Remote seacock operation

as title.... Have a seacock in a difficult to access place, no way of having a hatch above, so long levers /rods are out, to save craling through a hole am keen to find a mechanised and or electric remote way of operating.....

Its in the bilges so would need to be water proof solution (if electric).....anyone able to point me in the direction of a solution /piece of kit to suit?

Many thanks

How about a local lever actuated by a pull cable? Would only work one way unless the cable was stiff enough to push it the other way though.

Hmmm. I do remember reading about such a thing a little while back. If I can remember the details I'll let you know.

We had one the same on the fisheries rib but that was to meet the coding in case of engine 'room' fire. That certainly pulled closed but I can't remember if if was remote opening.

Be aware if coded an electrical one might need a mechanical back up for closing too.

Have you tried somewhere like RS?

A few options that I have used over the years:

Valvestock - Actuated Products

SAFI - Thermoplastic Valve Solutions

Worcester Controls

Essential to have a closed / open indicator on the console (the electric actuators have limit switches fitted for this purpose).

Cheers

Chris

To meet the coding does it need to fail closed?
How much space have you got where it needs to be fitted?

We fit many actuated valves from 1/2" to over 6' (yup that's feet), even the "cheap" 1/2" ones cost the thick end of a grand. Knowing the failure rate, I wouldn't use one on my boat as a seacock An 1/2", 1/4 turn actuated ball valve is still a bulky thing to get under a deck. I'd be looking at fitting an access hatch in the deck & having a "proper" manual valve.
I've not come across any 1/4 turn ball valves that fail closed. They usually drive open & drive closed. If they fail, they will fail in whatever state they were when the power went off.

Cheers all, some good suggestions there, will follow up leads on Tuesday....and report back.

Chewy - There is a lot of space, but (and in partial response to PD) there is no possible way of getting a hatch above (definately - we have looked at every possible way)..... Currently you can climb /upper body through a side hatch into the bilge and operate the seacock, but not ideal /would like to do it from the helms position.....BTW it is /would be just deep enough to lie in down in there, once you've made it under the prop shaft

I have seen some US sites /systems with 'fail shut'......

The other idea I had was (working on the basis that the main concern /risk etc is failure of the joint /pipe where the flexi pipe joins onto the sea cock body - if the skin fitting failed then there would be nothing you can do in any case) to have a solid pipe which mechanically screws to the seacock (so little /no risk of failure) and which then remains solid until it gets to an easily accesible /much higher point (alongside the engine above deck level) where it could then have a valve inline (if required) before going to the flexi-pipe and on to the filter..... But working on the basis that the sponsons will always be above water level, then the water inside the pipe should never be higher than the solid pipe......would still have the manual op seacock at low level /as is.....and no worries about leaving it on a Mooring..... any thoughts?
