EQUIPPED CABINETS
Chuchu Decayeux offers a wide range of cabinets which match all types of gas installations, distributed by network, for all network connections to buildings. Cabinets enable to shut-off the gas (shut-off), reduce pressure from network (regulation) and ensure metering in m3
(metering). There are several selection criteria: the cabinet main function (shut-off, shut-off/regulation, shut-off/regulation/metering, shut-off/metering), inlet and outlet piping (copper, steel or PE), cabinet external dimensions, inlet maximal use pressure (from 21 mbar and 4 bar) and outlet maximal use pressure (from 21 to 300 mbar).
Bases are always optional

Much more than a simple ball valve, Vigigaz is an innovative
concept dedicated to the safety of people and
possessions. Vigigaz can be installed in all types of gas
installations.
The VIGIGAZ concept: the gas supply is automatically closed when the slightest smoke, carbon monoxide or gas leak is detected
