FAQ

What is the difference between a direct-operated and a pilot-operated pressure relief valve like this ZDB 10?

A direct-operated valve uses a spring directly against the poppet to control pressure, making it simple but less stable at high flows. A pilot-operated valve, like the ZDB 10, uses a small pilot valve to control the main stage, allowing for much more stable and accurate pressure control across a wider range of flows and pressures.

How do I correctly set the pressure on the ZDB 10 VP2-41/315V?

To set the pressure, loosen the locking nut on the rotary knob. Turn the knob clockwise to increase the pressure setting and counter-clockwise to decrease it. It is crucial to use a calibrated pressure gauge in the system to verify the setting. Once the desired pressure is achieved, tighten the locking nut to secure the setting.

What does the ‘V’ at the end of the model number signify?

The ‘V’ indicates the seal material used in the valve. In this case, ‘V’ stands for FKM (Fluoroelastomer), commonly known by the brand name Viton. FKM seals are suitable for hydraulic fluids based on mineral oils and offer good resistance to high temperatures.
