Scope of application

SSDF water bottom valve has reasonable design, advanced manufacturing technology, simple installation, convenient use and maintenance, and has the advantages of low friction resistance, long service life, and energy saving of 5-7%. It is a replacement product of the underwater foot valve. A foot valve is installed for each pump. The foot valve is usually installed below the water surface, while the water-type foot valve is installed above the water surface. Widely used in petroleum, foundry, textile, printing and dyeing, metallurgy, mining, drainage and irrigation industries.

Structural features

  1. When used as a bottom valve, it can replace the underwater bottom valve, and it can be installed at the 90-degree turn of the horizontal pipe and the water inlet riser above the water surface.
  2. When used as a check valve, it can be installed on a 90-degree conversion head, which can replace the elbow and take up less space. It also has a non-returning effect, its unique sealing performance, the non-returning effect can be achieved without leaking water, and there is no damping device, which has a certain mitigating effect on the damage of water hammer.
  3. The energy-saving effect is significant. It can save energy by about 5-7% during normal work (based on kiloton / meter power consumption), reduce water supply operation costs. After half a year of use, the saved electricity costs can recover the investment cost of the valve you purchased. Its energy saving effect cannot be achieved by the foot valve.
  4. All connection methods of this product comply with international regulations and have good ventilation performance.
