Valve SD3EX-B2
Valve SD3EX-C2
The valve complies with the relevant requirements of legislation and standards as amended:
ČSN EN ISO 4413
Hydraulics - General rules and safety requirements for hydraulic systems and their components
Other regulations and standards used:
ČSN ISO 6403 Hydrostatic drives. Valves for flow and pressure control. Test methods
ČSN ISO 4411 Measurement of the characteristics Δp = function (Q) of hydraulic valves
ČSN EN ISO 9001
Quality management systems
ČSN EN ISO 12100 Machine safety / risk analysis
Directive 2006/42/EU on machinery / used chapters: 1.7.4 Instructions for use, Annex III CE marking
ČSN EN 82079-1 Preparation of instruction manuals - Structure, content and presentation / Part 1: General principles and detailed requirements
4.7 Legislation and standards
An overview of possible valve modifications is described in the ordering code.
The number of spool positions, the spool connection and the type of emergency control and the electrical parameters of the coil cannot be
subsequently changed by the user.In the case of a valve with a 10 W coil, the coil surface temperature and the application for the temperature class
can be affected by adjusting the ambient temperature (see 4.4 Ambient temperature range for each class).
The coils with AC power supply and built-in rectifier are supplied with only the cable attached, with optional lengths of 3 and 8 m as standard.
