Proportional Directional Valve 4WRPDH6C4B24L-2X/M/24ND6T - Bosch Rexroth R901461168

When thin walled parts are clamped, the rate of pressure build-up decides whether the part keeps its dimensions. The 4WRPDH6C4B24L-2X/M/24ND6T follows the command signal with up to 24 l/min at an operating pressure of 350 bar and corrects the spool through its internal feedback.

Benefits

• Metered pressure build-up at the clamping cylinder, 24 l/min rated flow at 350 bar.
• Spool symbol C4 with four switching positions and four ports.
• On-board electronics, command value 10 VDC bipolar or 4 ... 20 mA, 24 VDC supply.
• ISO 4401-03-02-0-05 port pattern in size 6, installed mass 3.44 kg.
• NBR seals for HL fluid, UKCA marked to SI2016/1091.

Application

Fixtures in tool and mould making, clamping systems on machining centres and joining stations use this control to separate force from travel. The 12-pole plug (11 + PE) carries command signal, supply and diagnostics. The same job with spool symbol C3 is covered by a separate material number.
