Rexroth Hydraulic Relief Valve DR20-5-5X/200Y With Versatile Connectivity

The Bosch Rexroth DR20-5-5X/200Y (R900597892) is a high-performance industrial hydraulic valve designed for dependable pressure reduction to a set value. This mechanically actuated spool valve is pilot-operated and features a spool symbol B A. It is capable of handling a maximum pressure as specified in its product group ID, and it includes a number of ports for versatile connectivity options.

The valve's type of actuation is mechanical, and it comes in size B A with the capacity for a substantial max flow rate. For installation, the DR20-5-5X/200Y offers subplate mounting with connection diagrams adhering to ISO standards. The weight of the valve is balanced by its robust construction, while NBR seals ensure compatibility with hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, and HFC.

This model of pressure valves operates on a principle where the main valve allows unrestricted flow from channel B to channel A in its rest position. The pilot control valve features an adjustable spring element that helps maintain the desired pressure balance. An external pilot oil return ensures efficient operation.

Additional functionalities include an optional check valve for free return flow from channel A to channel B and a pressure gauge connection for monitoring reduced pressure in channel A. The DR20-5-5X/200Y can be mounted on a subplate or used as a cartridge valve with various adjustment types available such as rotary knobs and lockable rotary knobs with or without scales.

In summary, the Bosch Rexroth DR20-5-5X/200Y (R900597892) represents an advanced solution for controlled pressure reduction in hydraulic systems, offering flexibility in installation and adjustment to meet diverse industrial requirements.
