Double gland cock

Double gland cock

Double gland cock

(OP)
Dear all,

I need your help. I have googled for hours but cannot find this type of valve: "double gland" type. Probably it is known by different name, but if anyone knows how does this valve look like, please help.

Thanks very much

Aida

RE: Double gland cock

Could this be a translation problem from "Twin-Seal", which is a Cameron brand?

RE: Double gland cock

is it used for the blow-off cock similar to a plug type of valve?
per name of "double gland", I guess that there are two glands for two valve packings design.

RE: Double gland cock

Hi mk3223,
I doubt it, although I am not native born English speaking. 'Twin' is in technical language usually used for two separate items in series, or two items doing the same thing. Not as here doing two separate things, sealing two different openings.

Dear mk3223

I thought that's the one, but maybe there's other design that fits the criteria of double gland.

Mr gerharld

Thanks for your input. Yes, probably the sealing is in series, meaning if one gland leaks, the valve still has the other seal, you know, like that below valves. Have you any picture of this valve? I googled and cannot find one.
