Ball check valves ENG – EkoWodrol Innowacje

EkoWodrol ball check - first with fully open position and a constant K factor starting from the flow rate of 0.7 m/s

Patented EkoWodrol ball check valves, due to the unique characteristics and usable features, are widely used in ordinary lift stations and pumping stations with separation of solids and pumps. Thanks to safety and ease of use (the possibility of placing the cover in service position), they are also valued by Users of sewer systems.

TYPE ESK: Ball check valve + Elbow
TYPE COMBI: Ball check valve + Elbow + Knife gate
TYPE ESL: In-line ball check valve

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 DN80 valve service in a average of 5 minutes. Service of other valves lasts up to 4 times longer.

1. QUICK ACCESS TO THE INTERIOR OF THE SYSTEM

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 0,7 m/s eliminates this issue. We’ve proven the quality of our promise in the video test on YouTube.

2. PREVENT CLOGGING

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 (except ESK 11.L – when the pump/compressor starts 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 40ºC and a pH range of 4-8.

✔ Range of available diameters: DN32 – DN300.

✔ Pressure rated to PN 1.6 MPa (all valves are tested to PN 1.0 MPa leak test / PN 1.6 MPa hydrostatic shell test).

✔ Medium temperature: max 40ºC (temporarily to 60ºC)

✔ Painted with a 200 μm thick coat of epoxy paint, RAL 5005 (optional: 300 μm, other colours).

✔ Flanges complying with EN 1092-2.

✔ EN 12050-4 tests and requirements.

EkoWodrol elbow check valves are made from cast iron (DN32 – DN150) or ductile iron (DN200 – DN300). Their optimal ranges of working pressure are adapted to the pressure occurring in the sewage systems.

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.
