Mbvef Gas Valve Assembly; Skp75 - elco VECTRON GL 05.700 DUO PLUS Betriebsanleitung

Overview
MBVEF compact gas valve assembly
SKP 75 regulator
The MBVEF compact gas valve
assembly is a combination of filter, gas
/ air regulator, valves and pressure
switches:
fine 0.8 mm mesh filter
–
GWA2 pressure switch
–
servo pressure regulator unit with
–
adjustable V ratio, correction of zero
value N and furnace pressure
connection
V1 and V2 fast-opening and closing
–
magnetic valves
Input pressure pe: 20-100 mbar
Voltage, frequency: 230 V, 50-60 Hz.

The SKP regulator combined with a
VGG/F valve provides a constant
gas/air ratio with adjustable V ratio,
correction of zero value N and furnace
pressure connection.
Voltage, frequency: 230 V/ 50-60 Hz
