This 40,000 PSI footgun allows the operator to control the flow of water without using their hands. The footpedal trigger has a large area for ease of operation. It uses a spring to open the valve to switch to dump position when not engaged, for safety. The GD Energy Products 40,000 PSI footvalve has a 60 second quick-change cartridge to reduce time in the field for repair.


  • 40,000 PSI (2750 Bar)
  • The inlet and discharge are standard 9/16” HP female ports
  • The dump tube has a standard ½”NPT female thread to direct low pressure dump water to tank or collection pond

Design Advantages

  • The base of the footvalve is sturdy to prevent the valve from moving during operation
  • The increased surface area of the footpedal allows for more contact between the operator and the tool
  • The footguard on the pedal covers the valve area to protect the operator from potential hazards
  • The spring loaded cartridge will return to the dump position (low pressure) when the foot is removed from the engaged position for safety
