surface, which has good wear resistance, high temperature resistance, corrosion resistance, scratch resistance and long service life.
2. Various piping flange standards and flange sealing types can be used to meet various engineering needs and user requirements.
3. The valve body has a complete range of materials. The gasket can be selected according to the actual working conditions or user requirements. It can be applied to various pressure, temperature and medium conditions. We can design and manufacture check valves with different structure and connection forms according to user's requirements, which can be used for various equipment.

Application

This type of valve is commonly used in industries such as chemical, petroleum, Natural gas, power generation, and pharmaceuticals, especially in high-pressure, high-temperature, and corrosive media applications, as stainless steel has good corrosion resistance, high-temperature resistance, and excellent mechanical properties, ensuring the valve's long-term use without damage.
