I believe this is a manual gate valve by MDC vacuum products. I say manual because there are no places that a hose could connect. It came from a working machine, so I am assuming it works. You will be able to return it if it does not suit your needs. It was used on a duoplasmatron if this helps. Please see all pics for details. What you see is what you get. The device plus two (2) O-ring like gaskets. Thanks.
