MwStop® CHECK VALVE

THE INTELLIGENT BACKFLOW PREVENTION DEVICE UP TO DN1800

Backflow protection

The MwStop® backflow valve reliably protects your building against high water levels, flooding and flooding. The integrated membrane closes e.g. in the event of severe weather events or failure of the pumping station, the pipe leading to the object reliably. This reliably protects your building against flooding caused by backwater.

Odor control

Bad smells from the sewage system are efficiently prevented from penetrating into the building by the MwStop® backflow valve. The innovative membrane also closes the tube when not in use, thereby preventing unpleasant odors. Another positive effect is the optimal protection of the object from pests entering through the sewer system.

Easy installation

Das MwStop® check valve can be easily installed in any common pipe size. Subsequent installation in existing networks is also very easy at any time. As a result, the MwStop® backflow valve can be easily retrofitted not only for new construction projects, but also for existing ones.

Long lifetime

The structure, reduced to an optimum, and the use of high-quality materials of the MwStop® backflow portaction valve are designed to impress with their long service life. The MwStop® check valves are also maintenance-free and an effective add-on for every property.

MwStop® CHECK VALVE

MwStop® check valve can be easy installed within a few minutes in practically all types of pipes. Immediat protection against flood, foreign substances and annoying smells.

The wide range of MwStop® check valves ensures the availability of a suitable model for any kind of application as back-flow protection in sewerage  pipes, rain water pipes or the emerging of odors out of miscellaneous waste water systems or stainless is recommended.

SIZES UP TO DN1800

MwStop® grant efficient protection against water back-flow, flooding and annoying odors.

SCOPE OF APPLICATION

  • main sewer
  • sewers
  • rainwater pipes
  • clarifier basin

MwStop® CHECK VALVE APPLICATIONS

There are numerous causes for back-flow. Heavy rainfall, pipe blockage, operational breakdown of the pumping station, water back-flow from water bodies or other overload of the sewage system might exceed the capacity of the sewage system.

MwStop® check valve protects against water back-flow, intrution of water and foreign substances into buildings as well as into sewage and rainwater pipes. Moreover, MwStop® backflow valve is an effcient protection against inconvenient smells.

BUILDING PROTECTION

  • building protection against flooding
  • water back-flow protection
  • water back-flow protection against underground water

FLOOD PROTECTION

  • public sewer
  • water back-flow protection
  • adjusting of waste water
  • triggering of flush cleaning

ODOR SHUTTER

MwStop® check valve is the perfect solution against molestation of intensive smelling substances from the sewer, due to long periods of drought.

During such times siphons in buildings and facilities that are not used in continuation will dry out and unpleasant odors arise.

HOTEL INDUSTRY, COTTAGES

  • when the siphon dries out after drought periods
  • for irregularly used real estate objects

MwStop® CHECK VALVE FUNCTIONALITY

First Position – SHUT DOWN PHASE – the elastic membrane of the MwStop® backflow valve seals the pipe off tightly until the backlog of the outgoing fl ow reaches the trigger pressure.
Second Position – FLUSHING PHASE – lifts the elastic membrane up and the flush of the backlog water cleans the pipe and removes possible deposits.
Third Position – BACKLOG PHASE – water who pushes the membrane outwards against the wall of the pipe sealing it off effectively against the intrusion of the incoming water. The back-log height varies according to the MwStop® check valve model (maximum 8.000 mm).

CHECK VALVE – VERSIONS

DIFFERENT MwStop® SIZES FOR ALL COMMON PIPE INSIDE DIAMETER

MwStop® backflow valves are available up to 1800. Therefore practically for all pipe dimensions and pipe materials. Special sizes are available on request.

MwStop® CHECK VLAVE MATERIALS

CASING:

The standard casing of the MwStop® consists of stainless steel 1.4404. For sizes up to DN200 and mounting as part of a pipe, PVC/PE can be used as an alternatively offered.

MEMBRANE:

The MwStop® membrane is manufactured up to DN300 in NBR. Larger diameters are made from EPDM.

MwStop® STANDARD FOR GRADIENTS ≥2%

To ensure the full functionality of the  MwStop®  a minimum gradient of 2% is required in the standard version. Under this precondition the EPDM membrane of the MwStop® opens up at a certain water  pressure (water fl ow) and closes if this pressure falls below the normal level. The MwStop® remains closed until the pressure of the backlog water reaches the trigger point. At the trigger point it opens up all of a sudden creating the controlled fl ushing process.

MwStop® SOFT FOR LOW GRADIENT

For installation in pipes with a gradient of less then 2% (minimum 1% is required) the membrane of the MwStop® consists of a more flexible  material. This ensures that even in these situations the flushing process removes the waste water inclusive eventual deposits.
