8.3 Installation instructions
The gate valves are designed for a max. differential pressure equal to the
permissible operating pressure.
If a bypass line is required or requested for other reasons, an ECOLINE GLF 800 globe
valve as per type series booklet 7361.14 is used as bypass valve. The nominal size of
the globe valve depends on the gate valve nominal size (see table).
