Econex VSB Series User manual

Gas safety solenoid shut-off valve series VSB and VSA, ap-
proved according to the norm EN 161 with product iden-
tication and manufactured according to regulation EU
2016/426, are suitable for the automatic control of gases
belonging to the rst, second and third family.
On request there are versions for biogas and air. These val-
ves, normally closed for continuous and cyclic operation,
open by powering the coil and close quickly when there is
no tension.

Installation, adjustment and maintenance of the valve must be carried out exclusively by skilled and authorized service
technicians
1. Before electric wiring, check that the main voltage matches with the power supply voltage stated on the product label.
2. Disconnect power before wiring.
3. By wiring connector, use terminals and cables as reported in the Instruction leaet in the package.
4. Connect the power supply to terminals 1 and 2 and the ground wire to terminal .
5. Using energy saving Green connector with 12 and 24 Vdc comply with polarity.
1. Make sure that all operating data indicated on the safety shut-off valve label correspond to those of the system.
2. Before installing the safety shut-off valve, quit the gas supply and make sure that the pipeline is free from impurities. The pipeline
must be vibration-free.
3. The ow direction indicated by the arrow on the valve body must be respected, facing towards the user appliance. The safety valve
can be installed either horizontally or vertically, provided that the coil is not turned downwards.
4. When installing the safety shut-off valve in pipework do not use the coil as a lever, but use the correct wrench.
5. The sealing material must be applied to the external thread of the pipeline only and not to the internal thread of the safety shut-
off valve.
ADJUSTMENT OF FLOW RATE - OPENING TIME AND RAPID STROKE
1. Coil fastening nut
2. Flow rate adjustment
Unscrew the nut and spin the internal screw clockwise to reduce
and counter clockwise to increase the ow rate.
All the reported data are subject to be changed without notice. from 180911

WIRING INSTRUCTIONS
INSTALLATION AND OPERATING INSTRUCTIONS
1. Flow rate adjustment. Loosen screw A and rotate cylinder
B to the desired position. Tighten screw A to x the position.
2. Opening time adjustment. Turn screw C clockwise to
reduce the opening time or turn counter clockwise to increa-
se values.
3. Rapid stroke adjustment.
