FEATURES
- Valve normally closed
- With flow regulator
- Rapid opening and closing
The VE4000B1 valves are Class A solenoid valves, normally
closed. They may be used as ON/OFF valves in the supply
trains with Natural Gas, Manufactured Gas or GPL, on burners
or combustion plants.
They are provided with M.I. and CE Approval for EN 161.
ADJUSTMENT
For models VE 4000B1 (see fig. 1)
Adjustment to the flow
- Remove the cover from the upper section of the coil.
- Insert a hexagonal Allen key into the central section at the top.
- Turn clockwise to decrease the flow or anti-clockwise to increase it.
- Replace the cover and tighten it.
ATTENTION
- The adjustment must only be carried out by qualified personnel.
- Per la chiusura della valvola è necessario che la tensione ai ter-
minali della bobina sia 0 volt.
- The flow regulator of the VE 4100 valve series is situated in the
lower section.

DESCRIPTION OF HOW THE VALVE OPERATES
Single-stage valves
When the valve receives the signal to open, the pump cuts in and
the magnetic valve closes. The pump transfers the oil from under the
piston to above it, forcing the piston downward, which compresses
the closure return spring with the rod and plate. The valve remains
in the open position while the pump and magnetic valve remain
powered.
When the unit receives the signal to close (or if power supply is cut
off) the pump shuts down, the magnetic valve opens decompressing
the chamber above the piston. The plate is closed both by the return
spring and by gas pressure. The flow rate for this valve is calculated
to ensure full closure in less than 0.6 seconds.
This type of valve cannot regulate the gas flow rate (closure/
opening).
