Overall dimensions and technical information are provided solely for informative purposes and may be modified without notice Direct operated solenoid valves Series 300 1 Air distribution 1 | 178 Series 300 General The direct operated solenoid valve is the interface between pneumatic and electronic. In fact, it is actuated by an electrical signal and in turn gives a pneumatic signal directly available for small users or for actuating bigger pneumatic distributors. A wide range of valves are needed for satisfying various applications. For this need we have available miniature components with very low volume and electrical impute as well as solenoid valves with large flow rate and power for heavy duty operations. These solenoid valves are usually 3/2, normally closed or normally open, but there are available the 2/2, closed or open, for vacuum and others. Note that the direct operated valves can only be used with bases, individual or multiple with M5 or G 1/8" thread or with connections. Some PNEUMAX solenoid valves are homologated valid for USA and Canada (file n. VAIU2.E206325, VAIU8.E206325). For more details, refer to the coding, in the following pages. The 10mm and 15mm solenoid valves are certified by UL in compliance with both Canadian and USA safety requirements as recognized component and included in the UL file E206325 and bear the “UL Recognized Component” marking. The 10mm and 15mm solenoid valves, since they are devices for “class 2 circuits”, according with UL standard UL 429/CSA C22.2 N°139, are not considered dangerous for electric shock or fire and thus a UL certification is not required for cables and connectors. Some solenoid valves, since they are devices for “class 2 circuits”, according with UL standard UL 429/CSA C22.2 N°139, are not considered dangerous for electric shock or fire and thus a UL certification is not required for cables and connectors. Use and maintenance Maintenance is normally not required for these components therefore the spare parts list is not provided. Their construction complexity and low cost do not make repair economically viable. It's easier and more economic to replace the complete valve in case of malfunction. For proper lubrication use only hydraulic oil class H such as Castrol type MAGNA GC 32.
