Description:

Rexroth Overflow Valve DZ20-2-52 200 is a pilot operated sequence valve manufactured by Bosch Rexroth. This valve is suitable for hydraulic systems with pressure-controlled sequential operation and consists of a pilot valve, a main valve with inserted main spool and an optional check valve. Relief valve is a kind of hydraulic control valve, mainly used to control the pressure in the hydraulic system, when the system pressure exceeds the set value, the relief valve will automatically open, the excess hydraulic oil will flow back to the tank, in order to protect the system from the damage of excessive pressure.

Areas of application:

The Rexroth Overflow Valve DZ20-2-52 200 is mainly used in hydraulic systems for pressure-controlled sequential operation. It can be used in a wide range of hydraulic systems such as machine tools, hydraulic test equipment, hydraulic transmissions, etc. for precise pressure control and sequential operation. Hydraulic system: In various hydraulic equipment, such as hydraulic presses, injection molding machines, die-casting machines, etc., it is used to control the pressure of the hydraulic system and prevent the system pressure from being too high. Industrial automation: in automated production lines, by controlling the pressure of the hydraulic system, to achieve precise control of various industrial equipment. Mechanical engineering: in engineering machinery, such as excavators, loaders, etc., the relief valve is used to control the working pressure of the hydraulic system to protect the system from damage caused by excessive pressure.

Advantages:

Precise control: DZ pilot operated sequence valve can precisely control the pressure sequence action in the hydraulic system to ensure stable operation of the system.
Compact structure: The valve has a compact structure, which is easy to install and maintain.
High working pressure: Maximum working pressure up to 315 bar, suitable for high pressure hydraulic systems.
High flow rate: The maximum flow rate is up to 600 L/min, which meets the demand of high flow rate.
Various adjustment elements: 4 types of adjustment elements are available, including knob, hexagonal socket with guard, graduated knob with lock and non-locked graduated knob to suit different applications.
Various pressure levels: 4 pressure levels (50,100,200,315 bar) are available, allowing the selection of the appropriate pressure level according to system requirements.
Various ways of controlling oil supply: No code for internal supply and internal discharge, X=external supply and internal discharge, Y for internal supply and external discharge, XY=external supply and external discharge, with check valve serial number: No with number with check valve, M without.
