BÖHMER Odorizing Nozzle Exchange Valve (OEV)

The Ball Valve with an Eye for Detail

The odorization nozzle exchange valve (OEV) was developed to simplify injection nozzle maintenance and service. The inspection window makes it possible to inspect the vaporizer without removal.

Die OEV ist a ball valve with integrated inspection window and injection nozzle connector.

The close cooperation of our engineers with the companies “Westnetz” and “innogy” made it possible to manufacture a valve with such features while maintaining a high level of operational reliability, for which all the Böhmer ball valves are known worldwide.

Have you got your eye on your injection nozzles?

During odorization, secondary gas substances and dust form deposits on the vaporization bodies of injection nozzles. In the course of time, the odour substances and deposits form a sticky substance on the surface of the injection nozzle.

The vaporization surfaces of the injection nozzles are minimized and the odour substance can no longer be fully vaporized. Over time, the injection nozzles lose their function and – in extreme cases – can break off under the influence of the media flow and vibrations.

Faulty injection nozzles restrict the odorization processes. Liquid odour substance drops into the gas pipeline and leads to a hardening of valves and fittings. The failure of a valve is expensive. It means high costs for acquisition, replacement and plant down-times.

Inspections: Disruptive and expensive

At present, gas is predominantly odorized at the system outlet. The injection nozzle feeds the odorant directly into the pipeline. In order to inspect an injection nozzle, the complete pipeline usually has to be shut off and the nozzle removed.

This means shutting down the system for the period of work. Under certain circumstances, a service provider has to be contracted to provide the gas supply as an alternative.

With our OEV this changes!

Visible advantages!

Unlike the classical method of installation in the pipeline, with the OEV the injection nozzle is installed directly into the ball valve.

To service the injection nozzle, the valve is shut off and its interior chamber depressurized. The gas flow is fed on via a by-pass pipeline.

The ball opens up the view to the injection nozzle.The inspection window makes it possible to inspect the injection nozzle without removal. To exchange, the injection nozzle is removed from the odour line simply by hand and screwed out of the ball valve.

Thanks to the OEV, these procedures now hardly take any time at all. The valve increases the efficiency of inspection and maintenance work and makes it possible to achieve a significant saving of costs.
