RV280 Controllable anti-pollution check valve EA type with internal thread
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).
