Proportional Directional Valve 4WRZE10E50-7X/6EG24N9K31/A1V - Bosch Rexroth R978911132

Seal material decides which hydraulic fluid an axis is allowed to see at all. The 4WRZE10E50-7X/6EG24N9K31/A1V is fitted with FKM and works at 50 l/min nominal flow up to 315 bar operating pressure, its pilot oil supplied from outside and relieved to the outside.

Benefits

• FKM seals, rated for HL hydraulic fluid, 8.48 kg weight.
• 50 l/min nominal flow against a maximum flow of 170 l/min in size 10.
• Spool symbol E, 3 switching positions and 4 ports on subplate mounting to ISO 4401-05-05-0-05.
• External pilot oil supply and external pilot oil return separate control pressure from working pressure.
• ±10 V command value on the on-board electronics, 24 VDC on a 7-pole (6 + PE) connector to EN 175201-804.

Applications

Typical installations are found in metallurgy, foundry equipment and forming technology, wherever fire resistant fluids are used. At 50 l/min the control stays finely resolved even on small cylinder areas. Subplate mounting to ISO 4401-05-05-0-05 allows a swap against any existing valve on the same hole pattern.
