EB 5866 EN 5Safety instructions and measures1 Safety instructions and measuresIntended useThe SAMSON Type 3222 Valve is designed for use in temperature control circuits in HVACplants (e.g. for DHW heating). The valve is primarily combined with the following SAMSONactuators:− As electric control valve: Type 3222/5857, Type 3222/5824, Type 3222/5825,Type 3222/5757-3, Type 3222/5757-7, Type 3222/5724-3, Type 3222/5724-8,Type 3222/5725-3, Type 3222/5725-7 and Type 3222/5725-8− As pneumatic control valve: Type 3222/2780The valve with its actuator is designed to operate under exactly defined conditions (e.g. oper-ating pressure, process medium, temperature). Therefore, operators must ensure that the con-trol valve is only used in applications that meet the specifications used for sizing the valve atthe ordering stage. In case operators intend to use the control valve in other applications orconditions than specified, SAMSON must be contacted.SAMSON does not assume any liability for damage resulting from the failure to use thevalve for its intended purpose or for damage caused by external forces or any other externalfactors.Î Refer to the technical data and nameplate for limits and fields of application as well aspossible uses.Reasonably foreseeable misuseThe control valve is not suitable for the following applications:− Use outside the limits defined during sizing and in the technical data− For Type 3222/2780 Control Valve: use outside the limits defined by the valve accesso-ries mounted on the control valveFurthermore, the following activities do not comply with the intended use:− Use of non-original spare parts− Performing servicing and repair work not described in these instructions
