It is used as a water vapour flow regulator. The regulation is provided by a disc butterfly valve driven by an electromechanical actuator.
The actuator uses the principle of combining in one mechanism the functions of relatively slow-acting precise automatic or manual control of the gate by means of MEOF and the function of fast-acting emergency control of the gate by means of spring actuator without the use of oil.
Place of installation: pipelines of production steam extraction.
Installation requirements: BZR is designed for installation in closed premises with ambient temperature up to +50 °C on horizontal pipeline sections in upward position. Connection to the pipeline: under welding.
