• Suitable for general hydraulic applications
• Machine tools, e.g. for clamping and other functions

Technical Functionality:

Series VBY
The valves of the series VBY consist of a pilot with manual adjustment and a spool type main stage. They need to be externally drained. The series VBY can also be used as pressure sequence valve because of the high pressure capability in the outlet port and the external drain port.

Series VBY*K
VBY*K is a proportional pressure relief valve with external drain. Because of the high pressure capability of the outlet port, this valve can also be used as sequence valve. In this case the external drain port Y has to be used. The optimum performance can be achieved in combination with the digital amplifier module PCD00A-400.
