Twin Parallel
Actaris / Schlumberger Twin Parallel Flow Regulators
incorporate two diaphragm actuators and a single valve body into a
self-contained regulator. Parallel regulation through dual orifices allows
increased capacities. Twin relief valves (spring loaded models) provide double
relief capacity. The use of two smaller orifices in place of one large orifice
improves lockup, inlet effect performance, and relief performance. The Internal
Monitor versions of the twin regulators provide the highest level of safety
available in a single regulating device. Twin sliding orifices provide normal
dual regulation, with secondary monitor regulation and lockup in the even to
multiple internal seat failures and/or a single diaphragm or lever failure.
B531 Series
The B531 is designed for light to medium commercial applications where the
added safety of twin sliding orifices and/or dual relief is desirable. The
IM version can perform all of the functions of a conventional monitor set in
a single device. Small diaphragm cases allow the B531 to respond quickly to
fast on/off loads. Typical applications include schools, day care centers,
nursing homes, and high-traffic areas such as drive-thru restaurants and car
washes. |

B838 Series
The B838 is designed for large commercial and industrial applications where
the added safety of twin sliding orifices and/or dual relief is desirable.
The increased capacity inherent in parallel flow regulators enables the B838
to handle large loads even at delivery pressures of 2 and 5 psig. The 838
can thus address fixed factor needs while retaining all of the favorable
characteristics of spring loaded regulators such as quick response, low
lockup, and internal relief. Typical applications include hospitals,
apartment buildings, hotels, high-rises, and public buildings.

CL838 Series
The CL838 is designed to provide extremely accurate regulation of gas in
high capacity, elevated outlet pressure applications. The Internal Monitor
version can perform all of the functions of a conventional high pressure
monitor set in a single device. Typical applications include district
stations and high capacity fixed factor installations.

B34 Series
The B34 service regulator is a versatile, large diaphragm-controlled
regulator designed for commercial and industrial loads. The B34 maintains
accurate regulation on applications where frequent sudden load changes can
occur. Rugged construction enables the basic B34 model to cover applications
with outlet pressures of Inches W.C. through 5 psig by merely changing
adjustment springs. |
|
B38 Series
The B38 service regulator is designed for use on large commercial and
industrial loads. Large orifices are available (up to 1 3/8") for high
capacity/low inlet pressure applications. An added feature of the B38R is
its massive relief capacity. All choke points in the relief flow path are
enlarged to ensure a minimum pressure buildup in the event of regulator
failure. The need for external relief valves for full capacity relief is
eliminated in most applications. |
