2021 – Swanson Flo is acquired by MCE to continue to service our customers with an extended offering of highly-engineered, technical solutions by providing leading process control products and services.

Brewery Valve Application Guide

Download the Brewery Valve
Application Guide Here
Today, beer is one of the oldest beverages humans have ever produced and has spread all over the world. It is a product valued by its physicochemical properties as in its quality and traditional link with culinary and ethnic distinctiveness.

Many types of valves are commonly used in a brewery to regulate the flow of fluids throughout process pipes in a plant.

One type is the diaphragm valve, in which a soft diaphragm is pushed against a bell-shaped feature using a mechanical screw . This mechanism allows gas or liquid flow to be controlled within the valve’s total variability, but the flow pressure tolerances are fairly tight.

The butterfly valve is the next most commonly used valve in breweries due to its compact design and wide pressure and flow tolerances. It consists of a metal disc which rotates within the body of the valve and closes against a rubber seal. Its flow-through design makes it easy to clean.

The Brewery Valve Application Guide, located on Swanson Flo web site, provides a quick reference on the various processes involved in brewing and what type of valves are used for those processes.

Hazardous Area Classifications in the USA

Hazardous Area Classifications
Understanding Hazardous Area classifications is critical.
An important aspect of safe installation is to determine the hazardous area classification in the area. Checking the area classification is also important for safe electrical wiring. The hazardous area classification should be known by personnel before starting work in an area.

Hazardous areas refer to locations with a possible risk of explosion or fire due to dangerous atmosphere. The hazards can be associated with flammable vapors or gases, ignitable fibers, and combustible dusts.

Different hazardous area classifications exist in the North America and Europe. Generally, the National Electric Code (NEC) classifications govern hazardous areas in the US. While in Europe, hazardous area classification has been specified by the International Electrotechnical Commission (IEC).

CLASS
NATURE OF HAZARDOUS MATERIAL
CLASS I
Hazardous area due the presence of flammable vapors or gases in sufficient quantities to produce ignitable mixtures and cause an explosion.
Examples include natural gas and liquified petroleum.
CLASS II
Hazardous area due the presence of conductive or combustible dusts in sufficient quantities to produce ignitable mixtures and cause an explosion.
Examples include aluminum and magnesium powders.
CLASS III
Hazardous area due the presence of flammable fibers or other flying debris that collect around lighting fixtures, machinery, and other areas in sufficient quantities to produce ignitable mixtures and cause an explosion.
Examples include sawdust and flyings



Division groups hazardous areas based on the chances of an explosion due to the presence of flammable materials in the area.

DIVISION
LIKELIHOOD OF HAZARDOUS MATERIAL
DIVISION 1
Areas where there is a high chance of an explosion due to hazardous material that is present periodically, intermittently, or continuously under normal operation.
DIVISION 2
Areas where there is a low chance of an explosion under normal operation.


Group categorizes areas based on the type of flammable or ignitable materials in the environment. As per NEC guidelines, Groups A to D classify gasses while Groups E to G classify dust and flying debris.
GROUP
TYPE OF HAZARDOUS MATERIAL IN THE AREA
GROUP A
Acetylene.
GROUP B
Area contains flammable gas, liquid, or liquid produced vapor with any of the following characteristics:
  • Minimum Ignition Current (MIC) value equal to or less than 0.40
  • Maximum Experimental Safe Gap (MESG) value equal to or less than 0.45 mm
  • Combustible gas with more than 30 percent volume
Examples include hydrogen, ethylene oxide, acrolein, propylene oxide.

GROUP C
Area contains flammable gas, liquid, or liquid produced vapor with any of the following characteristics:
  • Minimum Ignition Current (MIC) value between 0.40 and 0.80
  • Maximum Experimental Safe Gap (MESG) value greater than 0.75 mm
Examples include carbon monoxide, hydrogen sulphide, ether, cyclopropane, morphline, acetaldehyde, isoprene, and ethylene.

GROUP D
Area contains flammable gas, liquid, or liquid produced vapor with any of the following characteristics:
  • Minimum Ignition Current (MIC) value greater than 0.80
  • Maximum Experimental Safe Gap (MESG) value greater than 0.75 mm
Examples include ammonia, gasoline, butane, benzene, hexane, ethanol, methane, methanol, natural gas, propane, naphtha, and vinyl chloride.

GROUP E
Area contains metal dusts such as magnesium, aluminum, chromium, bronze, titanium, zinc, and other combustible dusts whose abrasiveness, size, and conductivity present a hazard.

GROUP F
Area contains carbonaceous dusts such as charcoal, coal black, carbon black, coke dusts and others that present an explosion hazard.
GROUP G
Area contains combustible dusts not classified in Groups E and F.
Examples include starch, grain, flour, wood, plastic, sugar, and chemicals.


NOTE: This post serves only as a guide to acquaint the reader with hazardous area classifications in the USA. It is imperative to discuss your instrumentation, valve, or process equipment requirement with a qualified applications expert prior to installing any electrical device inside of any hazardous area.
