Jump Jet Pulsation Control Valve

The Jump Jet Check Valve is used for a pulsation system. This valve deliberately causes the pump to cavitate which makes the hose "jump". This thrust helps nozzles get around bends, go up laterals, or can help nozzles to get unstuck. The jump jet should only be used intermittently and only with the jetting machine running at 1500 PSI idle. 

On 4018 jetting units, the jump jet check valve mounts to the control panel stand, but on 25PMG+ jetters it mounts to the pump head. This valve is rated for 6000 PSI maximum output.
