ZDB16VP2-30/20 is a hydraulic pressure control valve, it is belong to Pressure Control Valve.
'Z' :generally reprents the series or instruction stype of Superimposed;
'DB':indicates that it is pilot overflow valve;
'16' :generally the NG is 16, NG decided that flow capacity and flow rate of hydraulic oil inside valve.
'VP' : it controls the type of oil, flow from P exit to A exit, it states that the direction and method of controlling the oil circuit.
'2' indicates that an adjusting bolt with a protective cover, which is related to the characteristics of the pilot relief valve adjustment mechanism. Automation production line: in various fluid power systems of automatad production lines, the one-way valve can control the flow direction of the fluid , ensure that the actuators of each station move in sequence, and improve the automation level and operational reliability of the production line. For example, it is used in hydraulic drive system in material handling, assembly and other stations.
'30' indicates that the serial No.
'20' means that set pressure is 2.0 Mpa, this data is used to limit system pressure, is a tipical performance parameter of overflow valve.

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 the spool (1) through the orifice (2), and acts on the pilot valve through the orifice (3). on the core (6). If the pressure of A rises and exceeds the fixed value of the spring (5), the pilot (6) overcomes the spring force and opens, and the oil can enter T from the spring side of the spool (1) and throttling (3), and the resulting pressure drop makes Valve (1) moves accordingly, which connects ports A and T, while spring (5) sets the pressure constant. The control oil returns to the outside from the two spring chambers through the oil port T.
The pressure measuring port (8) can detect the pressure.
Attention: the pilot-operated structure relief valve has internal leakage, if it is used as a safety valve that requires a small internal leakage, ZDBD type superimposed relief valve (direct-acting structure) can be selected.
