Advice on water pressure reducing valve please ...

Why should they not be used as restrictor valves?
Why do some manufacturers supply restrictors with ball-valves(Neva)?also Torbec-both good quality,have you an explanation to support your IMO.this is an open forum if you state an opinion it can be challenged.

All ball valves come with a restrictor, it's just that the Torbeck type fit inside the inlet. Other ball valves have either a red orifice (low pressure ) or white for mains /high pressure .This is fitted against the washer inside the main body.
The purpose of a restrictor is to allow the float(ball) of the valve to close off the water supply . For example ,if you convert a house from gravity fed to mains supply then the red orifice needs changing as the float will not overcome the force of water through the low pressure orifice and will run constantly.It will not stop water hammer.

The orifice reduction in either red or white is a restrictor it reduces the diameter of the hole prior to the water hitting the diaphragm.So what is your point,by resticting the water in ,the valve operates to its full capacity.

The Torbeck valve is a combination of an equilibrium valve and a diaphragm valve. Once open, the valve is balanced and stabilised by equal water pressure on both sides. This stops it "jumping" which is the cause of water hammer in other systems.The Torbeck valve is a combination of an equilibrium valve and a diaphragm valve.

The TORBECK plastic equilibrium float valve fits bottom inlet toilet cisterns and header tanks.Reduces water hammer and flushing noises

You might need to consider fitting one of these Water Shock Arrestors (code 93058) to redue the "clunking noise":

This would be a solution and probably the best one ,the whole system would then be covered.
