Neutral to aggressive gases and liquids, technical vacuum
6.2
Restrictions
For valves with flow direction above the seat:
Warning!
Risk of injury from pressure surge.
Pressure surges may occur if liquid media flow direction is above the seat. As a result, lines or equipment
may burst and medium may flow out.
▶
Observe the type of flow and type of medium for operating the device.
▶
In the case of flow direction above the seat: to avoid pressure surges, clarify the operating conditions
(medium, line length and line cross-section) with the Bürkert sales office before using liquid media.
