Venting / Draining Ball Valves
The Vexve venting/draining ball valve (type NAVAL) has been specially designed for systems,
that require venting or draining for safety reasons or for maintenance and repair work.
Liquids or impurities e.g. can be drained from the pipe via the drain connection.
Air present in the system, on the other hand, can be conveniently drained via the venting ball valve.
The combined shut-off, venting and draining function in just one ball valve minimizes downtimes and costs and maximizes operational safety.
Vexve venting/draining ball valves can be used in a wide range of industrial sectors, including district heating and district cooling networks and,
thanks to their versatility and reliability, help to optimize operational processes and compliance with stringent safety and environmental standards.
