CheckVac valves are designed for industrial vacuum applications where vacuum loss prevention is required. The valves feature 0.17 psi cracking pressure with flow rates up to 63 CV. Unlike pressure check valves, they optimize system performance by not wasting pump power opening stiffer springs, resulting in better flow. The valves are made from a seamless, one-piece anodized aluminum body with a smooth bore; they have a plastic valve element with a tempered stainless-steel spring and an O-ring seal and are offered in ¼- through 2-in. NPT sizes.
