Proportional Directional Valve 4WRZE32W6-360-7X/6EG24N9TK31/F1D3M - Bosch Rexroth R901009196

Plants that stand still for minutes between two movements unload the main circuit meanwhile, at which point an internally piloted valve loses its ability to respond. The 4WRZE32W6-360-7X receives pilot oil from a source of its own, so it can be set to 360 l/min at 350 bar at any time.

Benefits

• External pilot oil supply keeps the valve controllable even while the main circuit is unloaded.
• 4 to 20 mA current command into on-board electronics, supply 24 VDC.
• 360 l/min nominal flow in size 32, flow up to 1600 l/min.
• Internal pilot oil return, so only one external control line is needed.
• Spool symbol W6, three switching positions, four ports, 43.92 kg.
• 350 bar operating pressure with NBR seals on HL hydraulic fluid, subplate mounting ISO 4401-10-09-0-05 with a 7-pole connector (6 + PE) to EN 175201-804.

Technical data

Application

Test stands for large components, adjustment drives or positioning gear with long dwell times match this layout. The internal return saves a line as long as the tank channel carries no appreciable back pressure. With the concealed auxiliary actuation the axis can be moved without control current.
