For use of the valve limited to the user involved

The Toptest series, gas valves with pressure outlet, is designed following the entry into force of the Uni CIG 7129 standard of 2008 which requires the use of the gas valve limited exclusively to the user concerned. For this purpose, if necessary, taps with keys, niches and lockers with keys for exclusive use, other similar devices are considered suitable.
 
The range of gas valves belonging to the Toptest series includes different combinations: straight, angled and with meter connection. All models are equipped with a pressure point for testing the system in addition to the closure with a default lock.
 
The pressure outlet must be positioned downstream of the shutter with respect to the flow direction of the system.
The Toptest valves supplied by Enolgas, when equipped with a cap with gasket, are mounted and tested for its tightness, therefore we decline all responsibility for improper use by third parties.
