RV100P
Check valve with flanges
Product specification sheet
Application
RV100P 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 commercial, industrial or similar water
supply systems where back pressure, back flow and back syphonage of water must be prevented.
The classifications of appliances to meet these requirements are
specified in EN 1717.
Special Features
• Universal application
• Creates no shock pressure loadings
• Powder coated inside and outside - Powder used is physiologically and toxicologically safe
• Low pressure loss
• High flow rate
• Operating in any position
Range of Application
Medium Water, medium and light fuel oils, pure ani-
mal and vegetable oils, kerosene, petroleum with less than 15 % aromatic content.
Compressed air
Operating pressure Option A 16 bar

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).

Installation Guidelines
• Installaion in any direction possible
• Install shut off valves
o Isolating valves provide optimal serviceability
• Ensure good access
o Simplifies maintenance and inspection
• For systems with water meters, install right after water meter,
if applicable
o Protects against backflow from water systems

Typical Applications
Check valves of this type are suitable for use as a safety device
on water installations in buildings as specified in EN 1717 and are
also suitable for district water supply mains and for commercial,
industrial and other similar systems.
The following are some typical applications:
• In central water supply systems
• After a water meter
• As a safety device up to liquid category 2 of EN 1717
• Downstream of pumping installations
• Upstream of water heating installations
•In district heating systems
• In agricultaure applications
• In applications with compressed air
