Old style shutoff valves...

Looking to remove an old gas cooktop and replace with a gas range.

The shut-off valve has no handle on it, just a square "bolt-head".

Are these still good to use or do they need to be replaced?

If it needs replacing, I would not do it myself, but if I keep it, then I would do the removal and installation of appliances myself.

I assume to close the valve I would just turn the square 1/4 turn clockwise? Then replace flex-hose (hoping that the connector kit has the needed addaptors for this fitting).

Here is a picture of the valve:



I will also remove a gas wall oven. It has the same type of valve and here is a picture of that one:

This one will be removed and not replaced, since we are getting a range in place of the cooktop.
So, here I would just close it with a 1/4 turn and then simply remove the hose. Is the valve in shut position considered enough of an end cap or does it need an aditional cap?

Thankful for any input.

 

The old valve is likely just fine. And yes, you need to cap any abandoned line.

 

Just need a good old fashion crescent wrench to operate!

 

If working in the area I'd be tempted to replace those shutoffs with modern quarter turn ball valves. In an emergency it's nice to have a valve with a handle you can just reach down and close without having to find the key or a wrench.

 

Thanks for the replies!

I looked into these valves a bit more. It seems they need to be "re-greased" every 5 or 10 years? I really doubt that this has been done in my house and I also don't want to regrease them in 5 years.

I guess the square knob is turned 1/4 turn, but there is an allen wrench hole on the other side, that unlocks it for turning. Seems dicey. But nevermind.

These will be replaced! I also realized we have the same valve on our gas tumble dryer downstairs, so someone could come and update all three!

I will have a professional do this!
