Proportional Directional Valve 4WRZE10W6-50-7X/6EG24N9EK31/F1V - Bosch Rexroth R900965019

A return line cooler or filter builds up back pressure in the tank leg that the pilot stage should not have to see. The 4WRZE10W6-50-7X/6EG24N9EK31/F1V therefore drains through a dedicated external line, takes its command as 4...20 mA and meters 50 l/min nominal flow at up to 315 bar.

Benefits

• Internal pilot oil supply with external pilot oil return, independent of back pressure in the tank leg.
• 4...20 mA command value, insensitive to cable length and contact resistance.
• 50 l/min nominal flow, maximum flow 170 l/min in size 10.
• Spool symbol W6, operating pressure up to 315 bar, connection diagram ISO 4401-05-05-0-05.
• FKM seals, HL hydraulic fluid, 8.62 kg weight.

Technical data

Applications

The valve works in power units fitted with offline filtration and oil cooling, as found in round the clock installations. A separate pilot drain keeps the null point of the pilot stage steady even when return pressure drifts over the day. At 50 l/min a small cylinder area is enough for even feed motion.
