The Bosch Rexroth DR30-5-5X/350YM/12 (R978878211) is a precision-engineered pressure reducing valve designed for effective hydraulic flow regulation. This valve is part of the DR series, known for their pilot-operated control from the secondary circuit, ensuring reliable and consistent performance. The main valve comprises a main spool insert and a pilot control valve featuring a pressure adjustment element. It operates on a basic principle where, in its rest position, it allows unrestricted hydraulic fluid flow from channel B to A. The pressure in channel A is balanced against a set value by the spring tension, which when exceeded, prompts the ball to open and adjust the main spool towards a closed position. The DR30-5-5X/350YM/12 valve achieves the desired reduced pressure when there's equilibrium between channel A's pressure and the spring setting. An external pilot oil return ensures efficient operation by directing fluid back into the tank via a control line. This model also offers an optional check valve for free return flow from channel A to B when subplate mounted. For monitoring purposes, it includes a pressure gauge connection that allows checks on the reduced pressure in channel A. Designed for versatility, this Bosch Rexroth valve can be mounted on subplates with porting patterns according to ISO standards or used as a threaded connection or cartridge valve. Users can choose from various adjustment types such as rotary knobs (with or without scales), sleeves with hexagon and protective cap, or lockable rotary knobs with scale. With its size tailored to component series X specifications, it can withstand maximum operating pressures up to 350 bar and facilitate maximum flow rates as indicated by its model code. The DR30-5-5X/350YM/12 is ideal for applications requiring precise pressure regulation within hydraulic systems while maintaining efficiency and reliability in operation.
