Gas cylinder regulators can be referred to as devices connected to the delivery valve of a cylinder. These have an inlet connection for the cylinder and an outlet connection for the connected appliance. Regulators are used for controlling the gas flow from the cylinder to appliances like gas stoves. The regulator brings the internal maximum pressure of a cylinder to lower pressure for output delivery. They function as a protective mechanism to restrict gas flow in case of leakage from faulty gas tubes or cylinders. Regulators are equipped with control knobs to maintain the output delivery of gas at the desired pressure. Also, many regulators may have valves for pressure relief to protect from over-pressurisation. Apart from safety mechanisms, you have indicator functions in regulators. They have built-in gauges that let you detect low gas supply. You can get regulators for cooking cylinders in household and industrial cylinders. Shopsy has a wide range of regulators for gas cylinders. You can find regulators in various colours online. Apart from colour variations, you can get them in single or combo packs. These packs have hose pipes and gas stove lighters in addition to regulators.
