Pressure Reducing Valve DREM20-6X/200YG24K4M - Bosch Rexroth R901277145

Many cycles need two pressures, one for infeed and one for holding. The DREM20-6X/200YG24K4M moves between them purely through the electrical command value, works with pressure stage 200 and passes up to 300 l/min.

Benefits

• Pressure change during a running cycle through the command value of the external electronics, with no intervention at the machine.
• Pressure stage 200 in the type code, maximum operating pressure of the valve 315 bar.
• Up to 300 l/min across three ports in two switching positions, acting from B to A.
• Size 25, port pattern ISO 5781, subplate mounting instead of pipe fittings.
• NBR seals, HL hydraulic fluid, 24 VDC through a 3-pole connector (2 + PE).
• 6.1 kg for the assembly.

Applications

Valves of this kind are used in presses and joining equipment that approach at high pressure and hold at a lower one, and in clamping systems with a preliminary and a final force. Because the change is electrical, cycle time does not depend on a mechanical adjustment. Size 25 also covers branches with a larger oil demand.
