Rated 3 out of 5Â by JumpingJackFlash Ball Valve v Gate Valve
Just an advisory note to be aware that the advantages of a (full bore) ball valve are that it is 1/4 turn and has low delta P. Disadvantages are difficulty curing spindle gland leaks and valve seats are soft so will not last forever.
Gate valves have metal seats and a "backseat" to allow you to change spindle seal packing if wound tightly anticlockwise.. However, they need excercising oaccasionally and have higher delta P

I bought a cheaper set too as I wasn't sure which to fit. Having looked at then both the Peglar ones look far better quality.

These ball valves are much better than the old gate valve types that seam to always stick and then never really seal well.
Always used these and save yourself future hassle

Smooth operation when in use. Just make sure you line them up so they are easily accessible for testing once fitted.
