VM01 light are homologated in accordance with the European Regulation ECE R110 and in compliance with the ISO15500 standards.

Manual Unvented Light Valves have been developed with the aim to target very price sensitive markets.
This version is equipped with manual tap and can be provided with excess flow valve and integrated safety devices (thermo fuse T-PRD + burst disc).

VM01 light is also available in "ARM" version with external threading 1/2 gas, and in EXTRA version, having bigger flow and internal threading M14x1.
