3. Operation

The adjusting screw [14] compresses the
adjusting spring [15], pushes down on the
diaphragm [9], and opens the disc [8] that is
directly connected to it.
The fluid that entered from the primary side
flows out from the upper part of the disk [8] to
the secondary side, and at the same time, acts
directly on the diaphragm [9] as the secondary
side pressure.
When the sluice valve on the secondary side is
closed, the pressure applied to the diaphragm
[9] increases, overcomes the load of the
adjustment spring [15], and the disc [8] closes.
Gradually opening the sluice valve on the
secondary side reduces the pressure applied to
the diaphragm [9] and opens the disc [8].
The fluid flowing out to the secondary side acts
on the diaphragm [9] as the secondary side
pressure, balances with the load of the
adjustment spring [15], adjusts the valve
opening, and keeps the secondary side
pressure constant.
