Proportional Directional Valve 4WRZE32W9-360-7X/6EG24TK31/A1M - Bosch Rexroth R900976785

Built without an integrated pressure reducing valve, this unit expects the plant to hold pilot pressure in range, and in exchange delivers 360 l/min nominal flow with spool symbol W9.

Key benefits

• No pressure reducing valve in the pilot stage, the plant supplies pilot pressure itself and the internal stage is saved.
• Spool symbol W9 in 3 switching positions on 4 ports, interface ISO 4401-10-09-0-05.
• 360 l/min nominal flow at a maximum of 1600 l/min and 350 bar operating pressure.
• External pilot oil supply, internal pilot oil return, matched to plants running their own pilot pressure circuit.
• 43.1 kg, ±10 V command value on 24 VDC, NBR seals for HL hydraulic fluid.

Applications

The variant belongs in plants where pilot pressure is already regulated, for example large press installations with a dedicated pilot pressure station. Users have to keep pilot pressure inside the range released by the manufacturer, because the valve does not limit it internally. Electrical hookup is a 7-pole connector (6 + PE) to EN 175201-804.
