Ball valve fine adjustment, Potable water suitable, nickel-plated bright brass, Temp. -15°C to 120°C, Rp 1, DN 25, PN max. 40 bar
Brass ball valves in the standard series with fine adjustment.
Unlike our classic standard ball valves (open-close function), this model features a special stem technology that allows finely modulated opening and closing of the line.
The flow rate can be regulated extremely precisely as a result.
The cock is made of low-lead brass with a bare brass surface on the inside. It is thus safe to use with drinking water. This valve complies with the European standard EN 13828 and the working paper DVGW W 570.
