CHARACTERISTICS

The SK 51 is a float trap dedicated to the draining of condensate in steam lines. The SK51 has a ductile iron body with either PN16/25 flanged or BSP threaded connections with face to face dimensions complying with the DIN 2533 standard. This steam trap can drain large quantities of condensate and is well adapted to flow rate changes. Consequently, it is recommended for process draining in heat exchangers, autoclaves, and condensers in the field of chemical processing and food and drugs industries. The standard version of the SK51 is equipped with a thermostatic capsule for air elimination at start-up. It must be installed horizontally and several mechanisms are available depending on the pressure differential. LIMITS OF USE

Max. allowable pressure (PS) 16 bar

Max. allowable temperature (TS) 250 °C

CHARACTERISTICS The SPR40 separator is used to eliminate water, oil and dust particles on steam and compressed air distribution pipework. It permits to get a clean fluid and protects the downstream sensitive equipment such as pressure reducers, control valves, instrumentation equipment. In case of use on steam, it permits to get a dry steam and thus improves heat exchange efficiency. The SPR separator is dimensioned according to the AD Merkblatt 2000 code and the EC 97/23 Directive. It has a carbon steel construction with flanged connections. The device lowest point has to be equipped with a condensate drain for steam and liquid drain for compressed air. The highest point can be equipped with various accessories. It is necessary to think about an adequate support of the separator, based on its weight.

INSTRUCTIONS FOR INSTALLATION

The SK51 steam trap has to be installed lower than the pipework to drain. It is delivered for a horizontal mounting standard. The SK51 can be delivered for a vertical installation, on request only. Upstream from the steam trap, it is recommended to install a Y strainer in order to avoid damages caused by impurities on the steam trap seat. The steam trap outlet has to be connected to the condensate return system or directed to waste. In this case, please respect the maximum temperature allowance for the environment.

The SK steam trap mounting position is very important for its effective operation. 2 mounting instructions should be respected: 1/ The SK has to be installed in a horizontal position, following the direction of the arrow marked on the body: steam upstream and condensate downstream. 2/ The arrow marked on the nameplate has to point downwards. Before installing the steam trap, isolate and depressurize the line. Please wait until the complete cooling of the system. Carefully clean the upstream piping. Fix the steam trap on the pipes after having checked the above mounting instructions.

For the flanged SK steam trap, please choose flange gaskets that are adapted to the use on steam. Use the below nut type:

DISMANTLING AND MAINTENANCE

It is not necessary to remove the steam trap to proceed to its maintenance.

1. Shut the upstream isolating valve off. 2. Drain the downstream piping. 3. Please make sure that there is no pressure

and no temperature. 4. Unscrew the 4 screws and remove cover

(mark 2 on the drawing, page 1). 5. Check the float (mark 8) and the whole

mechanism conditions, particularly the seat condition (mark 6). Clean and repair the damaged pieces if necessary.

6. Check the thermostatic air eliminator (mark 4) and the seat condition. Replace the air eliminator if necessary and clean the seat.

7. Remount the cover (mark 2) by changing the body gasket (mark 3).
