COMBINED GAS VALVE (monobloc) DUNGS
(GASMULTIBLOC) mod. MD-ZRDLE 415 B01 S22
(1"1/2) / MB-ZRDLE 420 B01 S22 (2")
N° 0002910580
Rev. 25/01/00
TECHNICAL DATA
Max working pressure 360 mbar (36 kPa)
Exit pressure (Pa):
MB....S20/S22 = 4÷32 mbar
MB....S50/S52 = 20÷50 mbar
Valves of the class A, group 2 (DIN STANDARD EN 161) suitable for gas belonging to the families 1-2-3.
D.C. coils, noise incidence (solenoid valve against radio noises).
Possibility to exclude the pressure regulator for the use of gaseous LPG (tighten completely, sign +, the
pressure regulator screw). Closing time of the valves 1 and 2 within one second from electric supply interception.
Temperature from -15°C to +70°C, for gaseous L.P.G. systems do not use at temperatures below zero centigrade.
The L.P.G. can condense and, in the liquid state, it would damage sealings and membranes.
Voltage and frequency: AC 50/60Hz, 230V -10% + 15%
Connection time:
100%
Electric protection:
IP54
Assembly position:
coil in vertical or horizontal position; possibility to employ the tightness check for
valves mod. VPS 504.
