Proportional Directional Valve 4WRTE10W8-50L-4X/6EG24K31/A1M - Bosch Rexroth R900954263

When several axes share one pump, pressure at P swings with the machine cycle. The 4WRTE10W8-50L-4X/6EG24K31/A1M instead uses an external pilot oil feed and an external return while metering a 50 l/min nominal flow.

Advantages

• External pilot oil supply keeps pilot pressure decoupled from the machine cycle.
• External return lets pilot oil flow back free of pressure.
• Nominal flow of 50 l/min, operating pressure up to 350 bar, flow up to 170 l/min.
• Plus/minus 10 V command on the on-board electronics, three switching positions, spool symbol W8.
• Internal spool position feedback for consistent characteristic curves.
• Weight of 9.38 kg, NBR seals, connection diagram ISO 4401-05-05-0-05.

Applications

It is used on plastics and forming machinery whose axes share a single pump. The version equally suits systems with load switching and rapid pressure changes. Ports X and Y are required on the manifold for the pilot stage.
