Solstar air-valve islands use a plug-in system of electrical connections to reduce machine downtime. The systems allow small pilot valves to be quickly assembled onto a DIN rail-mounted interface valve island with transparent automatic addressing up to 16 valves. Solstar valves from Parker Hannifin Corp., Pneumatic Div., Richland, Mich., are recommended for piloting process-control valves, handling vacuum, or controlling small single-acting actuators for automation. The valves have a flow rating of 0.05 Cv. Solstar valve islands are connected to a PLC with subD25, 19-pin-round, or cable-gland connectors. With IP-65 protection on electrical connections, the islands can mount close to valves and actuators in industrial environments.
