Pre-insulated valve for district heating systems

V-Flex is a tailor-made pre-insulated valve for district heating systems. V-Flex provides greater control over heat networks.  Isolate entire networks, individual streets or properties therefore making network maintenance and extensions much easier.

Efficient and easy to use

V-Flex delivers zonal control and can be fusion welded directly to the main network. This allows operators to efficiently control and service PB networks.

The valve innovation includes a key-operated steel ball valve inside a polyethylene casing, insulated by PUR foam, and incorporates PB tails for a fully welded connection to a Polybutene pipe network.

The valves can be specified for single or twin pipe applications.   Chambers of different sizes to accommodate depth variation are available. Each chamber provides easy access to the valve and includes a lockable lid as an option.
