What is a single door check valve?
The single door check valve, also known as the single plate check valve, is a common type of check valve. The main function of the single door check valve is to prevent the backflow of the medium when the direction of flow changes and ensure the normal operation of the pipeline system and equipment.
The single door check valves have a solid thermoplastic body and a very thin “disc” profile, making them ideal for valve applications requiring short nozzle lengths. This check valve combines several excellent characteristics to make it different from the traditional check valve, perfectly realizing the silent, fast, and non-attack operations. The most prominent of these are the high precision machining of the clapper and the quick operation of the closing action.
Advantages of single door check valve
1. Prevent fluid backflow
The main function of the single door check valve is to prevent media backflow and protect the normal operation of pipeline equipment.
2. Low-pressure drop
Compared to other types of check valves, single door check valves have much less pressure drop and valve closing impact and do not affect the pipeline flow.
3. Stable operation
During the operation of the single door check valve, the discs are closed quickly, the water hammer pressure is small, and the phenomenon of water hammer will not occur. It can ensure the stability of pipeline operation, long service life.
4. Easy to install and maintain
The overall structure of the single door check valve is simple and small, which is easy to install and maintain.
5. Wide range of application
Single door check valve is suitable for pipeline systems of various media, such as water, oil, gas, etc.
6. Convenient maintenance
Single door check valves are easy to remove and maintain. You only need to unscrew the nut and remove the valve for maintenance and replacement.
7. Small volume and light weight
Single door check valve has a short structure length, and its structure length is only 1/4 ~ 1/8 of the traditional flanged check valve.
Its weight is only 1/4 ~ 1/20 of the traditional flanged check valve.
