Proportional Directional Valve 4WRLE16W8-200LJ-4X/MPT/D24A1 - Bosch Rexroth R901512415

When a cylinder with a large bore has to move fast and still cleanly, available flow decides the outcome. The pilot-operated 4WRLE16W8-200LJ-4X in size 16 supplies 200 l/min nominal flow, passes up to 800 l/min at peak and holds the spool on the ±10 V command value through internal position feedback.

Benefits

• 200 l/min nominal flow and 800 l/min maximum flow move even high displacement cylinders quickly.
• A ±10 V command input connects straight to common controller outputs, so no signal converter is needed.
• Spool symbol W8 in three switching positions gives a defined centre position for axis standstill.
• 350 bar operating pressure at 12.5 kg own weight keeps the power to mass ratio favourable.
• NBR seals are designed for HL hydraulic fluid in ordinary mineral oil service.
• Connection diagram ISO 4401-07-07-0-05 turns a swap against other size 16 valves into simple bolt work.

Application

The focus lies on axes with high oil demand, such as forming presses, lifting gear and large test cylinders. On-board electronics link the valve straight to the machine controller, so no cabinet amplifier is required. CE conformity is declared and supply runs on 24 VDC.
