XF flexible rubber back-pressure valve is a new-type water supply and drainage valve which has all rubber structure, duck mouth shape and the properties of “forward inflow, reserve flow cut off ”.

Product Introduction:

XF flexible rubber back-pressure valve is a new-type water supply and drainage valve which has all rubber structure, duck mouth shape and the properties of “forward inflow, reserve flow cut off ”. Based on force analysis and stress calculation, according to different conditions, different design mechanism, and choosing different rubber formula, it is made by special technique. When it works forward direction, water flows in with slight water pressure. The bigger the water pressure is, the bigger the valve will be open up and the larger the water flow will be. However, when it works reverse direction, the valve will be physically off and totally-sealed back stop.The greater the pressure is, the tighter the valve shuts and the better the sealing is. It is widely used in various water outlet like municipal engineering, water conservation and sewage treatment. It can avoid back flow and take place of flap valve.

Range of Application:

1. The products performance is outstanding and has a wide range of application.
2. It is suitable for sewage system.
3. It is suitable for draindown system.
4. It is suitable for dam emission.
5. It is suitable for drainage in airplane and highway.
6. It is suitable for sewer disposal.
7. It is suitable for the emission of sewage pool.
8. Smell apart.

Product Feature:

It has obvious advantages compared with traditional flap valve.
1. Open and close automatically, safe and reliable, no noise, no personnel operation and free maintenance.
2. The pressure of the water and operation is small when opens forward direction. The flow can be adjusted according to the water pressure automatically.
3. Cutting off reverse flow and good sealing, no leakage and avoid back flow. The bigger the back pressure is, the better the result is.
4. Anti-corrosion, anti-aging, no deformation, strong adaptability and long service life.
5. Wide size range, nominal diameter from DN50 to DN3000.
