Important Notes
Usage for intended purpose
Use TC airline valve VV 10 only for venting hazardous tank containers (TC) of IMO classes 1 and 2.
Use this pressure equipment only within the specified pressure and temperature ratings and check chemical
resistance and suitability for the application in question.
Safety note
The airline valve must only be installed by qualified staff.
Qualified staff are those persons who through adequate training in engineering, the use and application of safety
equipment in accordance with regulations concerning tank containers, and first aid & accident prevention have
achieved a recognised level of competence appropriate to the installation and commissioning of this device.
Danger
The valve is under pressure during operation.
When loosening sealing plugs, corrosive, toxic, flammable or contaminant liquids or gases may escape.
This presents the risk of severe cases of poisoning, severe burns to the whole body or even death.
Do not carry out any installation or maintenance work until it is verified that the tank container has been
depressurized and thoroughly cleaned.
All relevant safety precautions and environmental regulations concerning the handling of hazardous
substances must be observed when cleaning or servicing the equipment.
Sharp edges on internals present a danger of cuts to hands. Always wear industrial gloves for
installation and maintenance work.

Tank container (TC) airline valve VV 10
1 TC airline valve type VV 10
1 Installation and maintenance manual
Description
The airline valve VV 10 is designed for venting hazardous tank containers (TC) of IMO classes 1 and 2. The VV 10
meets the following requirements:
■ Sea transport: IMDG Code: General introduction/GGV Sea
■ Rail transport: RID/GGVE, Annex X
■ Road transport: ADR/GGVS, Annex B 1b as well as the associated
■ TR Technical Directives of the German Federal Ministry of Transport
■ AD Bulletin
For the airline valve VV 10 an Inspection Certificate issued by Lloyd’s Register is available.
Function
The TC airline valve VV 10 is part of the loading and unloading system for hazardous tank containers of IMO
classes 1 and 2. The VV 10 is operated manually by a lever equipped with a sealing device for customs according
to TIR.
Maintenance intervals
The airline valve VV 10 must be inspected and checked every 2.5 years.

Corrosion resistance
When used for its intended purpose the safe functioning of the valve will not be impaired by corrosion.
Sizing
The valve body must not be subjected to sharp increases in pressure. Flanges are designed to withstand dynamic
loading (bending and alternating stress). The dimensional allowances for corrosion reflect the latest state of
technology.
Installation
Danger
After removing the transit protection the valve ball and seals might drop out of the valve body.
This presents the risk of injuries to arms, hands and feet.
For installation place the airline valve in the
container.

Tools
The following tools are required for mounting the valve:
■ Spanner 19 mm A. F. to DIN 3113 B / ISO 3318, 7738
■ Torque spanner 6 - 50 Nm to DIN ISO 6789

Maintenance
Danger
When opening airline valve VV 10 or loosening flanged connections and sealing plugs, corrosive, toxic,
flammable or contaminant liquids or gases may escape. This presents the risk of severe cases of
poisoning, severe burns to the whole body or even death.
Do not carry out maintenance work until it is verified that the tank container has been depressurized
and thoroughly cleaned.
Do not carry out maintenance work unless the airline valve is completely drained and thoroughly
cleaned.
All relevant safety precautions and environmental regulations concerning the handling of hazardous
substances must be observed when cleaning or servicing the equipment.
Sharp edges on internals present a danger of cuts to hands. Always wear industrial gloves for installation
and maintenance work.
Tools
The following tools are required for maintenance work:
■ Key for hexagon socket screws 3 mm A. F. to ISO 2936
■ Spanner 17 mm A. F. to DIN 3113 B / ISO 3318, 7738
■ Spanner 22 mm A. F. to DIN 3113 B / ISO 3318, 7738
■ Torque spanner 6 - 50 Nm to DIN ISO 6789
■ Torque spanner 4 - 12 Nm to DIN ISO 6789
■ Open-end spanner 14 x 17 A. F. to DIN 3110 / ISO 3318
■ Circlip pliers 2.3/220 to DIN ISO 5256 C
