Introduction:
Rubber duckbill check valve is a new water supply and drainage valve with full rubber structure. It has duck-mouthed appearance and functions of positive flow-in and reverse non-return. It's manufactured according to force analysis and calculation, we use different designing mechanisms and choice different rubber formula to resolve different engineering status. The products used widely in city planning, water conservancy, industry and sewage disposal etc.
Specifications:
1. Provides 100% shut-off, even where debris is present and in large sizes.
(Important for odor control applications).
2. Low cracking pressure. Drainage under low head.
3. Minimal head-loss allows greater flow, saves pumping costs.
4. Head-loss can be customized to meet customer needs.
5. Low installation cost, just slip it on or flange.
6. Maintenance costs reduced.
A. No parts to lubricate or replace.
B. Nothing to freeze or corrode.
C. No structure to come loose.
7. Cannot be propped open.
A. Tamper and vandal proof.
B. Children and animals cannot enter.
C. Backflow prevention assured.
8. Zero operating costs, Zero life-cycle costs.
9. Non-slamming, no noise, no vibration.
10. Absolute backflow prevention saves money.
A. Reduces flood liability.
B. Lowers re-treatment costs.
C. Helps to eliminate compliance violations.
D. Reduces beach erosion.
E. Keeps infrastructure form shutting down (Roads, Airports and Businesses).
F. Eliminates complaints from constituents.
11. Rubber construction and less environmental impact from rust and corrosion.

This valve is our leading product. It is used for draining sewage. In such foreign countries
as Spain or America, it is usually named as duck mouth shaped valve. We are
continuously doing our best to make this valve more practical and more perfect. The
valve can be matched with straight pipeline, flange pipe, cement pipe. At the same time,
they may be widely used on the coast, sea sands, reservoirs, and so on in order to dispose
the sewage or to dredge the floods. Indeed, it is environmentally-friendly valve.
