Note 2) Synthesized effective area with solenoid valve 2 position single type. Note 3) . Operate an interface regulator only by applying pressure from the “P” port of the base, except when using it as a reverse pressure valve. . To combine a pressure center valve and the A and B port pressure reduction of an interface regulator, use the ARBF3000, 4000, or 5000 model. . To combine a reverse pressure valve and an interface regulator, use the ARBF3000, 4000, or 5000 model. Furthermore, the P port pressure reduction cannot be used for the reverse pressure valve. . When combining a double check valve and an interface regulator, use a manifold or sub-plate as a basis, and stack them in the following order; the perfect spacer → the interface regulator → the valve. . When a closed center valve is combined with the interface regulator's A, B port regulation, note that it cannot be used for intermediate stops of a cylinder because there is leakage from relief port on the regulator. Note 4) Note that the pressure gauge (G27) for the ARBF2000-00-P-�ｭ cannot be used for the oil lubricating air.
