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).
