4. STEAM SUPPLY CONNECTIONS
4.1 Control valves (SAKV******) kits for
pressurized steam supplies
A control valve is needed to regulate the fl ow of pressurized steam
to an ultimateSAM distributor. Actuators for the control valve are
sold separately. If a valve and actuator kit was not ordered with the
ultimateSAM distributor, refer to the design manual for information on
how to size and select a control valves and actuators. Information on
actuators is provided in section 4.2.
The codes for valve kits are shown in table 4.a.

Tab. 4.b
If the inlet pressure to the control valve is greater than 0.7 bar (10 psig),
the valve may generate signifi cant noise due to the near sonic velocity of
the steam. (See section 6.1 of the design manual for more information.)
Because the noise and coincident vibration may shorten valve life,
frequent inspections of the valve may be required.
For information about the weight, dimensions, construction materials,
and rangeability of each valve, see the “Technical specifi cations” manual.
4.2 Fitting kits (SAKR******) for threaded
control valves
Nota: For fl anged control valves, the installer must provide the
appropriate fi ttings and piping to connect the valve to the
ultimateSAM distributor.
For control valves having threaded connections, optional fi tting kits are
available to facilitate the connection of the valve to both the distributor inlet
and the steam traps and strainers (section 4.3). The codes for the fi tting kits are
shown in table 4.c.

4.3 Kit attuatori per valvole di regolazione
Each control valve needs an actuator to control its motion. The system for
identifying actuator kits is shown in Table 4.e.
Note: Not all of the possible
combinations shown on the table are available. Tables 4.f and 4.g indicate
which electronic or pneumatic actuator can be paired with which control
valve.
