Integrated Pressure Bypass Valve IBP


The IBP is a valve that closes the bypass channel of the cooler. When the pressure exceeds a certain value in the cooling the IBP opens the bypass channel and allows a part of the fl uid to bypass the element.

Technical Details

  • Low pressure drop
  • Works in any position
  • Maintenance-free
  • Max. working pressure: 16 bar

IBP version           Available opening pressure

IBP2                                             2 bar
IBP3                                             3 bar
IBP4                                             4 bar
IBP6                                             6 bar

Integrated Temperature Bypass Valve IBT


The IBT leaves the bypass channel open so that a part of the fl uid bypasses the cooling element. Only when the fluid temperature reaches the required value, the IBT closes the bypass channel and the fluid is cooled down. So, a too low temperature of the fluid can be avoided i. e. at cold starts.

Technical Details

  • Fixed setting temperature value
  • Low pressure drop
  • Works in any position
  • Maintenance-free
