10.H44X(SFCV) Rubber disc check valve |
|
| |
 |
|
| |
Product introduction: |
|
| |
Rubber disc check valve consists of body,cover and rubber disc.Inside of the rubber disc is steel plate,steel bar and reinforced nylon liner
and the outside is rubber and the disc life is more than one million open-close cycles.The valve is designed with unimpeded bore,so the
pressure loss is very little and no sundries pile up in the body and it is easy to maintain this kind of valve.
The valve is used for feeding system and installed at the outlet of the pump to prevent the fluid flowing backward and water hammering.
Also it can be installed at the inlet ofinlet/outlet's bypass pipe to prevent the water in the cistern flowing backward into the pipe. |

Signal gate valve and signal butterfly valve are used in automatic spraying water pipeline in fire protection system to monitor the water
supplying pipeline and can indicate the valve's opening in a long distance.Rising stem gate valve and opening indicator gate valve are often
used in fire protection system,and if the installation position is high to the ground,rising stem gate valve is used and can show the valve's
opening clearly and if the installation position is low,opening indicator gate valve is used |
