Proportional Directional Valve 4WRZE32E1-520-7X/6EG24ETK31/A1D3M - Bosch Rexroth R900954694

Closing and pressing motions rarely run at constant speed, they start quickly and end damped. The 4WRZE32E1-520-7X/6EG24ETK31/A1D3M converts a voltage command steplessly into a nominal flow of 520 l/min at an operating pressure of up to 350 bar.

Key benefits

• Stepless input over ±10 V - ramps and speed profiles come from the controller, the on-board electronics execute them.
• 520 l/min nominal flow - enough oil for large closing cylinders, with up to 1600 l/min possible by valve size.
• Spool symbol E1 - for a replacement the symbol is the decisive selection criterion next to size 32.
• Internal pilot supply and internal return - the manifold needs no X or Y drilling.
• Interface ISO 4401-10-09-0-05 - subplate mounting on the common size 32 pattern, 4 ports, 3 switching positions.
• 43.6 kg with NBR seals - hydraulic fluid HL, supply 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.

Applications

The valve is installed in die casting machines, forming presses and large hoists where one axis is guided at high flow. Because pilot oil is taken internally, the main circuit has to carry pressure before the pilot stage reacts. Electromagnetic compatibility is documented through UKCA SI2016/1091.
