Proportional Directional Valve 4WRZE16E125-7X/6EG24N9EK31/F1D3M - Bosch Rexroth R901493200

Return filters and long tank lines build counter pressure that upsets the pilot stage of a valve. In the 6EG24N9EK31 version the 4WRZE16E125-7X takes pilot oil internally and drains it through a dedicated Y port, at 125 l/min nominal flow and 350 bar.

Benefits

• Internal pilot supply, external drain - the pilot circuit stays separated from counter pressure in the tank gallery.
• 125 l/min nominal flow at 350 bar, up to 460 l/min in size 16.
• Command value 4 to 20 mA, on-board electronics, 24 VDC.
• Symbol E with concealed auxiliary actuation and a pressure reducing valve in the pilot stage.
• 13 kg, NBR seals, UKCA to SI2016/1091, mounting pattern ISO 4401-07-07-0-05.

Application

Worth choosing in circuits with a return filter, an oil cooler or a long tank line, where tank pressure is not zero. The Y port has to exist in the manifold and reach tank unpressurised. Otherwise the advantage over the purely internal version is lost.
