Product Overview of High-Pressure Swing Check Valve:

The high-pressure swing check valve is a type of valve that can automatically prevent the reverse flow of fluid. The valve disc opens automatically under the pressure of the fluid, and the fluid flows from the inlet side to the outlet side. When the pressure at the inlet side is lower than that at the outlet side, the valve disc automatically closes under the influence of pressure difference and self-weight, to prevent the reverse flow of the fluid. It is suitable for use in various working conditions such as petroleum, metallurgy, chemical industry, thermal power generation, etc., with a pressure range of PN10.0 to 42.0 MPa and a working temperature of ≤ 570℃. It is used as a safety device to prevent the reverse flow of the medium. 

Advantages of the high-pressure swing check valve product:

1. The product is designed and manufactured in accordance with the provisions of NB/T 47044 standard. It has a reasonable structure, excellent performance, and a beautiful appearance.

2. The middle part of the valve adopts a pressure self-tightening sealing structure. The higher the medium pressure, the better the sealing performance.

3. The high-temperature and high-pressure parts are made of heat-resistant alloy steel, which has good high-temperature performance, can withstand high pressure, is durable, safe and reliable.

4. The sealing surfaces of the valve disc and valve seat are made by welding with alloy steel or cobalt-based hard alloy, which is wear-resistant, resistant to high temperature, corrosion-resistant, and has good anti-abrasion performance, and has a long service life.

5. The valve disc rotates around the external pin shaft of the valve seat, reducing the violent impact during closure.

6. The internal pin shaft structure reduces the external leakage points, making it more reliable to use.

Application:

The high-pressure swing check valve is a type of valve that can automatically prevent the reverse flow of fluid. Its valve disc opens automatically under the pressure of the fluid, and the fluid flows from the inlet side to the outlet side. When the pressure at the inlet side is lower than that at the outlet side, the valve disc automatically closes under the influence of pressure difference and self-weight, etc., to prevent the reverse flow of the fluid. It is suitable for use in various working conditions such as petroleum, metallurgy, chemical industry, thermal power generation, etc., with a pressure range of PN10.0 to 42.0 MPa and a working temperature of ≤ 570℃. It is used as a safety device to prevent the reverse flow of the medium.
