Stainless Steel Check Valve DN300 For Industrial
Product Feature
The working characteristics of stainless steel check valves are large load changes, low opening and closing frequency, and long service life once they are closed or open, and no moving parts are required to move. However, once there is a "switching" requirement, it must be flexible, which is more demanding than common mechanical movements. Since check valves are qualitatively determined to be used for rapid closing in most practical uses, and at the moment the check valve is closed, the medium flows in one direction, and as the valve disc closes, the medium quickly drops from the maximum backflow speed to zero, while the pressure rises rapidly, which produces a "water hammer" phenomenon that may have a destructive effect on the pipeline system.

Structural features of the check valve
1. Short structure length, its structure length is only 1/4~1/8 of the traditional flange check valve
2. Small size and light weight, its weight is only 1/4~1/20 of the traditional flange check valve
3. The valve disc closes quickly and the water hammer pressure is small
4. It can be used in horizontal or vertical pipelines and is easy to install
5. The flow channel is unobstructed and the fluid resistance is small
6. Sensitive action and good sealing performance
7. The valve disc has a short stroke and a small closing impact force
8. The overall structure is simple and compact, and the shape is beautiful
9. Long service life and reliable performance
