FAQ

What type of hydraulic fluid is compatible with this DV-12-P-B valve?

This valve is compatible with standard hydraulic fluids based on mineral oil (HL, HLP) according to DIN 51524. For use with other fluids, it is crucial to verify the compatibility of the sealing materials.

What is the flow direction for this valve? Is it bidirectional?

This is a throttle valve, and for precise control, flow should follow the direction indicated by the arrow symbol on the valve body. While it may allow flow in the reverse direction, its throttling characteristic is designed for one-way operation.

How do I correctly install and torque the G1/2 inch BSPP fittings for this valve?

For G1/2 inch BSPP (Parallel) threads, it’s essential to use a bonded seal (Dowty washer) or a similar sealing ring. The recommended torque value depends on the fitting material and pressure, but is typically in the range of 45-65 Nm. Always consult the fitting manufacturer’s specifications.
