Technical Remarks
■	The pressure dew point must be at least 15 °C under ambient and medium temperature and may not exceed 3 °C.
■	The oil content of compressed air must remain constant during the life cycle.
■	Use only the approved oils from Bosch Rexroth, see chapter „Technical information“.
■	See the following pages on the series for technical data on individual components.
■	For technical data for electronics (link structures), see the Chapter "Field bus connections".
■	The flow of the individual valves depends on the base plate, so here the flow is 700 l/min.
■	For push-in fittings, only use plug accessories made of plastic (polyamide) from our catalog.
■	It is necessary to maintain the electrical current in the coil of double solenoid valves to avoid unexpected auto-switching.

Configurable product
	This product is configurable. Please use the Internet configurator or contact the nearest Bosch Rexroth sales office.
