What is the purpose and structural characteristics of the swing check valve?
Swing check valve is suitable for nominal pressure PN1.0MPa~42.0MPa, CLASS150Lb~2500Lb; nominal diameter DN15mm~1200mm, NPS1/2″~48″; working temperature -196C~540C for various pipelines, used for Prevent the media from flowing backwards. By using different materials, it can be applied to a variety of media such as water, steam, oil, nitric acid, strong oxidizing medium and urea.
The structure length is short, and its structure length is only 1/4~1/8 of the traditional flange check valve;
Small in size and light in weight, its weight is only 1/4~1/20 of the traditional flange check valve;
The valve flap is closed quickly and the water hammer pressure is small;
Both horizontal and vertical pipes can be used for easy installation;
Flow to smooth, fluid resistance is small;
Sensitive action and good sealing performance;
The valve flap has a short stroke and a small impact force;
The overall structure is simple and compact, and the shape is beautiful;
Long service life and high reliability
