Backwater valve ø 50

Vertical Backwater valve ø 50

Anti-flood devices protect interiors from flooding caused by sewage backflow. Karmat non-return valve ø 50 is an ideal solution where it is impossible to install a non-return valve to protect the whole building e.g. in an apartment block.

The backwater valve ø 50 in version P is fitted in the vertical course of ø 50 sewage pipework attached to the wall by means of brackets.
A backwater valve installed in such a way can protect several facilities at the same time if they are connected to the same sewage system such as a bath or shower base traps.

Backwater valve ø 50 VERSION A for horizontal installation

The backwater valve ø 50 in version A is fitted in the horizontal course of ø 50 sewage pipework attached to the wall by means of brackets.

A non-return valve installed in such a way can protect several facilities at the same time if they are connected to the same sewage system such as a bath or shower base traps.

Backwater valve ø 50 VERSION B for horizontal installation

The backwater valve in version B is connected to the ø 50 pipe socket of an existing pipe fitting in the wall.

A special aesthetic masking rosette allows the valve to be mounted to the wall by means of two screws.

This protects the system from self- detachment in cases of increased pressure in the system caused by sewage backflow.

To the device mounted in a such way, the trap (e.g. a washbasin) is to be connected by means of a special connector with a screw cap.

Backwater valve ø 50 VERSION C for horizontal installation

Backwater valve ø 50 in version C is designed for installation in new or altered sewage systems.

It is mounted to the wall by means of a special ø 50 elbow which is to be connected to the valve with a special nut, that also takes the role of a masking rosette at the same time.

The backwater valve ø 50 in version C is designed for installation in new or renovated buildings.The elbow enables to orient the outflow, at any angle, to the left or to the right and protects the system from self-detachment in the case of increased pressure in the sewage system caused by sewage backflow.

Installation method of ø 50 backawter valves

With the aim to make installation easier, KARMAT produces the ø 50 backwater valve in versions A, B, C as well as in vertical. They are used in all sewage-related systems such as washbasins, sinks, shower bases, dishwashers and washing machines.

Manufactured in different versions making installation possible into any type of system
Designated for installation inside a house or a flat
Aesthetically designed

Method of connecting traps to the valves in version B and C

Trap is easily and tightly connected to the valve by means of a nut and conic gasket.

Proper mounting of the backwater valve in version C

When mounting the elbow to the wall, it is necessary to leave outside 11 to 13,5 mm of screw-thread. Fixing the valve to it, is easy due to a nut and special gasket.

Comfortable manual closure

Backwater valve ø 50 version C

Efficient protection against rodents

Compatible with the standard, the safe distance of the bottom of the casing ensures proper operation and allows for the self-cleaning of the valves
The shape of the chromium-nickel stainless steel guard protects the flap and gasket from damage by rodents and the slipping of the seals during sewage flow.
Smooth and properly shaped internal surface allows free flow of sewage and makes the accumulation of deposits or the blocking up of the valve impossible

All ø 50 backwater valves have a convenient maintenance lever. A small move of the lever blocks the flow quickly and efficiently. This allows to protect premises from unpleasant odours in case of a household sewage system being unused for a longer period of time.

Flap valves

KARMAT Flap valves

Flap valves effectively protect plumbing systems from rats entering the buildings

flap valves and drainage flap valves are made from polypropylene of the highest quality with a supplemented regulator which increases the resistance to sunbeams as well as other atmospheric factors.
a market novelty, it is a specially constructed drainage flap valve wich protects drainage installations against backward flooding and silting do to increasing water levels above the drainage level
the drainage flap valve is installed directly onto the end of a drainage pipe leading to the drainage ditch or a drainage well

Reliable and effective connection

Flap valves and drainage flap valves are made from polypropylene of the highest quality with a supplemented regulator which increases the resistance to sunbeams as well as other atmospheric factors. Polypropylene is harmless to the natural environment, resistant to high temperatures (up to 95°C) as well as aggressive chemical agents present in plant protection products.

A drainage flap valve has a universal connection system consisting of popular Karmat drainage couplers, which enables its installation on drainage pipes or corrugated pipes without holes, from 72 to 100 mm diameter.

All flap valves are equipped with a chromium-nickel cover protecting the flap and gasket. Additionally a chromium-nickel cover A of the lever B has been introduced. They protect against rodents, atmospheric and the environmental conditions (eg. river flow).

Our company uses 100% of the raw material this way, zero post-production waste is created

Example of the assembly of the flap valve and drainage flap valve draining water to a drainage ditch.

Flap valves are mounted by installers onto the ends of sewage pipes draining into collection wells, septic tanks as well as on drainage pipes draining rain water into ditches or rivers.
