4. STEAM SUPPLY CONNECTIONS

4.1 Control valves (SAKV******) kits for

pressurized steam supplies

A control valve is needed to regulate the flow 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 significant 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 specifications” manual.

4.2 Fitting kits (SAKR******) for threaded

control valves

Note:

For flanged control valves, the installer must provide the

appropriate fittings and piping to connect the valve to the

ultimateSAM distributor. For control valves having threaded connections,
optional fitting 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 fitting kits are shown in table 4.c.

4.3 Actuator Kit for control valves

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.
