2 3 Type ZDR 10VP5-3X/…YM… Function, section Pressure valves type ZDR 10V are pilot operated pressure valves of sandwich plate design. They are used to reduce a system pressure. The valves consist of the cartridge (1) and a housing (2).The reduced pressure is set via the adjustment element (4). Version VP At rest, the valve is normally open, and fluid can flow unhindered from port P2 to port P1. Pressure in port P1 is simultaneously also present at the main spool (6),via orifice (5),and on the spring loaded inner side of the main spool (6). The pressure is also present via orifice (9) on the pilot poppet (8). When the pressure in port P2 exceeds the pressure level set at the spring (7),then the pilot poppet (8) opens. Pressure fluid then flows from the spring loaded inner side of the main spool (6) via orifice (9), and the pilot poppet (8) into the spring chamber (10) to tank.The main spool (6) moves into the control position and holds the pressure set at spring (7) in port P1 constant.Pilot oil drain from spring chamber (10) is via portTA. Versions VA and VB For versionsVA andVB, the pressure is reduced in portsA2 or B2. In order to allow free reverse flow from portA2 toA1,or B2 to B1 an optional check valve may in included (this is not possible for version VP). An optional pressure gauge connection (3) allow the secondary pressure to be monitored. A P B
