A vent limiting device is an important part of an LP gas regulator because it prevents gas from escaping the unit in the event of an explosion. The vent limiting device should be installed at a height where it cannot be damaged by moving furniture or being hit by objects. It should also be installed at a distance of at least three feet from a possible source of ignition within the building, including a mechanical ventilation air intake.

This safety device is typically made of a black plastic material and features a green dot on the side. When the regulator is installed, the diaphragm will move upward as pressure is applied to it. This action will allow a specific flow of fuel to be delivered to the cylinder. The amount of pressure and flow is controlled by a control knob on the regulator. By turning the control knob clockwise, the regulator will release more fuel than when it is turned counterclockwise.

Twin stage anti explode low pressure regulators are designed to reduce high gas pressures in cylinders to safe operating pressures. Selecting the right regulator for your operating system is important to ensure safety and reliability. Regulators measure pressure only, not flow rate, so they are best used with tanks that have a low cylinder pressure.

Two stage regulators help prevent gas delivery system freeze-ups during low-temperature conditions, as the pressure drop in each regulator is evenly distributed between two devices. They also permit the use of single high-pressure lines and multiple low-pressure regulators to optimize LP gas appliance performance.

If you notice a gas leak, first check your regulator for proper function. The valves on regulators should be clean and free of debris. Similarly, the connections on cylinders should be free of oil, grease, and dirt. If they are corroded or cracked, it is best to return it to the manufacturer.
