Sea Cocks
Thanks to all posters. As with all the simple questions, there is a range
of answers available. These newsgroups are great. Thanks again "Keith" wrote in message ... I personally don't think they are as good. I replaced three on my boat with Groco seacocks. You are correct about the plug valves working like the valves on titration tubes. You would turn the rubber plug to the position then tighten a screw on the other side which would smush the rubber plug inside the housing, locking it in place. They had to be taken apart annually or so and cleaned and lubed. When you tighten them up, the rubber squeezes up into the openings, especially in the closed position. You don't have any of these problems with ball valve seacocks, which are usually ss on Teflon seats. "Skip Gundlach" wrote in message ink.net... I'm a bit confused, apparently, by semantics or my limited exposure... I hadn't heard of plug valves, so I went looking. What I saw looked about like every ball valve on the insides - except none had easily position-noted lever handles on the outsides. A tapered plug valve led to visions of the kind of valves I used in titration in school - a tapered seat with a matching taper on the handle/valve, and, perhaps, a spring to hold it firmly down? - but that was not the deal. I presume from reading the various chatter on the topic that perhaps it (taper) refers to the threads at the bottom of the valve/thru-hull? In any event, I'm not the least bit sure how they're better than ball valves, as that's what they look like. Those of you familiar with the benefits of the type over a ball, what is their superiority? Thanks. L8R Skip -- "And then again, when you sit at the helm of your little ship on a clear night, and gaze at the countless stars overhead, and realize that you are quite alone on a great, wide sea, it is apt to occur to you that in the general scheme of things you are merely an insignificant speck on the surface of the ocean; and are not nearly so important or as self-sufficient as you thought you were. Which is an exceedingly wholesome thought, and one that may effect a permanent change in your deportment that will be greatly appreciated by your friends."- James S. Pitkin |
