Regeldrossel 2WFC40S500L-1X/M/K4 - Bosch Rexroth R901451948

A large flow has to be limited proportionally rather than merely switched. The control throttle 2WFC40S500L-1X/M/K4 solves that as a pilot-operated cartridge valve with a nominal flow of 500 l/min at a maximum operating pressure of 420 bar.

Benefits

• 500 l/min nominal flow in size 40 at a maximum of 420 bar.
• Linear flow characteristic held accurate by external piston position feedback.
• Cartridge valve for mounting cavity ISO 7368-BD-10-2-A with two ports.
• Electrical with external electronics, 24 V DC, 3-pole connector (2 + PE) to DIN EN 175301-803.
• NBR seals on hydraulic fluid HL, 7.17 kg weight.

Application

The control throttle sits in the manifold of presses, test rigs and injection moulding machines where speed and force have to be guided. The external electronics take the command value from the machine controller and trim the piston position to match.

Manufacturer
