Leaking Pump Valves
As a heating engineer of 40 years experience I can assure you that this type of ball valve is false economy,leaking around the screw head after turning them on /off (which may be some considerable time after instillation but the first time they are needed ) is common place .Do yourself a favour and pay the extra for the gate type, Never had eny bother with them at all.

water pump valve
These valves leak from the grub screw and let in air to the central heating system. The are also very difficult to fit without leaking from the main nut. I am now removing mine to fit better quality. They are very cheap in price so its possibly to be expected. Buy cheap buy twice and all that

Poor pump valve
As per previous posts I've just had a leak from the valve when isolating the pump, and the valve has only be installed for two weeks. It only leaked a small amount and soon stopped, but that doesn't bode well for the future.
And even worse, when turning the valve with a wide bladed screwdriver, one lug of the screw sheared off.
I'm replacing them with a pair of pegler valves.
