ANVER’s top selling Miniature Vacuum Relief Valves come in two thread sized – 1/2″ and 3/4″ making them suitable for all vacuum applications where vacuum relief is required. These Miniature Vacuum Relief Valves are adjustable and they can operate in any position. They can keep an electric pump operating at a cool temperature, and/or prevent a load surface from puckering by using excessive vacuum. ANVER recommends using a vacuum gauge to ensure the vacuum level is at the correct setting. • Adjustable cracking level – adjusts from 6″ Hg – 27″ Hg (152mm Hg – 686mm Hg) • Locking jam nut • Optimum flow design for vacuum applications • Spring loaded – operates in any position • Dependable, durable construction • Prevents vacuum pump burn-out by allowing air to enter
