must be prevented.

The classicfications of appliances to meet these requirements
are specified in EN 1717.

RV284 Controllable anti-pollution check valve EA type

RV284...A

Method of Operation

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).
