Line & Service Regulators Line and service regulators are typically installed before the equipment that already has an appliance regulator. Mainly used in domestic, commercial and industrial applications, they have many options such as internal relief valve, indoor ventless, etc. These are the most common regulators used on all types of non-corrosive gases.
