LYV API 6D Check Valve Feature And Application

1, the structure length is short, its structure length is only 1/4~1/8 of the traditional flange check valve

2, small size, light weight, its weight is only 1/4~1/20 of the traditional flange check valve

3. The valve flap closes quickly and the pressure of the water hammer is small

4, horizontal or vertical pipe can be used, easy to install

5, the flow channel is unobstructed, the fluid resistance is small

6, sensitive action, good sealing performance

7. Short stroke of valve disc and small impact force of closing valve

8, the overall structure, simple and compact, beautiful shape

9, long service life, high reliability
