The Bosch Rexroth DB20-2-4X/315/12W65 (R900568411) is a sophisticated pilot-operated pressure relief valve designed for the effective limitation of operating pressure in hydraulic systems. This valve is specifically engineered to maintain a balance between the hydraulic fluid flow and system pressure, ensuring optimal performance and safety. The DB20 series valve consists of a durable housing and a pilot control valve with various adjustment types to cater to different application needs.
The mechanism of this valve operates by applying pressure to channel P, which affects the main spool. When the set pressure value is exceeded, poppet opens against its spring, allowing hydraulic fluid to flow into the spring chamber and subsequently into the tank—either internally or externally—depending on the version used. This process helps maintain a constant operating pressure by allowing fluid from channel P to flow to channel T.
Equipped with a pressure gauge connection, users can conveniently monitor operating pressures. Additionally, this model offers versatility through its unloading feature and capability to switch to an alternative second pressure rating via port X. Designed for subplate mounting, it adheres to ISO NG 6 and ISO NG 10 porting patterns for secure installation.
The DB20-2-4X/315/12W65 offers various adjustment types for precise pressure customization, including options such as a rotary knob, sleeve with hexagon and protective cap, lockable rotary knob with scale, or a rotary knob with scale. With its maximum operating pressure of 315 bar and maximum flow rate specifications suited for different sizes and component series requirements, this valve is an essential component for hydraulic systems requiring reliable pressure control mechanisms.
