To use the external pilot system, remove the mounting bolts from the head and rotate the head 180°, and then retighten the returned bolts.● If the valve is rotated 180° horizontally, the circuit can use A line. ● Can also be used as a sequence valve.■ SpecificationsMaximum operating pressureMPaModelECB-1ECB-270● Enables a reverse flow by applying pressure 1/10 of the secondary-side pressure to the pilot　pressure port.Maximum operating pressureMPaModelECH-470■ECH-4● The tightening torque of the bolts must be 12 to 13 N·m. ● The screw-in length of for the mounting bolts must be 9 to 10 mm.
