    Hi,

    I might be very wrong but it could be a gate valve (NRV)?
    Something like:

    But I would expect it to have an arrow etched on its surface somewhere.
    If you give it a bit of a clean, maybe you could feel around the surface for any etched markings?

    Also, you may get a much better response if you posed the question in the 'plumbing and central heating' section :)

    Is that one of those dampers to stop the pipes hammering when you turn a tap off?
