  • Basic Types of Industrial Gas Valves Everyone Should Know About

    Valves are essential components of almost any industrial machinery as they control the pressure and flow of the contents within a cylinder or any other materials such as tanks. Industrial gas valves are critical parts and must be maintained in proper condition, otherwise it could result in ultimate fall or deterioration of the complete system. In major industrial set-ups, certain mishaps are most likely to take place. To avoid these kind of catastrophic system failures, it is important that everyone (especially industrial workers) have a basic knowledge of major types of industrial valves.

    Industrial Gas Valves

    What are Valves?

    Valves are mechanical equipment that are used to control or regulate the flow of an industrial substance from its container (i.e. they can start, stop, increase or decrease the pressure of the flow). They are designed to be able to handle all varieties of materials like gases, liquids, or corrosive materials. Their versatility in function allows them to serve a wide variety of industries, including the petrochemical industry, manufacturing industry, and the compressed gas industry.

    Major Types of Valves

    Globe Valves: These valves have a disk that can start, stop, or throttle the flow of a pipeline. The disk works by moving from the seat to prevent water hammer and vibrations. The globe valves are linear motion valves that are mostly used as an on/off device or a regulating device in companies.

    Pressure Relief Valves: As the name implies, the pressure relief valves are industrial gas valves that prevent over-pressure situations that could possibly occur in high-pressure systems. The valve opens when there is an increase in the pressure so that more fluid can flow through. It ensures that an appropriate pressure is maintained while stabilizing operations.

    Ball Valves: Ball valves are fast-acting valves that use a rotating ball to transfer the material through a system. The rotating ball is responsible for opening and closing of the valve.

    Check Valves: It is a type of valves that maintains the flow of substances in one direction. It is a two-port device and uses a clapper that lifts to maintain a linear flow of fluids. In case the pressure tends to decrease or when the flow starts reversing its direction, the flapper closes the valve.

    Gate Valves:  Gate valves are bidirectional industrial gas valves that offer minimum flow restriction and are designed to start or stop a straight line flow. These valves are usually kept either fully closed or fully open. These valves are quite sensitive to vibrations when open and cannot be quickly opened or closed.

  • Important Tips for Safe Storage of CO2 Cylinders

    Storing compressed gas cylinders is a conscious and responsible job. As different gases have different properties and pose risks if mishandled, they need to be identified and stored with specific precautions. Specifically considering Carbon Dioxide cylinders, users must be aware of the possible hazards associated with CO2 and must be practically trained in safe practices of CO2 cylinder storage.

    Here’s a list of precautions to be taken while storing CO2 cylinders.

    • While storing empty CO2 cylinders, take care to close the valve tightly. The valve must be opened only when the gas is being used and closed when the gas is not in use.
    • It is generally recommended that CO2 cylinders must be stored standing on their base. However, many industries also store them lying on their side.
    • Avoid storing a charged CO2 cylinder in the cab portion of any vehicle or in a passenger vehicle.
    • Never store them in a place where they accidentally or knowingly become a part of the electrical circuit.
    • The pressure of your cylinder should be 880 psi (for brewing industry). The CO2 is cold enough to turn into a liquid at 880 psi
    • The storage area where CO2 cylinders are stored should:
    • Be free from a corrosive atmosphere and dry.
    • Be generously ventilated, because as little as 15% of the gas’ concentration would be responsible for unconsciousness within a minute.
    • Be away from direct heat (continuous or intermittent). A well-charged CO2 cylinder operates its safety relief devices when the pressure exceeds 2800-3000 psi and could escape through the safety relief device at a temperature of approximately 150°F (65.6°C). If the cylinder is slightly over-filled, it may escape even at a lower temperature. So, the ideal temperature to store these cylinders is below 125°F (51.7°C).
    • Be away from or protected from the edge of elevated areas, if the cylinder rolls it can cause hazardous damage to the cylinder, valve, property, or human beings in the nearing areas.
    • Be away from heavy traffic areas as in crowded places, the chances of accidents increase.


    Carbon Dioxide cylindersAll compressed gas cylinders including the Carbon Dioxide cylinders should be ideally secured using a chain or strap. Nesting of compressed gas cylinders is an equivalent safe storage mechanism that is used by the suppliers as well as distributor warehouses as it confirms that every cylinder has three points of contact – either the wall or other gas cylinders.

    At Evergreen Midwest, we offer CO2 cylinders th at can be relied upon for quality and industry specifications. With years of service to customers, we have been a trusted source of all industrial cylinders and our prompt product delivery is always appreciated by our clients.

  • How to Get Rid of that Extra Foamy Beer?

    Beer tastes great with that creamy head on the top, however sometimes you find that your glass is filled with extra foam that spurs up unnecessarily. If you face consistent foam problems, it is sure that there is some problem with your kegerator or maybe you are playing the pressure wrong.

    Let’s understand the physics behind foamy beer:

    Beer is a carbonated liquid, which means that more gas resides in the mixture at colder temperatures. The best temperature setting to preserve the original flavor of the beer is around 34-38 degrees but when the temperature starts rising above 40 degrees, CO2 tends to evacuate the beer and that results in the foam (most of the times).

    Once you know the temperature appropriations to be taken care of, the next thing to be worked on is the beer tap regulator settings. Under normal circumstances, beer can be pushed from 4PSI to 14 PSI and most kegerators deliver beer best between 5 PSI and 12 PSI. Exact pressure can be found out by analyzing your beer lines. You can push the beer at more pressure if the beer is colder or the inner diameter of the beer line is bigger. On the contrary, high temperature or high pressure can result in excess foam. If your beer lines are smaller i.e. about ¼" inner diameter, it can lead to a foamy texture.

    Now that you know the foam basics, you are good to pour in just the right beer in your glass. However, there are certain things to be observed:

    • The keg of a beer requires some time to settle after transportation. During commute of a few blocks by car, the temperature also tends to be changed. After reaching the destination, it is better to let the keg settle in for at least 2-4 hours before pouring.
    • Ensure that you use the proper pouring tilt which would help to reduce the foam due to an improper pour.
    • You may also have to check your beer lines and fittings. Dirty beer lines may also result in a foamy beer so it is important to keep your beer lines clean. Also, ensure that all your fittings are tight enough to prevent the outside air from being sucked into the beer solution that causes excess foaminess.
    • In some cases the length of the beer lines may cause extra foam. Ideally, six to eight feet of beer line is optimal.
    • If all of the above is right in place, there may be some problem with the regulator (dropped or banged). So, you need to fix the beer tap regulator malfunction first by contacting your nearest valve and regulator supplier to repair or replace it immediately.

  • #TechTuesday Exploring Alternative Fuel - Hydrogen

    tech tuesdayThe most abundant element in the universe, hydrogen is also a promising source of “clean” fuel on Earth. Named after the Greek words hydro for “water” and genes for “forming,” hydrogen makes up more than 90 percent of all of the atoms, which equals three quarters of the mass of the universe, according to the Los Alamo National Laboratory. Hydrogen is considered an alternative fuel under the Energy Policy Act of 1992. The interest in hydrogen as an alternative transportation fuel stems from its ability to power fuel cells in zero-emission electric vehicles, its potential for domestic production, and the fuel cell’s potential for high efficiency. In fact, a fuel cell is two to three times more efficient than an internal combustion engine running on gasoline. Hydrogen can also serve as fuel for internal combustion engines, but unlike with fuel cells, will produce tailpipe emissions and is less efficient.

  • #TechTuesday - What is Liquefied Natural Gas (LNG).

    tech tuesdayThis week, we are continuing our series on alternative fuels. In this issue we take a closer look at Liquefied Natural Gas (LNG).  Liquefied natural gas is an increasingly important pillar of the global energy industry. Long used to heat homes and power industry, natural gas is traditionally extracted from the ground and shipped through pipelines. But in recent decades, some of the world’s largest energy companies started shipping gas between continents by feeding those pipelines into enormous export terminals. There, the natural gas is run through a production “train” that super cools the gas into a liquid one-600th the size of its gaseous volume – essentially, from a beach ball of gas to a Ping-Pong ball of liquid thus creating Liquefied Natural Gas.

  • #TechTuesday - Exploring CNG, Compressed Natural Gas

    tech tuesday#TechTuesday. This week, we are continuing our series on alternative fuels. In this issue we take a closer look at Compressed Natural Gas (CNG). Natural Gas Fuel Basics - Natural gas is an odorless, nontoxic, gaseous mixture of hydrocarbons— predominantly methane (CH4). It accounts for about a quarter of the energy used in the United States. About one-third goes to residential and commercial uses, such as heating and cooking; one-third to industrial uses; and one-third to electric power production. Although natural gas is a clean-burning alternative fuel that has long been used to power natural gas vehicles, only about one tenth of 1% is used for transportation fuel.  To Learn More, Click Here: Tech Tuesday - CNG Alternative Fuel

  • #TechTuesday - Exploring Alternative Fuels

    tech tuesdayAlternative fuels are derived from resources other than petroleum. Some are produced domestically, reducing our dependence on imported oil, and some are derived from renewable sources. Often, they produce less pollution than gasoline or diesel. Alternative fuels include gaseous fuels such as hydrogen, natural gas, and propane; alcohols such as ethanol, methanol, and butanol; vegetable and waste-derived oils; and electricity. These fuels may be used in a dedicated system that burns a single fuel, or in a mixed system with other fuels including traditional gasoline or diesel, such as in hybrid-electric or flexible fuel vehicles. In this series we will be exploring four alternative fuels: Compressed Natural Gas (CNG), Liquefied Natural Gas (LNG), Liquefied Petroleum Gas or Propane (LPG) and Hydrogen (H2).
