Product specification sheet
Construction
The check valve comprises:
•Housing with flanges
•Housing end casing with flanges
•Test and drain plugs
CERT
Application
Check valves are preferably for use as an independent means of preventing reverse water flow and are for installing directly after a water meter, but also for application in transfer pipes on district water supply systems.
They can also be used for industrial, commercial and similar systems where back pressure, back flow and back syphonage must be prevented.
The types of safety devices required for these purposes are specified in EN 1717.
Special Features
•DIN/DVGW-certified where applicable (for DN40-DN150)
•Universal application
•High temperature resistance
•Create no shock pressure loadings
•Powder coated inside and outside
•Meets KTW regulations for potable water
•Disc, spring and lip seal ring are exchangeable
•Low pressure loss

RV283P Controllabel anti-pollution check valve with flanges
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).
