Technicaldata

6.2.3 Flow direction above the seat

The valve is closed with the medium flow via spring force (control function A, CFA). Because the medium pressure is above the swivel plate, it helps the valve close and also contributes to sealing the valve seat.

The valve opens via pilot pressure.

WARNING!

Risk of injury from pressure surge.

A pressure surge could cause lines and the device to burst. Because of the risk of pressure surge, valves with the flow direction above the seat must not be used for fluid media .

▶ Observe the type of flow and type of medium for operating the device.

In order to ensure complete opening, the minimum pilot pressure must be applied!
