DIAL PRESSURE GAUGE The dial pressure gauges are specially conceived for the measurement of low pressures ranging from 0 – 25 mbar to 0 – 600 mbar, according to EN 837-3. They are suitable to be used on natural gas combustion systems and to measure pressure of non-corrosive fluids at the gaseous state. 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. Ambient temperature from -10 °C to + 60 °C Indicating accuracy +/- 1,6% V.F.S. Fluid max. Temperature +60 °C Overpressure not allowed Thermal drift with respect to a temperature of 20°C +0,5% every 10 °C temperature rise - 0,5% every 10 °C temperature drop Enclosure IP 32 according to IEC 529 N.B. The max. operating pressure must not exceed 75% of the range bottom value.

TWO-WAY MANUAL PRESSURE COCK WITH BLEED-OFF Operating: 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. Body press-forged nickel-plated brass Sealing perbuna NBR Fluid gas, air Temperature from -10 °C to + 70 °C Diameter Max. pressure [bar] Approval 1/4" 5 DIN DVGW 3/8" 5 DIN DVGW 1/2" 5 DIN DVGW Diameter A B C 1/4" 23 29 54 3/8"...
