Description
A controlled flow of 220 l/min lets cylinders start and stop without shocking the plant. The 4WRZ25W9-220-7X/6EG24N9TK4/M uses spool symbol W9 in size 25 for that and handles up to 870 l/min.
Benefits
- 220 l/min nominal flow, flow through the valve up to 870 l/min
- 350 bar maximum operating pressure on interface ISO 4401-08-08-0-05
- Spool symbol W9, three switching positions, four ports in size 25
- Electrical with external electronics, 24 VDC supply, 3-pole (2 + PE) plug
- 20.58 kg, NBR seals, HL hydraulic fluid
Applications
The valve serves presses, lifting gear and injection moulding machines whose axes accelerate and decelerate every cycle. External electronics let ramps and curves live in the machine controller. The ISO 4401-08-08-0-05 hole pattern is standard in size 25.
Manufacturer
