I need to replace the ball valve in my water tank, does it matter if its high pressure or low pressure valve?

You need to use High Pressure valve if the water is coming from the main water supply and Low Pressure valve if the water coming from another water tank.
If you fit a Low Pressure valve with the water coming from the main supply the valve will not shut of properly because the hole to big.
