The dial pressure gauges are specially conceived for the measurement
of low pressures ranging in mbar, according to
EN 837-3 or high pressure in bar.
They are suitable to be used on natural gas combustion systems
and to measure pressure of non-corrosive fluids at the
They are available with 1/4” – 3/8” – 1/2” radial male connection
and with 63 – 80 and 100 mm dial diameter size.
The standard version is equipped with dual scale in mbar
and in H2O mm.
The manual pressure gauge valve enables, by pushing the button, to check the existing pressure when testing the system.
By releasing the button, the valve automatically closes; the manual pressure gauge returns to 0 setting and to rest position, remaining protected from water hammers, accidental overpressure, etc.
These pressure cocks have the certificate according to norms EN331.
