Application
Check valves of this type are for use as an independent means
of preventing reverse water flow.
They can also be used for industrial, commercial and similar systems where back pressure, back flow and back syphonage
must be prevented.
The classicfications of appliances to meet these requirements
are specified in EN 1717.
Special Features
• DIN/DVGW-approved
• Universal application
• Easy installation
•Low pressure loss
• Quiet operation
• Create no shock pressure loadings

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).
