Typical Applications

Check valves of this type are priority suitable for domestic drinking water supply.

The check valve can be used for commercial and industrial applications in consideration of its specifications.

Check valves must be fitted,

•if service pipe, plant and equipment must be protected against back pressure, back flow and back syphonage of non-potable water.

Method of Operation

The check valve protected the service pipe.

Spring loaded check valves have a moving seal disc which is lifted off the seat by a greater or lesser amount depending on the flow rate through the valve. If the flow falls towards zero, then the spring pushes the disc back onto the seat and seals the waterway.

To ensure continuing correct function it is recommended that check valves be regularly checked and maintained (as specified in EN 1717).

•In a drinking water supply the check valves are fitted immediately after the water meter.

o This position ensures optimum protection for the drinking water supply.

•Install in horizontal pipework with test plugs directed downwards.

o This position ensures optimum protection efficiency. o This position is best for testing the valve

• Shut off valves should be fitted on each side of the check valve.

o Shut off valves enables fast testing

•The installation location should be protected against frost and be easily accessible
