Proportional Directional Valve 4WRZE16E180-7X/6EG24K31/A1D3M - Bosch Rexroth R901411988

Between sizes 10 and 32 lies a wide field of medium axes. The 4WRZE16E180-7X serves it with 180 l/min nominal flow, operating pressure to 350 bar and a plus or minus 10 V command into on-board electronics.

Benefits

• 180 l/min nominal flow in size 16, range maximum flow reaches 460 l/min.
• Spool symbol E with a blocked centre holds the cylinder in place if the signal fails.
• External pilot oil supply and external return decouple the pilot circuit from a working pressure of up to 350 bar.
• Plus or minus 10 V command into on-board electronics, 24 VDC supply at a 7-pole connector (6 + PE) to EN 175201-804.
• Mounting pattern ISO 4401-07-07-0-05, weight 12.56 kg, NBR seals.

Applications

Valves like this move press rams, lift tables and mould adjustments. At 180 l/min nominal flow a medium cylinder travels briskly yet stays manageable in the fine range. The built-in pressure reducing valve keeps pilot pressure steady.
