Intended use
The Type 42-10 RS Check Valve is suitable for backflow protection in networks containing
water, steam, nitrogen or compressed air up to 220 °C. It consists of a Type 2412 RS Valve
and a Type 2420 RS Actuator.
The Type 42-10 RS Check Valve is mainly used in industrial plants.
The regulator is designed to operate under exactly defined conditions (e.g. operating pres-
sure, process medium, temperature). Therefore, operators must ensure that the regulators are
only used in operating conditions that meet the specifications used for sizing the devices at
the ordering stage. In case operators intend to use the regulators in other applications or
conditions than specified, contact SAMSON.
SAMSON does not assume any liability for damage resulting from the failure to use the de-
vice for its intended purpose or for damage caused by external forces or any other external
factors.
Î Refer to the technical data and nameplate for limits and fields of application as well as
possible uses.

− Use of non-original spare parts
− Performing service and repair work not described
Qualifications of operating personnel
The regulator must be mounted, started up, serviced and repaired by fully trained and
qualified personnel only; the accepted industry codes and practices must be observed.
