In a customer's vehicle, how should cylinders be positioned concerning the pressure relief valve?

The positioning of cylinders in a customer's vehicle is crucial for safety and functionality. When the pressure relief valve is in communication with the vapor space of the cylinder, it ensures that any buildup of pressure can be released effectively. This is important because the pressure relief valve is designed to prevent the cylinder from reaching dangerously high pressures that could lead to failure or explosion. By allowing the relief valve to remain in contact with the vapor space, any excess pressure can be vented safely to the atmosphere without compromising the integrity of the cylinder.

Ensuring that the valve is appropriately positioned allows for the safe operation of the LP-gas system within the vehicle. This placement is in alignment with safety standards and regulations governing the handling of LP-gas. Consequently, positioning the valve in a way that prevents it from being blocked or restricted by liquid LP-gas enhances safety measures during operation.
