CNG cylinder valves VM05 HD

CNG cylinder valves VM05 HD

CNG cylinder automatic valve type HD


CNG automatic cylinder valves VM05 HD have been developed in particular for heavy-duty applications, and are homologated in accordance with the European Regulations ECE R110 and R10 and in compliance with the ISO15500 standards.

Valve VM05 HD is provided with manual tap, excess flow valve and solenoid valve, and is equipped both with separeted safety devices (thermofuse T-PRD and burst disc). It can be produced with or without ventilation system.

VM05 HD is manufactured with bigger internal passages and can have bigger external connections, compared with VM05 Automatic, allowing a bigger gas flow.
