6.2.3 flow direction above seat
The valve is closed by spring force (control function A, CFA) with
the medium flow. As the medium pressure is over the swivel plate, it
supports the closing process of the valve and also contributes to the
sealing of the valve seat. The valve is opened by the pilot pressure.
Warning!
risk of injury from water hammer!
A water hammer could crack the lines and device. Due to the risk of
water hammer, valves with a flow direction above seat must not
be used for liquid media.
▶ Consider the type of flow direction and the type of medium for
operation of the device.
To ensure complete opening, the minimum pilot pressure
must be applied.
