470-6119: 3/4" Vacuum Relief Valve

Description: A Vacuum Relief Valve is used to protect a system from the negative pressure caused by a vacuum. It is typically installed in a pipeline or vessel that is subject to vacuum conditions, such as a storage tank or a process vessel. The valve is designed to open automatically when the pressure inside the system drops below a certain level, allowing air or another gas to enter the system and equalize the pressure. Attributes: • Prevent unbalancing of the system or damage to the storage vessel • Prevents the system from collapsing or imploding due to the vacuum • Withstand high-pressure applications Applications: A Vacuum Relief Valve is used to protect tanks from the build-up of excessive pressure or vacuum. This is mostly used in Cat MT3300, MT3700, and MT4400 Truck.
