VACUUM CHECK VALVES PROVIDE 4X BETTER PUMP FLOW RATE
A 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. CheckVac valves are made from a 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 is said to provide up to a 4X better flow rate.
The 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 to 2 in. NPT sizes and are spring loaded to operate in any orientation.
