Notes on Operation Mounting Bolts (JIS B 1176, Strength Class 12.9)

• Mounting bolts must be ordered separately.• For mounting bolt lengths, see page G10-1 (EPMX2-3) or

G22-4 (EPMX2-5).• Mounting bolt tightening torque

• Mounting orientationThe mounting direction is not subject to any restrictions, but the valve characteristics may differ slightly depending on this direction.

• Air bleedFor stable pressure control, loosen the air bleed plug and bleed air completely out of the valve prior to use.

• Manual adjustmentIn case there is no input current to the solenoid during initial adjustment or electric malfunction, pressure may be set manually with the pressure adjustment knob. Return knob to counterclockwise direction upon electro-magnetic control.

• In order to exercise satisfactory control, provide a pressure difference of at least 1.5 MPa between the high pressure side and reduced pressure side.
