Pressure reducer with filler

The pressure must be mounted within a reasonable distance from boiler or boilers; the hot water produced by them increases in volume and, consequently, increases the pressure in the making unstable the operation of the pressure reducer. In order to avoid this drawback recommend assemble an expansion vessel in the system between the pressure reducer and the pressure gauge boiler.Gli attacks the reducers are positioned on the two sides of the reducer; both connections measure the output pressure. All our pressure reducers are tested on the dyno and calibrated to 3 bar, unless otherwise indicated.

To change the outlet pressure is sufficient to loosen the nut and turn the black plastic premomolla brass as shown in the sequence below; rotating clockwise the pressure increases, rotating counter-clockwise the outlet pressure is reduced.

The correct pressure adjustment must be made when the system is closed.
