Proportional Directional Valve 4WRTE10E1-100L-4X/6EG24TK31/A1M - Bosch Rexroth R900756742

Some systems have a regulated pilot pressure supply but no second tank port on the manifold. That is what the 4WRTE10E1-100L-4X/6EG24TK31/A1M targets, with an external pilot feed and an internal return at a 100 l/min nominal flow.

Advantages

• External pilot feed through X, pilot pressure comes from a regulated source.
• Internal return, so a separate Y port on the manifold is no longer needed.
• Nominal flow of 100 l/min, up to 170 l/min total, operating pressure up to 350 bar.
• Plus/minus 10 V command on the on-board electronics, spool symbol E1.
• Internal spool position feedback, three switching positions on four ports.
• Weight of 9.54 kg, NBR seals, 24 VDC supply voltage.

Applications

The version is intended for manifolds with their own pilot pressure line and a short unpressurised tank path. It saves one fitting compared with the fully externally piloted variant. Back pressure in the tank line has to be limited when the return is internal.
