Knife Type Gate Valves

Has anyone ever seen one of these? I wonder if they have metallic components?

Tangster? Anyone? Beuler? Beuler? Beuler?

 

Yes Larry those I think have a metal stem there are some gates that are all plastic You need some ? I may have several around the shop or my son in Richmond will have plenty if needed ? The stem is either Brass or S.S on that type .. Its not acid/corrosive grade S.S either ): so t will not do for saltwater

 

ROFL Oh the throwbacks to when I'd skip school seemed like that movie was always on

 

they look like those (septic) holding tank valves for rv's...lol
just my opinion

 

I need one single 1", but I can get them ok, thanks. I wanted a slimmer one like this knife-type for my return. The way my return is fashioned, I'd have to remake the whole thing to fit a PVC gate valve, whereas I could have simpy removed an inch or so of pipe and fit that knife-type in, without all the trouble. But I guess thems the breaks.

 

You can check to see if the stem are acid or corrosive proof . To be sure ? and Brass is totally out stems have to be Titanium or 316 S.S or practice . In a tight spot I have trimmed pipe and the hub of the fitting or valve to get them in the spot
