Description

This breather valve is a direct equivalent of the Civacon NV3000E. It seals the vapour space in transport tank compartments and regulates pressure within specified limits by balancing pressure and vacuum. It operates as both a breather and a safety valve and must be mounted on the compartment inspection hatch of a road tanker, tank trailer or semitrailer.

The valve complies with GOST 25560-82, EN 12266-1:2003 Industrial valves, and Customs Union Technical Regulation TR CU 010/2011 on machinery and equipment safety.

Advantages

Full compatibilityA direct equivalent of the Civacon NV3000E valve, allowing easy replacement without design changes
Dual-purpose operationCombines pressure equalisation with safety relief against excess pressure and vacuum: one valve performs two functions
Proven materialsAn AK12 aluminium-alloy body provides corrosion resistance and low weight. Viton seals resist aggressive vapours across a wide temperature range
