A Smart Grid
Communications System
for Water Management
A cost-effective and innovative new
option for building AMR/AMI smart
grid communications for water management is now available for utilities:
The Mi.Hydrant interface unit from
Mueller Systems is an enclosed transceiver that replaces the pumper cap of
existing fire hydrants and provides multi-path RF coverage. It stores meter data
in internal memory and transmits it to
other devices within the Mi.Net Mueller Infrastructure
Network for Utilities AMI system. When employed in a
multi-path configuration, the interface extends its two-way
network coverage by relaying data between meters
equipped with the units.
Utilities can reduce equipment and labor costs, and
eliminate the need to navigate the procedures, politics and
logistics of locating and installing additional structures on
which to place communication devices.
The FCC-compliant Mi.Hydrant features open architecture, so while ideally deployed in a fire hydrant from
Mueller Co., it can also be used with other brand fire
hydrants. This enables utilities to transition in a scaled,
cost-effective manner.

Fire-Safe
Valve/Vent Drain
Combination
Conval announces the availability of the Clampseal Fire-Safe
Valve factory-equipped with an
SaVD Safe Vent Drain. This
combination is suitable for
refining and chemical plants
where fire safety is a major
concern; the product is available in Y, A and T pattern configurations in 1/2 inch through 4 inch sizes, with up to
ASME/ANSI 2500 pressure ratings, and with NPT, butt
weld and socket weld ends.
This fire-safe valve contains a simple mechanism that
compensates for thermal expansion. As a result of this and
other design features, the valve meets API fire-safe
standards by extremely high margins. In brief, the testing
procedure calls for the test valve to be placed in line and
pressurized to 75% of rated pressure, then subjected to a
1,400 to 1,800° F (760 to 982° C) fire for 30 minutes.
The valve is then quenched with water to cool it to ambient
temperature, cycled to prove operability, and then subjected to further pressure testing.

Metal Seated
Ball Valves
CRANE ChemPharma
Flow Solutions has
introduced a line of
Krombach Metal Seated Ball Valves (MSBV)
designed for specialty
chemical and mining applications. It features a two-piece
design with a flange connection. The MSBV’s ball and seat
are machined to such precise tolerances that ball and
seat lapping does not have to be performed individually for
each valve—making both the ball and seat freely interchangeable (if equal in nominal size). The trunnion-mounted ball design offers a polygon stem-to-ball connection
that reduces stress and ensures optimal torque transmission. An additional feature is its self-cleaning system,
which removes excess particles, minimizes leakage and
extends product life.
Other options include a fire-safe design body gasket and
removable hand lever. To ensure that this product meets
the considerably higher benchmark of leak protection
required for isolation service, it is typically tested for 60
minutes at 300 psig Nitrogen with a permissible leakage
rate of class VI.

Expanded Slam Shut
Valve Line
Dresser’s Mooney Slam Shut Valve
line has now been expanded to
include a 1-inch linear plug design
and rotary design sizes to 4 inches.
The 2-, 3- and 4-inch sizes can be integrated into a Flowgrid Regulator or can
stand alone.
The valve is a unique pneumatically actuated
device that provides accurate over and/or under downstream pressure protection. Its patent-pending design
guarantees a snap-acting release of the latch only when
designated set points are exceeded. This eliminates costly
“accidental shutoffs” from vibration or conditions other
than over/under pressures. A positive shutoff is achieved
instantly with zero pressure differential requirements and
an easy reset can be completed with common hand tools.
