Increased Productivity

The WALTHER IDHS connects to a hot stab receptacle like any other standard unit. Howewer, it has 2 redundant supply lines attached. The internal valve design ensures that a damaged line will be isolated automatically while the other line takes over and the system stays operationable.

Subsequently, the hot stab can be disconnected and replaced during a scheduled maintenance at any convenient point in time. Even if both lines fail, the system automatically vents the receptical.


  • No production loss due to a collapsing hydraulic hose
  • No emergency intervention required

Improved Operational Safety

The valve design allows further to vent directly at the IDHS location. This eliminates the necessity to vent / depressurize the complete line in case of an emergency shut down requirement. Subsequently actuator evacuation or valve actuation occur much faster than in other systems


  • Increased safety by drastically shorter response time
