The Bosch Rexroth DB20-2-5X/330YE (R900784525) is a sophisticated pressure relief valve designed for precise control of operating pressure in hydraulic systems. This pilot-operated valve is engineered to serve as a safety device that limits the system pressure to a predetermined level. The DB20-2-5X/330YE consists of a main valve with a spool insert and a pilot control valve featuring an adjustable pressure element, ensuring reliable and responsive operation. The functionality of this valve is based on the balance of pressure applied to the main spool against the force of an adjustable spring in the pilot control valve. When system pressure exceeds the set value, it triggers the ball in the pilot control to open, allowing hydraulic fluid to flow from the spring-loaded side of the main spool into the tank, either internally or externally depending on the type. This action maintains system pressure at safe levels by connecting channel P to T when necessary. Additionally, this model allows for unloading or switching to an alternative pressure rating via port X, providing versatility in application use. It is designed for subplate mounting with porting patterns conforming to ISO standards NG6, NG10, and NG16, and can also be used as a screw-in cartridge valve for threaded connections. The DB20-2-5X/330YE offers various adjustment types for setting pressure including options such as a rotary knob, sleeve with hexagon and protective cap, lockable rotary knob with scale, or rotary knob with scale. This Bosch Rexroth relief valve is not only functional but also durable due to its corrosion-protected design. It meets stringent quality standards and is suitable for use in various hydraulic applications where precise pressure control is essential for both performance and safety.
