Date:2018-08-23 / View:81

Rubber drain check valve is also called rubber duckbill valve, rubber check valve, rubber flexible check valve, rubber slow closing reverse valve. The rubber slow stop check valve is a full rubber structure with a ‘duck shaped mouth’ shape, and it is a new type of water supply and drainage valve products with the function of  ‘forward inflow, reverse check’. According to the force analysis and calculation, and in terms of different working conditions, adopting different design mechanism, choosing different rubber formula, and manufacturing according to special technology. When working in a positive direction, water flows through the inlet, and a tiny pressure opens the valve. The larger the water pressure, the greater the opening of the valve, the larger the water flow, the tighter the opening and the sealing. The effect is good. It is widely used in municipal, water conservancy, sewage treatment and other outlet outlets to prevent reverse irrigation, backflow, which  is an ideal product to replace the door.

Characteristics of Rubber discharge check Valve

Compared with the traditional door, the advantages are particularly obvious:

1. Open and close automatically according to water pressure difference, safe and reliable, no noise, no personnel operation, no maintenance.

2. The forward opening water resistance is small, the starting pressure is small, and the flow rate is naturally adjusted according to the water pressure.

3. Reverse seal, no leakage, no backflow, the greater the back pressure, the better the effect.

4. Anti-corrosion, aging resistance, no deformation, strong adaptability, long service lifetime.

5. Wide in size, nominal diameter is DN50 to DN3000.

Application range of rubber drain check valve

1. The product has excellent performance and wide selection.

2. Selected for sewerage system

3. Selected for emission system
