Anver vacuum check valves
A full line of leak-proof, one-way vacuum check valves that are designed to optimize vacuum pump performance in a wide range of material handling systems is available from Anver Corp. Anver CheckVac Valves are made from a seamless, one-piece aluminum body and feature a plastic valve element with a specially tempered stainless steel spring and an O-ring seal. Unlike pressure check valves which have a stiffer spring and were designed for compressed-air, this vacuum system check valve provides up to a 4 times better flow rate for optimum performance. Eliminating the major source of flow restriction in most vacuum systems, Anver CheckVac Valves' increased flow rate permits the use of smaller vacuum pumps in many applications. Offering low cracking pressure and a smooth bore, these leak-proof check valves come in 1/4 through 2 in. NPT sizes and are spring loaded to operate in any orientation.
