The Bosch Rexroth DREE20-6X/200YG24K31F1V (R901272515) is a high-performance industrial hydraulic valve designed for reliable pressure reduction in accordance with the command value signal. This valve features a size B, with an electrical connection description of Connector pole PE conforming to DIN EN standards. It is capable of subplate mounting and conforms to CE according to the EMC Directive EU. The DREE20-6X/200YG24K31F1V is equipped with integrated electronics for actuation and has a maximum pressure capacity, with a supply voltage of 24 VDC. The valve has multiple ports and offers a maximum flow rate. Its construction includes FKM seals and it can handle various hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR. This model operates by utilizing a proportional solenoid that sets the pressure in channel A command-value dependently. In its default state without pressure in channel B, the spring holds the main spool in its initial position ensuring that there is no startup jump by keeping the connection from channel B to A closed. The design also includes an optional check valve between channels A and B for free flowback and an optional maximum pressure limitation feature for additional safety against excessive electric control current at the proportional solenoid. The DREE20-6X/200YG24K31F1V valve boasts a linearized pressure-command value characteristic curve and good transient response characteristics making it suitable for various demanding applications requiring precise pressure control.

Size 20, B → A, electrical with integrated electronics, 24 VDC

Industrial hydraulic valve in a high performance range. Reliable reduction of the pressure to the command value signal.

Unpacked Weight: 6.140 kg

Valve for reducing a system pressure Operation by means of a proportional solenoid Proportional solenoid with rotatable and detachable coil For subplate mounting: porting pattern according to ISO 5781 Third way A to Y (Ø 7.5 mm) Linearized pressure/command value characteristic curve Good transient response Optional check valve between A and B Optional maximum pressure limitation With integrated electronics (OBE)

Valves of type DRE(M)E are pilot-operated pressure reducing valves. They are used for operating pressure reduction.

These valves basically consist of a pilot control valve (1) with proportional solenoid (2), a main valve (3) with main spool insert (4), as well as an optional check valve (5). On the proportional solenoid, there is moreover a housing (23) with the control electronics. Supply and command value voltage are applied at the connector (24). At the factory, the command value pressure characteristic curve is adjusted with little manufacturing tolerance.

Type DREE...

The pressure in channel A is set in a command value-dependent form via the proportional solenoid (2).

In rest position – no pressure in channel B –, the spring (17) holds the main spool (4) in its initial position. The connection from channel B to A is closed. A start-up jump is thereby prevented.

The pressure in channel A acts on the surface (7) of the main spool via the bore (6). The pilot oil is taken from channel B and flows through the bore (8) to the constant-current control (9) that keeps the pilot flow constant independent of the pressure drop between channel A and B. From

the constant-current control (9), the pilot flow flows in den spring chamber (10), through the bores (11) and (12) via the valve seat (13) into channel Y (14, 15, 16) and from there to the return flow. The pressure required in channel A is preset at the related amplifier. The proportional solenoid moves the valve poppet (20) in the direction of the valve seat (13) and limits the pressure in the spring chamber (10) to the set value. If the pressure in channel A is lower than the preset command value, the higher pressure in the spring chamber (10) moves the main spool to the right. The connection from B to A is opened. If the set pressure in A is reached, the forces at the main spool are balanced – the main spool is in control position.

Pressure in channel A • Spool face (7) = pressure in spring chamber (10) • Spool face – spring force (17)

If in a standing hydraulic fluid column (e. g. cylinder piston at stop), the pressure in A is to be reduced, (e. g.) a lower command value is preset at the control electronics and in this way a lower pressure is preselected which is present immediately in the spring chamber (10). The higher pressure in A which acts on the surface (7) of the main spool pushes the main spool to the stop against the plug screw (18). The connection A to B is blocked and A to Y is open. The force of the spring (17) now counteracts the hydraulic force acting on the surface (7) of the main spool. In this main spool position, the hydraulic fluid can flow from channel A via the control edge (19) to Y into the return flow.

When the pressure in A has dropped to the pressure in the spring chamber (10) plus ∆p from spring (17), the main spool closes the large control bores in the socket at the control edge A to Y.

The residual pressure differential of approx. 10 bar to the new command value pressure in A is now only unloaded via the fine control bore (21). In this way, a favorable transient response without pressure undershoot is achieved. For the free flow back from channel A to B, a check valve (5) can optionally be installed. Part of this flow from channel A simultaneously flows into the return flow via the open control edge (19) of the main spool A to Y.

Type DREME...

For hydraulic protection against an inadmissibly high electric control current at the proportional solenoid, which imperatively results in excessive pressures in port A, you can optionally install a spring-loaded pressure relief valve as maximum pressure limitation (22). The maximum pressure limitation is pre-set based on the relevant pressure rating (see table).

Integrated electronics (OBE)

Function

The electronics are supplied with voltage via ports A and B. The command value is applied to the differential amplifier ports D and E.Via the characteristic curve generator, the command value solenoid current characteristic curve is adjusted to the valve so that non-linearities in the hydraulic system are compensated and thus, a linear command value pressure characteristic curve is created.The current controller controls the solenoid current independently of the solenoid coil resistance.The power stage of the electronics for controlling the proportional solenoid is a chopper amplifier with a clock frequency of approx. 180 Hz to 400 Hz. The output signal is pulse-width modulated (PWM). For checking the solenoid current, a voltage can be measured at the connector between pin F(+) and pin C(–) which is proportional to the solenoid current. 1 mV corresponds to 1 mA solenoid current.
