The Bosch Rexroth ZDRS6VP-1X/50AMG24K32MG (R901025495) is a high-performance industrial hydraulic valve designed for reliable pressure reduction to a predetermined command value signal. This pilot-operated spool valve features a pressure rating of up to 315 bar and is capable of handling maximum flow rates efficiently. It is equipped with a size 6 spool symbol P P and offers electrical actuation with external electronics, including a 24 VDC electrical connector with a 4-pole PE type GOFAVM. The ZDRS6VP-1X/50AMG24K32MG valve is designed for sandwich plate mounting and conforms to the ISO standard connection diagram, as well as the NFPA T3.5.1 R2 D03 Size CETOP D03 porting pattern. The valve's structure comprises a pilot control valve, DC motor with position feedback, and main valve assembly, which can be optionally configured with or without a pressure transducer. This Bosch Rexroth valve functions by setting the reduced pressure in channel A via the DC motor based on the command value. It ensures that the pressure in port A remains consistent with the set pressure at the pilot control valve. Additionally, if there are any instances where the supply voltage fails or an error message is sent by the control electronics, the self-locking DC motor will maintain the pressure adjustment. For applications requiring precise pressure monitoring, this model may include integrated pressure transducers connected to the electronics for recording and monitoring purposes. Alternatively, it can be used with a sandwich plate for external pressure measurement. Overall, this Bosch Rexroth hydraulic valve stands out for its robust construction, precision control capabilities, and versatile application potential in systems requiring controlled pressure reduction with high reliability and safety standards.

PROP PRESSURE CONTROL VALVE -Z ZDRS6VP-1X/50AMG24K32MG

Size 6, P2 → P1, electrical with external electronics, 24 V DC

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

Unpacked Weight: 1.82 kg

Pressure reduction in ports A or P1 with pressure limitation For subplate mounting Porting pattern according to ISO 4401-03-02-0-05 As sandwich plate valve Self-locking DC motor → if the supply voltage fails or an error message is sent by the control electronics, the pressure adjustment is maintained Position feedback Integrated pressure monitoring, optional

Valves of type ZDRS are pilot-operated 3-way pressure reducing valves with pressure limitation of the actuator. They are used for reducing a system pressure.

Set-up

The valves consist of three main assemblies:

Pilot control valve (1) DC motor (2) with position feedback Main valve (3) with main spool (4) Optionally with or without pressure transducer (18)

Function

Command value-dependent setting of the pressure to be reduced in channel A via the DC motor (2). In the depressurized port P, the spring (17) holds the main spool (4) in the initial position → Connection from port A to T open, port P to A blocked Pressure connection from port P to the ring channel (5). Pilot oil flows through the bore (6) via the flow controller (7) into the pilot control chamber (16), via the nozzle (8), the throttle gap (9) into chamber (10) and via bores (11; 12) to port T.

Pressure reduction

Build-up of the pilot pressure in the pilot control chamber (16) as a function of the command value. Movement of the main spool (4) to the right → hydraulic fluid flows from P to A. Actuator pressure present in port A to the spring chamber (15) via channel (13) and nozzle (14). Increase in the pressure in port A to the set command pressure leads to the movement of the main spool (4) to the left in its control position. Pressure in port A is almost identical to the set pressure at the pilot control valve (1).

Pressure limitation not possible if there is dirt.

If the pressure in port A (P1) exceeds the set command pressure, the main spool (4) is moved further to the left. This closes the connection from P to A (P1), opens the connection from P1 to T and limits the pressure present in port A(P1) according to the set command value.

Pressure monitoring

With valves with integrated pressure transducers, the transducer is connected to the electronics and is intended for the recording and monitoring of the pressure set in channel P1. Another alternative is a valve without integrated pressure transducer but with a sandwich plate for pressure measurement. (For example applications, see data sheet 62003)

Notice:

If the voltage supply of the control electronics is switched off or fails, the DC motor stops at its current position which means that, if the hydraulic supply is available, the most recently set pressure is maintained.

Notice:

The valves may not be used for safety-relevant machine functions since only the electrical area and not the hydraulic area is secured. This means that if the hydraulic pressure in P drops to 0 bar, the actuator pressure (A) or secondary pressure (P➀) is inevitably 0 bar as well.

When establishing the electrical connection, the protective earthing conductor (PE) has to be connected properly.
