Gas regulators are devices that are used to reduce the pressure of gases in a container or cylinder. These devices help to ensure the quality and purity of gas, as well as to prevent injury and damage to equipment. Gas regulators are made to be used with specific types of gas, such as propane.
The two main types of gas regulators that help to control the pressure of gas are the single state and the two stage regulators. The single stage regulator reduces pressure in one step, while the two stage regulator requires two steps in the pressure reduction process. When choosing a gas regulator, it is imperative to understand which stage of regulator is required for a specific type of machinery or application.
Other types of gas regulators include high pressure regulators, adjustable high pressure regulators, automatic changeover regulators, integral two stage regulators, and propane bottle regulators. Integral twin stage regulators are the most common type of device used in residential propane systems, whereas high pressure regulators are more commonly seen in industrial settings. Propane bottle regulators are found on the containers used for gas barbecues and grills.
Underground tanks require special regulators in order to maintain the effectiveness and safety of the device. Underground regulators are covered by a dome in order to prevent damage from water and surrounding elements, such as dirt. There are specific laws and guidelines that need to be followed when purchasing and installing an underground regulator, and it is best to leave this job to professionals.
Gas regulators are generally made of brass or stainless steel. Stainless steel is a popular choice when dealing with corrosive gases, as the steel is tough and durable enough to resist corrosion. Another perk when using stainless steel regulators is that the purity of gas is better maintained by using this type of regulator.
Proper installation of a gas regulator is a legal requirement in most areas. Given the importance of proper installation and the related safety issues, gas regulators should only be installed by a professional contractor. A licensed plumber or a propane company can be hired to complete an installation.
In order to keep a gas regulator in good working condition, some maintenance and attention to the mechanism must be given. The regulator should be covered to prevent damage from weather, pests, and pets. If the regulator incurs damage it should be replaced immediately. Undamaged gas regulators should be replaced every 15 to 25 years.
