Mode Of Operation - GF NeoFlow Betriebsanleitung

NeoFlow pressure reducing valve
4.3

Mode of operation

P1
The axial movement of the valve piston (4) in the main body (1) results in flow changes in the NeoFlow pressure reducing valve and
thus regulates the existing outlet pressure (P2). The position of the valve piston (4) is regulated by the prevalent pressure of the
control area (5).
Turning the adjusting screw (6) on the pilot valve (3) sets the desired outlet pressure (P2). Depending on the existing outlet pressure
(P2), the media flow in the pilot valve is changed (3). This change of the medium flow results in the adjustment of the pressure in the
control area (5) via the control block (2). To equalize the pressure, the valve piston (4) moves axially in the main body (1).
