McIlvaine is forecasting valve types down to the smallest sub segment and we need your help

The McIlvaine Industrial Valves: World Market report contains 100,000 revenue forecasts by valve type, industry, country and year. Each valve type is further segmented by control vs. on/off.

McIlvaine also provides custom forecasting with more detail. We are trying to segment valves by seating type, entry, manual vs. actuated and for ball valves to also determine the ratio of floating to trunnion.

We would like your help in adding your estimate of the ratio for any of the following categories. The % in black are the original numbers by McIlvaine. The numbers in red have been supplied by a pipeline expert. Just reply to this email with your estimates and we will publish them in the next Valve Insights.

Analysis Of Ball Valve Design Option Popularity % Ratio
Type	Seat-Soft to metal ratio	Entry-side to top	Floating/trunnion
Pipeline	98	98 80	90
Well Head		95
Sub Sea		5
FPSO		80
Cryo Tanker		40
Oil Tanker		90
Gas Processing		85

The numbers in red were furnished by Brian G Thompson-Australian Valve God Global Supply Line/Australian Pipeline Valve - Managing Director & Owner. He furnished the ratio based on the # of units. The McIlvaine % is based on revenue. So if McIlvaine #s are adjusted to units, the number would be 90 percent but still lower than Brian’s estimate.

We contacted Brian as a result of his article in the Valve World Valve Group. Here are his interesting comments on oil and gas valves:

· Global Supply Line (GSL) is a leading supplier, stocking and distributing valves as well as pipeline and oilfield products worldwide. GSL is renowned worldwide as a stockist and indentor of specialty valves.

In lieu of expensive custom made metal to metal seated ball valves, APV and GSL’s other manufacturers produce full circular port compact top entry metal seated, lubricated and non-lubricated plug valves for dirty and problem service applications for pipelines, manifolds and wellheads.

One of the valves manufactured is the Daflon valve. This plug/ball valve is a full circular port compact top entry metal seated plug valve manufactured up to 2500 class as well as API 2,000 to 10,000 PSI. This valve does not have to rely on springs behind the seats like a trunnion ball valve that could jam or fail. Furthermore, the pressure balanced Daflon valve will not relieve pressure upstream during pressure differentials like a trunnion ball valve so both seats always maintain a seal. The Daflon valve is also available in a single body dual plug double block and bleed configuration. These valves are similar to Texsteam™ style plug valves.

In addition, APV and GSL’s suppliers can manufacture trunnion ball valves that have seats that lift away from the ball during turning to avoid seat damage. Not only in Orbit® style rising stem style ball valves but also conventional quarter turn trunnion ball valves. Two types: cam action ball and moving seat.

The above valves offer a cheaper alternative to metal seated ball valves while also providing a bubble tight, soft seat. Furthermore, if you are finding you constantly have to change out seats on your soft seat trunnion valves, APV and our other manufacturers have options:

Instead of replacing the entire metal seat with soft seat insert APV and other GSL brands can supply O-ring backed PTFE/Devlon seat insert which means only the insert needs to be replaced (easy to replace).

APV can also supply floating ball valves with energised seats. The seats are pure PTFE or Devlon like a floating ball but are side sealing and energised by a wave washer or large O-ring.

Floating ball with metal seats and soft seat inserts can also be supplied (energised or non-energised). With this design you can still use the valves for double block and bleed but without the extra complexity of seat O-rings, springs, trunnion seals and bearings, etc. which can cause problems due to chemicals, temperature or jamming/damage due to impurities in media. Click here for APV catalogues.

For clients not requiring double block and bleed or a full port piggable valve another option is high performance triple offset (triple eccentric) butterfly valves metal-to-metal seat. These valves are still cheaper than trunnion mounted valves and are a much longer lasting option. The laminated metal to metal seat design can still accommodate bubble tight shut off but unlike soft seated valves provides bubble seated shut off for the life of the valve and is not subject to damage from standard particulates from the medium such is the case with trunnion mounted soft seat insert ball valves. These valves are fire safe and also have other advantages in that they do not have seat O-rings, springs, etc. that can be damaged by particulates in the media/temperature/chemicals. These valves are available. Click here to refer to the APV Catalogue section of our website.

Sales of gas turbine intake filters will double over the next six years according to the McIlvaine Company. The high rate of revenue growth will be a function of not only robust unit growth but double digit growth in the revenue per unit.

Gas turbine power generation is increasingly attractive due to the low price of natural gas, the environmental restrictions on coal-fired power and the ability for system suppliers to deliver new plants within 24 months. The latest high performance turbines provide improved efficiency and lower CO₂ emissions per unit of energy produced. However, the rotating equipment is subject to substantial corrosion and erosion from small particles.

As a result, the industry is moving from lower cost filters to those with HEPA efficiency. These filters often cost twice that of the lower efficiency filters and have somewhat shorter lives. This additional cost is more than offset by lower part replacement and less frequent washing. The specific climactic conditions vary from the arctic to the desert and from relatively clean air to air contaminated by hydrocarbons and fine particulate or salt water spray in the case of turbines on offshore rigs and coastal locations.

There are multiple approaches used to remove the air contaminants. In general they can be divided into static and pulsed filter systems. In static filter systems, there is a pre filter which captures most of the dust. It is low in cost and frequently replaced. The downstream high efficiency filter has a long life time due to the lower dust concentration to which it is exposed. There is a significant quantity of microglass media used in the high efficiency filters.

The pulsed filter approach provides filtration of coarse and fine particles in one device. The filter surface is periodically cleaned with a reverse pulse of air. Membrane filter media is commonly used with this approach.

NAFTA is the largest regional market with 34 percent of the gas turbine installed base. Western Europe is the next largest segment but plants are shutting down there because of the high cost of gas in the region.

The 2016 world market for food filtration and separation hardware and consumables will exceed $2.9 billion. This is the conclusion of the McIlvaine Company through iteration of data in a number of its related reports.

The expenditure for consumables will be nearly twice the hardware investment. One-third of the consumables expenditures will be for replacement cartridges followed by cross-flow filtration membranes. The third largest purchase will be for filter cloths, followed next by filter bags. Rounding out the consumables list are ion exchange resins and filter belts.

Ranking	Hardware Type
1	Centrifuges
2	Cross-flow filtration hardware
3	Filter presses
4	Cartridge hardware e.g. housings
5	Bag hardware e.g. housings
6	Leaf, gravity and drum filters

The largest application segment is dairy, fruits and vegetables, sugar beet, corn and grain. Dairy represents more than one-third of the total in this segment. Separation of milk and cream in centrifuges is one of the oldest applications. Membrane technology is replacing leaf filters with diatomaceous earth in many plants in this category.

The market is growing at rates slightly above that of GDP as filtration is used to create new products as well as improve the quality of existing products. Fat free and non-alcoholic beverages are two examples of new products created by filtration and separation.

A few centrifuge suppliers dominate this hardware segment. At the other end of the spectrum, there are thousands of companies sharing the consumable cartridge market in the food industry.

McIlvaine derives its food filtration and separation forecasts by extracting information and insights from the following reports:

Alternatively to purchasing the individual reports, one can choose to purchase application focused reports such as Food Filtration and Separation.
