The VR-801 Vacuum Relief Valve is designed to protect hot water supply systems and pressure vessels against negative pressure. Installed on the cold water supply line, the Cash Acme VR-801 closes tightly under pressure and opens at a 1 in. mercury vacuum. Atmosphere admitted to the system breaks the vacuum, preventing collapse of the storage tank.
