Note 2) Pressure of the pilot X port must be the same as that of the release port 1 (P) or more. Adsorption Transfer System Circuit Example 2 spool valves included. Possible to control vacuum adsorption and release by a valve. Current consumption.15 W (With energy saving circuit) Width 1 mm (Same as Series SJ) With throttle valve that can control the flow rate of release air Replaceable filters are built in the vacuum side and release side respectively With a pressure detection port that enables users to connect a pressure switch, etc. Can be mounted with a 4 port valve SJ2/ (ade to Order). (Please contact SC for details.) Possible to switch pressure of two wiring systems by applying different positive pressures to 1 (P) port and /5 (E). (In this case, flow rate is adjustable only at the P port side.)
