Control value for heater unit

Looking to get a control value for the heater unit - picture below. Mine has decided to begin to leak over the exhaust Needs to obviously not leak but also actually regulate between hot and cold air - on the off chance that we have some hot weather this summer. Cheers James

Is this what you need?

Yeah that looks like it - not too expensive either. Will see if I can sorce a working secondhand one over the next couple of days - if not will go with that one - cheers Smudge thanks for posting
