ZDB10VC superposition relief valve

ZDB/Z2DB10V...Type 40 superposition relief valve Orifice (NG) 10 pressure to 31.5MPa flow to 100L/min - Overlay structure - Mounting surface conforms to DIN 24340 Type A and IS04401 - for threaded connection, for base plate mounting - 4 pressure ranges - 6 selectable effective flow directions - With one or two plug-in relief valves -4 adjustment forms knob Adjusting screw with protective cover Lockable knob with scale with scale knob ZDB and Z2DB valves are pilot-operated relief valves with superimposed structure, which are used to limit system pressure. Its composition mainly includes a valve body (7) and one or two cartridge overflow valves. The system pressure is set by the regulating element (4). When the valve is closed in static state, the pressure at port A acts on the spool (1), at the same time, the pressure acts on the spring side of (1) through the orifice (2), and acts on the pilot spool ( through the orifice (3) 6) on.
