No. The "/315" indicates this valve is equipped with a specific spring for the 315 bar pressure stage. Although the valve body is rated for 630 bar, the spring in this model is designed for reliable adjustment only up to 315 bar. Attempting to set it to 400 bar will result in inaccurate pressure control and potential spring damage. For higher pressures, select a model with a /400 or /630 spring code.
This is an NG10 size cartridge. You must use a standard DBD NG10 threaded cavity (commonly M35 ×1.5 or M33 ×1.5, but always verify with the official dimensional drawing for your specific series). The recommended tightening torque is typically 80 -100 Nm, but you should confirm this in the technical data sheet to avoid damaging the threads or seals.
Backpressure is fully additive. Any pressure at the T-port directly adds to the pressure required to open the valve. For example, if the valve is set to 300 bar and the T-port has 20 bar of backpressure, the system will relieve at 320 bar. Ensure the total pressure (set pressure + T-port backpressure) does not exceed the valve's maximum rating of 630 bar.
Common causes for chatter in direct-acting relief valves include:
No. The standard R900424150 with NBR seals is not compatible with phosphate ester (HFD) fluids. For HFD applications, you must order a variant with FKM (Viton ®) seals, which are typically denoted by a /V suffix in the model code (e.g., DBDS10K1X/315V).
