Normally closed valve. Manual opening

when energized.

The VG series safety solenoid valves

are suitable for the control of gaseous

fluids in gas consuming appliances

according to international standards.

The VG series safety solenoid valves

meet the class A specification

according EN 161.

The VG series safety solenoid valves

coverawiderangeofpipesize

connections.

From 3/8” (DN 10) upto and including

3” (DN 80).

The VG series safety solenoid valves

are available with treaded connection

from 3/8” (DN 10) upto and including 3”

(DN 80).

The VG series safety solenoid valves

areavailablewith2

1/2” (DN 65) and

3” (DN 80) flanged connection.

The VG series safety solenoid valves

have 2 auxiliary pressure stops with

Rp1/4” threaded connection both at the

inlet pressure side of the valve.

The VG series safety solenoid valves

have an inlet screen for protecting the

valve against ingress of dirt.
