Vacuum System Components Vacuum Check Valves Feature Low Cracking Pressure
A line of check valves that were specifically designed for vacuum system applications and eliminate the use of pressure check valves with stiffer springs is available from ANVER Corporation of Hudson, Massachusetts.
ANVER CheckVac™ Valves are designed for all industrial vacuum applications where vacuum loss prevention is required and feature low 0.17 psi cracking pressure with flow rates up to 63 CV. Unlike pressure check valves, these vacuum check valves optimize system performance by not wasting the pump’s power opening stiffer springs; resulting in up to four times better flow.
Allowing the use of smaller vacuum pumps in many applications, ANVER CheckVac™ Valves are made from a leak-free, seamless, one-piece anodized aluminum body with a smooth bore and have a plastic valve element with a specially tempered stainless steel spring and an O-ring seal. Designed to operate in any orientation, they are offered in 1/4” through 2” NPT sizes.
