Gas regulators reduce gas pressure in containers and cylinders, ensuring gas quality and safety. Single-stage and two-stage regulators are common types, with other variations for specific applications. Proper installation and maintenance are crucial, and replacement is necessary every 15 to 25 years.
Gas regulators are devices that are used to reduce the pressure of gases in a container or cylinder. These devices help ensure gas quality and purity, as well as prevent injury and equipment damage. Gas regulators are made for use with specific types of gas, such as propane.
The two main types of gas regulators that help control gas pressure are single-stage and two-stage regulators. The single stage regulator reduces the pressure in one step, while the two stage regulator requires two steps in the pressure reduction process. When choosing a gas regulator, it is vital to understand which phase of the 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 switching regulators, integral two-stage regulators, and propane cylinder regulators. Two stage integral regulators are the most common type of device used in residential propane systems, while high pressure regulators are more commonly seen in industrial settings. Propane bottle regulators are found on containers used for barbecues and gas grills.
Underground tanks require special regulators to maintain the effectiveness and safety of the device. In-ground regulators are domed to prevent damage from water and surrounding elements, such as dirt. There are specific laws and guidelines that must be followed when purchasing and installing an underground regulator, and this job is best left to the professionals.
Gas regulators are usually made from brass or stainless steel. Stainless steel is a popular choice when dealing with corrosive gases, as steel is strong and durable enough to resist corrosion. Another advantage when using stainless steel regulators is that gas purity is better maintained 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 related safety issues, gas regulators should only be installed by a professional contractor. A licensed plumber or propane company can be hired to complete an installation.
To keep a gas regulator in good working order, some maintenance and attention must be paid to the mechanism. The regulator should be covered to prevent damage from the elements, pests and pets. If the regulator is damaged, it must be replaced immediately. Undamaged gas regulators should be replaced every 15 to 25 years.
