Rubber Flap Swing Check Valve German Stand Ductile Iron GGG50 PN10/16 DN50-DN600(SFCV)For Water Gas Oil

product description

1. The rubber flap check valve has a small working distance and a short opening and closing streamer.

2. The rubber flap check valve has good sealing performance, small friction between the sealing surfaces and long service life.

3. The rubber flap check valve has a simple structure and is more convenient to build and maintain.

In the long river of opening and closing, the rubber disc check valve is anti-wear due to the fact that the friction between the disc and the sealing surface of the valve body is smaller than that of the gate valve; the opening height seems to be 1/4 of the diameter of the valve seat. The gate valve is much smaller; usually there is only one sealing surface on the valve body and the valve disc, so the construction process is better and maintenance is better; since the packing is a mixture of asbestos and graphite, the temperature resistance level is higher.

Once the disc of the rubber disc check valve is moved away from the closing whistle, there will be no more triggering between its valve seat and the sealing surface of the disc, so that its sealing surface is damaged very little, so its sealing habit is very good. OK, the downside is that particles in the cross-flow media may be trapped between the sealing faces. However, if a valve disc is made of steel balls or porcelain balls, this theme will be solved. Because the valve seat and valve disc of most globe valves are relatively easy to repair or replace, at the same time, when repairing or replacing the sealing prefabricated components, it is not necessary to disassemble the inner and outer valves from the pipeline, which is welded into a ring when the valve and the pipeline are welded. The yard that buckles one ring is very applicable.
