IMPORTANT
The distance between the edge of the ball body and the insert disc depends on the design.
Lay the large seal (8) between the insert disc (7) and the liquid end
Screw the valve up to the stop.
Cleaning a suction valve:
The suction valve is basically dismantled, cleaned and reassembled in precisely the same way as
the discharge valve.
However, note when assembling the valve seat (2) that it should face the opposite direction. (The
smooth side should point in the direction of flow for all valve seats (2).)
