If you have the manual follow it.
If not,isolate boiler from power and water, find a suitable drain cock (lowest point), attach hose to outside,open drain cock.FIT NEW VALVE.
After draining,close drain cock, open filling loop , while another body bleeds rads, keep refilling up to 1 - 1.4 bar. Voila!
