SPOTLIGHT ON

Manufacturing high-quality U.S. and Canadian valves and actuators, and keeping the flow control chain in which they are used operating in the most efficient manner possible begins with the right ingredients, the right tools and the right support. For that reason, suppliers to valve and actuator companies play a critical role. The array of products and services those suppliers provide ranges from high-tech instrumentation, the latest in monitoring and control devices, and seals and gaskets, to high-quality coatings and age-old castings. A look at some of the latest products reveals how broad the field of valve and actuator supply is. For a closer look, visit VMA.org and click on the Product Finders link. There, you’ll find a handy tool that can help you narrow and focus your search for the very best ingredients.

TITANIUM
COATINGS

Hardide Coatings has made a significant technological breakthrough by successfully developing a new Hardide coating process specifically for titanium. The company,

which develops tungsten carbide-based coatings, has successfully coated its first titanium components for customers. As a result, components manufactured from titanium now can have the unique wear, abrasion and chemical-resistant properties of Hardide.

The titanium project has been in research and development for five years but was fast-tracked over the last year to meet increasing customer demand from the aerospace, defense and Formula 1 industries. Hardide Coatings is now processing small-scale commercial applications for customers in these sectors and plans to treat regular batches of volume parts later this year.

FLAME ARRESTER
PROTECTS
AGAINST
DETONATIONS

Groth Corp. introduces its

Model 7758A Detonation and

Deflagration Flame Arrester.

Designed to protect liquid storage tanks containing vapors with MESG equal to or greater than 0.025” (0.65 mm), this product also protects against unstable detonations, deflagrations, short-time burn and endurance burn (with temperature sensor) for NEC group C and D vapors (IEC explosion groups IIB3, IIB2, IIB1 and IIA).

The Groth Model 7758A Flame/Detonation Arrester is available in standard flange sizes of 2 to 12 inches and in carbon steel, stainless steel or Hastelloy C. Other materials are available upon request. This new product, tested and approved for elevated pre-ignition pressures, can be ordered with facto-ry-installed temperature sensors.

MASS FLOW CONTROLLER IMMUNE TO PRESSURE AND TEMPERATURE FLUCTUATIONS

Brooks Instrument has released the
B-Series mass flow controller, a
new family of mass flow products
designed to be insensitive to pres-
sure and temperature fluctuations. Built on a standard 1.125-
inch-wide platform with a powerful user interface and local
digital display, the B-Series provides a compact flow measure-
ment and control solution that eliminates the costly tempera-
ture and pressure control devices and systems.

The mass flow controller actively measures line pressure and adjusts the control valve to virtually eliminate actual flow and flow signal changes that result from pressure fluctuations. In addition, the output of every B-Series mass flow controller is characterized over the full operating temperature range of the device allowing superior measurement and control accuracy regardless of process or ambient temperature conditions.

BOOSTER FOR CONTROL VALVES

A new booster design that eliminates the time-consuming trial and error procedures often required for fine tuning control valves, is the latest product to be introduced by Samson Controls. With its bypass restriction, the booster can be adjusted exactly and lead-sealed in this set-up, resulting in valuable time saved, while also minimizing potential start-up problems.

As the booster is completely pressure balanced it provides a stable output, even under fluctuating pressure conditions. The signal pressure is transmitted with a defined hysteresis, without loss (gain 1: 1) and emits minimal noise. Another important benefit is that only the booster’s functional parts come into contact with instrument air, alternatively the boost-er's exhaust air port can be protected from the weather or other environmental factors.
