The 595 Series Relay Valve is a high-capacity, solenoid operated two way valve with 3/8" NPT connections for applications when flows of 75-150 SCFM are required. It is used in numerous rail air-control applications including horn actuation, automatic emer gency dumping and snow blasting. The unique integral pipe bracket with 3/8" NPT porting is standard and permits easy maintenance as required. No air connections need to be disconnected when maintenance is required saving out-of-service time for your equipment. The 595 Series electro-pneumatic valve is actuated electrically from the cab console or some other automatic-programmable signal. The heavy-duty design with epoxy impregnated and encapsulated "Class F continuous duty" coils are commonly used in the locomotive and rail transit industry with a variety of DC and AC input voltages. Faston tab or a terminal block connection, with or without suppression devices, are available along with a choice of coil housing and/or exposed coil with yoke. Special electrical connectors can be specified. Straight pneumatic configurations, like the 595-E, are available as well.
