Key features
1. ŁATWIEJSZA EKSPLOATACJA PRZEPOMPOWNI
Specjalna konstrukcja zaworu umożliwia łatwy dostęp do wnętrza przewodów tłocznych, wirnika lub samej kuli, bez potrzeby demontażu zaworu. Nasi klienci wykonują serwis zaworu o średnicy DN80 w ok. 5 minut. Obsługa pozostałych zaworów trwa od 2 do nawet 4 razy dłużej.
2. MNIEJSZE KOSZTY SERWISU
Plastikowe sztućce, pieluchy czy koszulki – to także spotykane rzeczy w kanalizacji ściekowej, mogące łatwo zatykać zwykłe zawory. Zawór SZUSTERsystem jest w pełni otwarty już przy prędkości przepływu 0,7 m/s co czyni go odpornym na zatykanie. Aby to udowodnić, przeprowadziliśmy test który możesz obejrzeć na naszym kanale na YouTube.
3. OSZCZĘDNOŚĆ MIEJSCA W PRZEPOMPOWNI
Kompaktowe rozwiązanie 2w1 (kolano, zawór zwrotny) lub 3w1 (kolano, zawór zwrotny, zasuwa nożowa) ze zmniejszoną liczbą połączeń kołnierzowych pozwala oszczędzić znaczną ilość miejsca w przepompowni ścieków, a tym samym zmniejszyć koszty budowy inwestycji.
1. QUICK ACCESS TO THE INTERIOR OF THE SYSTEM
The easy-access design allows for quick servicing without dismantling the whole valve. Customers perform the 3” valve service in a average of 5 minutes. Service of other valves lasts up to 4 times longer.

2. PREVENT CLOGGING
Plastic cutlery, diapers and more can often be found in sewage systems. These items can easily clog common valves. This valve’s fully open starting position from the flow rate of 2.3 fps eliminates this issue. We’ve proven the quality of our promise in the video test on YouTube.

3. SPACE-SAVING, LIGHTWEIGHT CONSTRUCTION
With a choice of 2-in-1 (elbow + check valve) or 3-in-1 (elbow + check valve + knife gate), this compact solution saves on cost. Minimum flange connections takes up less space in the lift station, which in turn reduces construction costs.

Technical details
EkoWodrol elbow ball check valves type ESK 01 or COMBI 01 (with threaded connection), and ESK 11 or COMBI 11 (with flange connection) are used for self-actuating protection against reversible wastewater flow from the backflow of the medium the moment the pump/compressor stops working. An additional function of type COMBI is the possibility of manual cutting off at any time the flow of fluid by closing the knife gate valve, which is an integral part of the construction. Elbow check valves are used in wastewater systems with or without the fecal matter up to the the temperature of 104ºF and a pH range of 4-8.
✔ Range of available diameters: 1 1/4″ – 12″.
✔ Pressure rated to 230PSI (tested to 150PSI leak test/230PSI hydrostatic shell test).
✔ Medium temperature: max 104ºF (temporarily to 140ºF).
✔ Flanges complying with ANSI/ASME B16.1 Class 125.
✔ Patents no.: US 8,146,618 B2, US 8,082,949 B2.
✔ API 598 tests and requirements.
✔ Painted with a 200 µm thick coat of epoxy paint.

Elbow ball check valves installation method
Our valve substitutes an elbow on the pipeline and eliminates one flange joint (COMBI check valve eliminates 2 flange connections). It is located at a right angle and connects a vertical pipe with the horizontal one. Please note that the technology of ESK and ESL check valves allows using them on surface and underground installations.
EkoWodrol elbow check valves, type ESK or COMBI can be mounted in horizontal and vertical drainage systems in the positions as shown.
