Low Temperature Welded Type DN25mm Stainless Steel Check Valve

Structure description

During the use of this valve, the medium flows in the direction of the arrow shown in the figure.

1. When the medium flows in the prescribed direction, the valve disc is opened by the force of the medium; when the medium is flowing backward, the valve disc is tightly sealed with the valve seat due to the weight of the valve disc and the reverse force of the medium Closed together to achieve the purpose of preventing the medium from flowing back.

2. The sealing surfaces of the valve body and disc are made of stainless steel.

3. The structural length of this valve is in accordance with GB12221-1989, and the flange connection size is in accordance with JB / T79-1994.
