It is necessary to perform and document a risk analysis for each new installation to refute the reproach of negligence in the event of damage. In certain areas, e.g. the separation of the operating or service water network from the public water supply, mixproof shut-off systems are required.

Features Applications Model Document
  • In the basic version, two butterfly valves and one leakage valve are always switched simultaneously. As an extra option, leakage butterfly valves are available with rinsing valve.
  • When both butterfly flaps are closed, the leakage valve is open. If leakage occurs in one of the butterfly valves, e.g. because a foreign body got stuck, the leakage can flow out under atmospheric pressure.
  • Besides the mechanical restricted guidance, a restricted guidance can also be obtained by the control unit. This reduces the switching losses at comparable investment costs.

Wherever reliable separation of media is required and where the increased switching leakage compared to double seat mixproof valves and double seat valves can be com- pensated by the more economical price of the leakage butterfly valve.
