Proportional Directional Valve 4WRTE25E350L-4X/6EG24K31/A1V - Bosch Rexroth R901349958

A cylinder with high volume demand needs a valve that releases a lot of oil and still stays accurate. The 4WRTE25E350L-4X/6EG24K31/A1V provides 350 l/min nominal flow at 350 bar operating pressure and corrects the spool against the ±10 V command through electrical position feedback.

Benefits

• 350 l/min nominal flow and up to 870 l/min maximum flow in size 25.
• Electrical spool position feedback holds the commanded opening even under changing load.
• A ±10 V command value at the on-board electronics, 24 VDC supply.
• Spool symbol E, three switching positions, four ports, ISO 4401-08-08-0-05 mounting pattern.
• FKM seals for higher oil temperatures, 350 bar operating pressure, 17.96 kg valve mass.

Application

Typical places are presses, forging plants and test rigs with large cylinders and short cycle times. The K31 version needs no separate pilot oil lines. At 17.96 kg the valve belongs on a load bearing size 25 subplate.

Manufacturer

Bosch Rexroth lists this valve under material number R901349958. The K31 version routes pilot oil supply and pilot oil drain internally.
