The 4WRLD16E250LJ-4X/MXY/24ND6T brings the spool of symbol E together with a digital axis controller on the housing. The cabinet supplies only 24 VDC plus a +/-10 V command value, from which the valve meters 250 l/min nominal flow at 350 bar operating pressure.

Benefits

• Spool symbol E, 3 switching positions, 4 ports, size 16 body.
• 250 l/min nominal flow, up to 800 l/min maximum flow, 350 bar operating pressure.
• Control loop closed on the valve, the signal path back to the cabinet stays short.
• 24 VDC supply plus +/-10 V command value through a 12-pole connector (11 + PE) to EN 175201-804.
• External pilot oil supply with external pilot oil return, subplate pattern ISO 4401-07-07-0-05.
• NBR seals for hydraulic fluid HL, mass 12.6 kg, UKCA to EMC SI2016/1091.

Applications

The version fits controlled feed axes plus test axes whose controller offers only an analogue output. The short distance between controller with valve improves dynamics compared to an amplifier card in the cabinet. Pilot oil is supplied externally, drained externally.
