  • Electric control valves with jet pump - Samson AG

    Control valves with jet pumps are used in con-trol circuits, especially in district heating sup-ply plants. They assume both the function of a valve for temperature control and that of a circulation pump for the heating water circuit. Configuredas mixing valves, they replace the reducing valve and circulation pump usual-ly installed.

  • Fixing an Excavator Pump That Stalls - Insane Hydraulics

    Virtually all rotary excavators and excavator-based machines use the torque limiter control with override in their pumps, and all of them use an electric proportional reducing valve to pilot the torque controller override. The valve can be either built-in or external to the main pump, but the symptom is always the same - the engine either
