Introduction:
Embedded wafer type check valve is used in all kinds of pipelines with working temperature of -196 540 degree to prevent media backflow and pass.
Application:
Through the selection of different materials, can be used with water, steam, oil, nitric acid, strong oxidizing media and urea and other media.
Description:
Structural characteristics of Embedded wafer type check valve
1. Short structure length, its structure length is only 1/8 1/4 of the traditional flange check valve;
2. Small size, light weight, its weight is only 1/20 1/4 of the traditional flange check valve;
3. The valve disc closes quickly, the water hammer pressure is small;
4. Horizontal pipe and vertical pipe can be used, convenient installation;
5. Smooth flow channel, small flow resistance coefficient;
6. Flexible action, good sealing performance;
7. Short stroke of valve disc, small closing impact force;
8. The overall structure is simple and compact, and the shape is beautiful;
9. Long service life and high reliability;
10. Built-in valve stem design, the overall no external leakage point.
