Product description

For the largest industrial vacuum installations, the Eurovac 0VRL9000 4" NPT Vacuum Relief Valve provides the ultimate in equipment protection. This valve is designed for ultra-high-volume airflow systems where traditional relief valves would be undersized. Featuring a large 4" NPT threaded connection, it is capable of venting immense quantities of air to prevent vacuum-induced damage in massive central vacuum networks or material conveying systems. The 0VRL9000 is engineered to respond to specific vacuum limits, opening instantly to prevent the blower from operating in a "dead-head" condition which can lead to rapid thermal expansion and catastrophic internal failure. Built with industrial-grade materials to withstand high-velocity air movement and abrasive dust, this relief valve is a necessary safety component for any facility operating large-scale, high-horsepower regenerative blower systems.

Product highlights
