Proportional Directional Valve 4WRZE16E3-150-7X/6EG24N9TK31/F1M - Bosch Rexroth R900724131

Not every system needs both external pilot lines. This version picks up pilot pressure externally at X but returns pilot oil internally into the T channel, so the Y line is not required. At size 16 the valve meters 150 l/min, commanded by a 4...20 mA current signal and rated to 350 bar operating pressure.

Benefits

• External pilot supply at X holds pilot pressure steady even when the working circuit drops.
• Internal pilot return removes the Y line and cuts piping work.
• 150 l/min nominal flow with a 460 l/min limit.
• Command value 4...20 mA, unaffected by voltage drop on long cables.
• Spool symbol E3 with concealed manual override, weight 12.5 kg.

Applications

The combination suits manifold installations with a short unpressurised tank port and a fluctuating system pressure. Clamping systems and feed axes on machine tools are typical cases. If back pressure in the return line exceeds the permitted value, choose the version with external pilot return instead.
