The Bosch Rexroth S25A50-1X/420J3/12 (R901454193) is a high-performance hydraulic check valve designed for threaded connections, ensuring a leak-free block in one direction. This particular model comes with various cracking pressure options, which can be selected based on the specific application requirements. With a size component series X, this valve is built to withstand a maximum operating pressure of up to 420 bars and can accommodate a maximum flow rate as specified by the order details. The S25A50-1X/420J3/12 valve's robust construction and precise engineering make it suitable for a wide range of hydraulic applications where one-way flow is necessary. Its threaded connection design allows for secure installation into hydraulic systems, minimizing potential leakage points and ensuring reliable performance under high-pressure conditions. The option to choose different cracking pressures adds to the versatility of this valve, making it adaptable to various operational scenarios. Whether used in mobile hydraulics, industrial applications, or heavy machinery, the Bosch Rexroth S25A50-1X/420J3/12 check valve is an essential component that contributes to the efficiency and safety of hydraulic systems. Its capability to prevent reverse flow effectively protects downstream components from damage due to backpressure and enhances overall system integrity.

Important information on hydraulic fluids:

For further information and data on the use of other hydraulic fluids, please refer to the data sheets above or contact us. There may be limitations regarding the technical valve data (temperature, pressure range, life cycle, maintenance intervals, etc.). The ignition temperature of the hydraulic fluid used must be 50 K higher than the maximum surface temperature. Flame-resistant – containing water: Life cycle as compared to operation with mineral oil HL, HLP 30 … 100% Maximum hydraulic fluid temperature 60 °C
1) Small amounts of dissolved zinc may get into the hydraulic system during use.

For applications outside these parameters, please consult us!
