The main spool of this pilot-operated valve releases up to 325 l/min, the flow limit being 870 l/min at 350 bar operating pressure. Control runs on a 4...20 mA current command, which arrives without level loss even over long cabling.

Benefits

• 325 l/min nominal flow, 870 l/min flow limit, 350 bar operating pressure
• Input signal 4...20 mA, no level loss over long cable runs
• Internal pilot oil supply, external pilot oil return
• Spool symbol W6, 3 switching positions, concealed manual override for commissioning
• FKM seals for HL fluid, UKCA to SI2016/1091, mass 20.16 kg

Applications

Foundries, forges as well as hot forming lines use such valves because cabinet and machine stand far apart there. Internal pilot pickup saves one line in the manifold. At 325 l/min there is ample reserve up to the 870 l/min flow limit.
