The Bosch Rexroth 3DR16P4-5X/200Y/00V (R900917772) is a sophisticated pressure reducing valve designed to manage and maintain system pressure within hydraulic circuits. This pilot-operated way pressure reducing valve is integral in ensuring the secondary circuit operates under a specific pressure range. The model features a main valve with a control spool and a pilot control valve that includes an adjustable pressure setting. In its initial open position, the valve allows unrestricted flow from channel P to channel A, while the pressure in channel A is applied to the piston area opposite the compression spring through a bore. The nozzle applies pressure to the spring-loaded side of the control spool, and in conjunction with channel Z, influences ball B in the pilot control valve. The system's operating dynamics are such that when the set value of the compression spring is reached upstream of ball B and in channel Z, it keeps the control spool in an open position. This allows hydraulic fluid to flow from channel P through the control spool to channel A until there's an equilibrium between this pressure and that set on the compression spring, prompting ball B to open. Should external forces cause an increase in pressure within channel A beyond this set value, it results in moving the control spool towards a closed position. This action connects channel A to channel T via a control edge on the spool, allowing excess fluid to be discharged into the tank and preventing further increases in pressure. The design ensures that pilot oil return from the spring chamber is externally directed via port Y, which must always be connected depressurized to the tank. Additionally, there's provision for monitoring reduced pressure in channel A with a pressure gauge connection. This Bosch Rexroth valve supports various adjustment types such as rotary knob or sleeve with hexagon and protective cap options for precise user control. It can be mounted on subplates conforming to ISO standards (which are ordered separately), offering flexibility for integration into different systems. The 3DR16P4-5X/200Y/00V operates at maximum pressures up to bar levels and can handle maximum flow rates measured in liters per minute, making it suitable for high-performance hydraulic applications where precise pressure reduction and maintenance are essential.
