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.

Technical data

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.
