1.  ERIKS operating companies 

ECON ball check valves are being delivered by several ERIKS operating companies on a 
worldwide basis. In this manual these will be referred to as ‘ERIKS’, the individual terms of 
delivery of the ERIKS operating company having executed the order are applicable. 

 

2.  Product description 

The ECON ball check valves are designed according to the information in our latest catalogue or 
see our websit

www.eriks.com

 and should be used in accordance with the applicable pressure-

temperature rating as stated on this website. ECON ball check valves are provided with casted 
markings according to EN 19. The marking makes the identification of the valve easier and 
contains: 

size (DN) 

pressure rating class  

body material marking 

arrow, indicating the medium flow direction

3.  Requirements for maintenance staff 

The staff assigned to assembly, operating and maintenance tasks should be qualified to carry out 
such jobs and in any circumstance, ensure personal safety  

 

4.  Transport and storage 

Transport and storage should always the valve should be protected against external forces, 
influence and destruction of the painting layer as well. The purpose of the painting layer is to 
protect the valve against rust, during transport and storage. The valves should be stored in an 
unpolluted space and should also be protected against all atmospheric circumstances. There 
should be taken care of the temperature and humidity in the room, in order to prevent condensate 
formation. 

 

5.  Function 

ECON ball check valves are designed for the prevention of flow reversal. The operation of the 
valve is fully automatic allowing liquid to flow in one direction only. The flowing medium presses 
against the ball, thereby push them open. The ball check valve can be installed horizontal and 
vertical (upward flow). 

 
6.  Application 

ECON ball check valves use primarily in water purification stations, sewage treatment 
installations, water supply facilities, pumping stations, etc. Application: for clean, waste and 
sewage water and viscous media. The operation of the valve is fully automatic allowing liquid to 
flow in one direction only. The installation designer is responsible for the check valve selection, 
suitable for the working conditions. The valves are unsuitable, without written permission of an 
ERIKS company, to apply for hazardous media as referred into Regulation (EC) No 1272/2008.
