2) Usage of manifold
(1) The PR port is a pilot exhaust port.
(2) When operating six or more valve stations at the same time, be sure to install
an air supply / exhaust block on each side of the manifold block to receive
air-supply pressure (P) from both ends. Also, open both exhaust (R) ends to
atmosphere.
(3) The adjoining cylinder may pop out by back pressure when driving the sin-
gle-acting cylinder with 3-position A-B-R parts connected (4KB140) or 3-port
valve in the manifold. To prevent this, use the unit only for the solenoid
valve of this circuit, or activate another solenoid valve after energizing this
solenoid valve.
(4) Use pipes for the P port matching the port size of the manifold. The lack of
flow volume or pressure may cause the valve to malfunction or reduce the
cylinder thrust.
