The Bosch Rexroth DRC4-5X/315Y/12 (R901036330) is a sophisticated pilot-operated pressure reducing valve designed for secondary circuit control. This valve is adept at maintaining a consistent reduced pressure level in hydraulic systems, thanks to its main valve with a spool insert and a pilot control valve featuring an adjustable pressure element. Its operation is based on the principle that in the resting state, the valve allows unimpeded flow of hydraulic fluid from channel B to channel A. The main spool is influenced by the pressure in channel A and the spring-loaded side, which also controls the ball in the pilot valve. When there's an equilibrium between the pressure in channel A and the spring setting, the desired reduced pressure is achieved. The valve ensures that any excess pressure beyond the setpoint causes movement towards a closed position, thus preventing overpressure. The DRC4-5X/315Y/12 offers versatility with optional features such as a check valve for free return flow from channel A to B, only available with subplate mounting. It also provides various adjustment types including a rotary knob, sleeve with hexagon and protective cap, lockable rotary knob with scale, and rotary knob with scale for precise control. This model has been designed for ease of monitoring and maintenance with an external pilot oil return via control line into the tank and a pressure gauge connection for checking reduced pressure in channel A. It can be mounted on subplates or threaded connections and accommodates porting patterns according to ISO standards. As an option, it can be utilized as a cartridge valve. The DRC4-5X/315Y/12 stands out for its reliability and precision in controlling hydraulic system pressures across various applications.
