FAQ

Question?

What type of hydraulic fluid is this valve compatible with?

Answer:

This valve is typically designed for use with standard hydraulic oils (e.g., HLP, HVLP) according to DIN 51524. However, for specific fluid compatibility, such as synthetic esters or water-glycol fluids, it is crucial to consult the manufacturer’s original specification sheet for this part number.

Question?

Can this valve be used for both A and B ports as check inputs?

Answer:

Based on the port markings, ‘A’ and ‘B’ likely correspond to different circuits within the block. The internal configuration determines the flow direction. Without a hydraulic schematic for part number 405006.001, it is impossible to confirm if it’s a dual check valve or if ports have different functions. It requires verification against the system diagram.

Question?

What are the recommended mounting torque specifications for the connection ports?

Answer:

Torque specifications are critical for high-pressure fittings like these (PN320) to ensure a leak-proof seal without damaging the threads. The exact torque value depends on the fitting type and size. While standard charts exist for DN6 fittings, it is best practice to refer to the Dr-Breit technical documentation or general hydraulic engineering standards for 320 bar systems.
