The Bosch Rexroth ZDR6DP2-4X/150-140YM (R900559464) is a high-performance pressure reducing valve designed for precise pressure control in hydraulic systems. This direct operated valve is crafted for sandwich plate mounting and features an integrated pressure limitation function for the secondary circuit, ensuring reliable and consistent performance. The ZDR6DP2-4X/150-140YM is engineered with a robust housing, a responsive control spool, and a durable compression spring to maintain the desired secondary pressure set via its adjustment type. In its default state, Version A of this valve permits free flow of hydraulic fluid from channel A to channel A without restriction while maintaining constant pressure through the balance of forces on the control spool and compression spring. The internal design allows for control signal and pilot oil supply from channel A, with external leakage oil drainage from the spring chamber via a designated bore and channel TY. This model also includes a pressure gauge connection for monitoring secondary pressure directly at the valve. The ZDR6DP2-4X/150-140YM can be equipped with an optional check valve in Version A for free flow return between channels. Versions P and B cater to different requirements: Version P reduces pressure in channel P with an internal pilot supply, while Version B also reduces pressure in channel P but sources pilot oil from channel B. This versatile valve conforms to ISO porting patterns and offers various adjustment types including rotary knobs (with or without scale), sleeves with hexagon and protective cap, or lockable rotary knobs with scale. It's designed to handle pressure reduction tasks in either channel A, B, or P depending on the version chosen. Additionally, this model can come in corrosion-protected designs upon request to ensure longevity even in harsh working environments.
