Max. Reversed Free Flow L/min

Transcription

1 These Valves are the combination of flow control valve, a deceleration valve and a check valve and used mainly for controlling rapid traverse and feed cycle in machine tools. Switching from rapid traverse to feed is made by a cam operation and fine feed control is accomplished by dial rotation regardless of pressure and oil temperature variation. Rapid return is free of cam actuation. EIC Specifications Model Numbers Max.

In addition, external drain types can also be used in metre-in circuits.

It varies according to the flow rate to be set. For details, please refer to the performance curve.

(This applies only to external drain types) Line filter To carry out flow adjustments by as small degree as L/min or less, be sure to use a line filter, 0µm or less, near the valve inlet. Flow adjustment Loosen locking screw and turn flow adjustment dial clockwise for increase, anti-clockwise for decrease. The dial makes about Four revolutions from zero to full flow and the valve opening indicated on the revolution indicator. fter flow adjustment, tighten locking screw. When Sub-Plates are not used, the mounting surface should have a good machined finish.
