Regeldrossel 2WFC32S320L-1X/M/K4 - Bosch Rexroth R901451944

A command value from the controller is enough to limit flow steplessly, because piston position is fed back externally and corrected. Nominal flow is 320 l/min and the characteristic runs linear. As a cartridge valve it sits in a mounting cavity to ISO 7368-BC-09-2-A and is released to 420 bar.

Benefits

• Nominal flow of 320 l/min with a linear flow characteristic
• External piston position feedback for control accuracy
• Maximum operating pressure of 420 bar in size 32
• Cartridge valve to ISO 7368-BC-09-2-A, no subplate required
• Electrical with external electronics, 24 VDC, 3-pole connector (2 + PE) to EN 175301-803
• Mass 4.54 kg, NBR seals for HL hydraulic fluid

Application

Valves of this kind belong in the control blocks of large presses, injection moulding machines and test rigs where speeds are driven rather than switched. Sitting inside the block, the valve avoids long line runs and the pressure losses that come with them. The external electronics are ordered separately and close the control loop.

Manufacturer

Bosch Rexroth lists this proportional cartridge valve 2WFC32S320L-1X/M/K4 under material number R901451944. Data sheets RE 29403 and RE 07600-B carry the characteristic curves, the installation dimensions and the interface data. The mounting cavity has to match ISO 7368-BC-09-2-A or the cartridge will not fit.
