The proportional pressure relief valve series RE*E*W has been specially developed for a favourable pressure/flow (p/Q) behaviour and thus enables a improved process and product accuracy. A mechanical maximum pressure stage is optionally available. For sizes NG25, NG32 and NG40 a screw-in cartridge is used, for sizes NG50 and NG63 an additional sandwich unit.
The RE*W model code embraces the pilot valves, covers and cartridges that are also offered as separate items. In combination with the digital power amplifier PCD00A-400 the valve parameters can be saved, changed and duplicated.
Markets:
• Industrial
Benefits:
• Cavity and mounting pattern according to ISO 7368 – for quick, easy integration
• Favourable pressure/flow (p/Q) behaviour – prevents higher pressure variation
• High nominal flow rates up to 4000 l/min – optimum efficiency in relation to valve size
• 4 pressure stages – enables fine adjustment
• 6 sizes, NG16 to NG63 – makes selection easy
• Short delivery time – no warehousing necessary
• Optional mechanical max. pressure stage
Applications:
• Suitable for general hydraulic applications with high flow
• General presses
• Injection molding
