Low Pressure Gas Regulators are used to regulate the flow of gas through domestic appliances. They use a spring-loaded "poppet" valve with a thermoplastic or elastomeric seal. The seal is positioned on the valve seat and moves away from it as fluid flows through it. The outlet pressure then generates a force on the spring, which closes the valve. The two forces balance at a predetermined set point.

Depending on the type of gas, there are different types of Low Pressure Gas Regulators available. Some are designed for burning gas while others are non-corrosive. The range of LP Gas Regulators is designed to meet different needs. For example, there are low pressure regulators for water heating, cooking appliances, and even outdoor appliances.

To properly use a Low Pressure Gas Regulator, you must connect the pressure source and regulated pressure lines. If you connect them incorrectly, you can damage the internal components of the regulator. Turning on the supply pressure slowly should be done so as not to shock it. In some designs, full supply pressure can be delivered to the outlet port.

Low Pressure Gas Regulators are useful for reducing the pressure in cylinders or process lines. They reduce the high pressure of a gas and maintain a safe pressure within the delivery system. They do not regulate the flow of the gas but only the pressure at the outlet. Moreover, they are useful for regulating the flow of compressed air and hydrogen.
