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 cycles 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. Specifications UCFG---- - UCFG---- - UCFG---C- - UCFG--8-- - UCFG--8-- - UCFG--8-C- - UCFG--- - UCFG--8- - UCFG--- - UCFG--8- - UCFG--- UCFG--- Max.

Line filter To carry out flow adjustments by as small degree as L/min (.5 U. S. GPM) or less, be sure to use a line filter, µm or less, near the valve inlet. D Minimum required pressure difference The minimum pressure differential between inlet and outlet port is required to obtain the optimum pressure compensation. It varies accordingly to the flow rate to be set. For details, refer to the performance curve. Spool push down level Limit the spool push down level within the allowable maximum stroke range shown in the installation drawings. llowable drain port back pressure Limit to. MPa (5 PSI). In addition, connect the drain pipe independently and directly to the tank. (This applies only to external drain types.) Flow adjustment [UCFG-, UCF G-] Loosen the locking screw and turn the flow adjustment dial clockwise for increase, and anti-clockwise for decrease. The dial makes about four revolutions from zero to full flow and the valve opening is indicated on the revolution indicator. fter flow adjustment, tighten the locking screw. [UCF G-] Loosen the locking screw and turn the flow adjustment handle clockwise to increase, and anti-clockwise to decrease. Open condition is indicated in digital-scale in built-in revolution indicator. fter flow adjustment, tighten the locking screw. 9
