The Bosch Rexroth ZDR10DA1-5X/210YV/12 (R978910249) is a direct operated pressure reducing valve designed for efficient control of system pressure. This sandwich plate valve is engineered to limit the secondary circuit's pressure by reducing the system pressure. It features a robust housing, a responsive control spool, and a durable compression spring for reliable operation. The secondary pressure can be precisely adjusted to meet specific requirements. This model includes an optional check valve, which allows free flow back from channel A to A in version A. The valve maintains its open position at initial start-up, enabling unrestricted flow from channel A to channel A while simultaneously applying pressure through the control line at the piston area against the compression spring. When the set value is exceeded, the control spool adjusts against the spring to maintain constant pressure levels in channel A. The ZDR10DA1-5X/210YV/12 also features internal supply of control signal and pilot oil via the control line from channel A. Should external forces increase pressure in channel A, the spool will further compress against the spring, connecting channel A with tank channel TB through a control edge on both spool and housing, allowing excess hydraulic fluid to discharge into the tank and preventing further pressure increases. An external leakage oil drain from the spring chamber is always present through channel TA. Additionally, a pressure gauge connection is available for monitoring secondary pressure directly at the valve. For different applications, version P reduces pressure in channel P with internal pilot oil supply from that same channel, while version B reduces pressure in channel P but extracts pilot oil from channel B—necessary if directional valves are used and secondary pressures must not be exceeded. The Bosch Rexroth ZDR10DA1-5X/210YV/12 valve offers versatility with its porting pattern compliant with ISO standards and multiple adjustment types including a rotary knob, sleeve with hexagon and protective cap, lockable rotary knob with scale, and rotary knob with scale. It accommodates various hydraulic requirements with its maximum operating pressures and flow rates specified for each size component series X.
