The Imtec Quick Dump Rinse (QDR) valve is an air open/close valve. Quality tested to 1.3+ million cycles. While it looks similar to other quick dump valves, it has some important differences. The first is that it utilizes Glyd rings instead of O-rings. Glyd rings do not need to be lubed and reduce the chance of stiction, which is common to O-rings.
Secondly, the valve is attached to the mounting ring via shoulder screws instead of having a large thread that can easily cross thread and make the valve useless. A domed dump door was added to shed any fluid left after a quick dump, improving process performance. The valve is available to mount to PVDF, NPP, or PFA tanks.
Imtec’s years of experience in the industry means that we know what features can save cost and improve efficiency. Looks can be deceiving; trust Imtec to offer you products that work better and last
