The Fisher C1 pneumatic controller from Emerson is an “
energy-responsible” choice for oil and
gas operations. It can decrease
the amount of pressurized air or
natural gas lost to the atmosphere with its low consumption. A
green label and green Bourdon
tube symbolize the C1’s energy
and economics benefits. By identifying and replacing a high-con-sumption device with the C1,
increased profits from additional
gas sales are realized. Users can
save 1,000 to 5,000 cubic meters
of methane per year—$350 to
$1,400 according to the U.S.
Natural Gas STAR program.

Automatic Balance and Modulating
ITT Bell & Gossett introduces the OPTIFLO valve, which
combines an externally field-adjustable automatic balance
valve and a full modulating control valve with 100% valve
authority. The valve maintains the set flow regardless of
fluctuations in system pressure; it is available in sizes from
½ to 1¼ inches. It provides the end user with great flexibility if the system is changed after initial installation and
eliminates the need to calculate valve authority, as the
innovative combination of the valve and actuator ensures
100% authority at all times. This energy-efficient balancing device helps minimize the cost to operate HVAC systems, making it an essential part of any “green” building.

Ball Valves Control Fugitive
The 40 Series, 40G Series and 60 Series of ball valves
from Swagelok are designed to control fugitive emissions
through body seal design and stem seal design. Fugitive
emissions are defined many ways—not confined to a stack,
duct or vent—including emissions from bulk handling or
processing of raw materials, windblown dust and other

Paper No. 410
Crane Technical Paper No. 410
(TP-410) is the quintessential guide
to understanding the flow of fluid
through valves, pipes and fittings,
enabling selection of the correct
equipment for a piping system.
Originally developed in 1942, the 2009 edition of
Crane TP-410 has been fully updated to reflect the latest knowledge and research in the fluid handling industry. The TP-410 has served as an indispensable technical
resource for more than 60 years to specifying engineers,
designers and engineering students.
For the 2009 edition, additional valves and their
resistance coefficients were added based on tests performed within the Crane Engineering Laboratories.
Industry research was gathered on the latest calculation
methods for hydraulic resistance and in resistance values for wyes and tees. Chapters on pumps, control valves
and flow meters were included and over 35 new sources
have been added to the book.
