Pilot Operated Pressure Relief Valves – Series VBY / VBY*K

Parker's proportional pressure relief valves series VBY*K in size NG06 provide a very low leakage and thus an optimized energy efficiency. The spool type valves work extremely stable and precise.

Markets:
• Industrial
• Machine tools

Features/Benefits:
• Works stable and precise – for high process accuracy
• Low leakage – higher energy efficiency
• 5 pressure stages – enables fine adjustment
• Short delivery time for most versions – no warehousing necessary
• Subplate mounting acc. to ISO 5781
• Main stage spool type valve
• Pilot stage seated type valve
• External drain
• Proportional adjustment

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

Technical Functionality:

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.
