Product Details
Imported flange check valve American
Buhrer brand standard: Refers to the valve that automatically opens and closes the valve flap based on the flow of the medium itself to prevent the medium from flowing backward, also known as check valve, check valve, reverse flow valve, and back pressure valve . It belongs to an automatic valve, and its main function is to prevent the medium from flowing backward, prevent the
pump and the drive motor from reversing, and release the container medium. It can be divided into swing check valve (rotation according to the center of gravity) and lift check valve (moving along the axis).
Size: DN50 ~ 800mm
Pressure rating: ANSI 150 ~ 1500LB
Body material: carbon steel, stainless steel, cast iron
Applicable medium: gas, liquid, steam
Operation method: automatic
Features of imported flange check valve:
1.With built-in swing arm swing-open structure, all opening and closing parts are installed inside the valve body, and do not penetrate the valve body
2. The connecting part of the rocker arm and the valve disc adopts a spherical connection structure, so that the valve disc has a certain degree of freedom in the 360 ° range, and there is a suitable micro-position compensation
3. The sealing surface of the valve sealing pair is welded with alloy steel or cemented carbide, even if it is used in the medium with fine particles, it will not wear away quickly due to erosion.
4. The valve body and bonnet used for higher pressure valves adopt a pressure self-tightening seal structure. The combination of a wedge-shaped seal ring and a four-opening ring, the higher the pressure, the more reliable the seal.
