The following is a description of the quick couplers we install on the back of our machines to control the grooming drags. We have heard some users are having a hard time connecting the hoses from their drags into these couplers. The female side has a open/close valve (pictured). It is possible if the valve is open while the engine is operating, and then moved to the close position, pressure could be trapped between the valve and the end of the coupler. This pressure would make it difficult to engage the male end. Remember to close the valves prior to disconnecting the drag hoses. Also make sure the snap covers are working properly.
- ZERO PRESSURE Connection Coupler – Pressures to 2500 PSI
- Connect or Disconnect at “Zero Pressure”, even with pressurized lines
- Positively locks the valves in the open position
- Accepts any male tip that meets the industry standard (Pioneer 8010)
- Color coded levers identify raise and lower lines
- Easily connect or disconnect with one hand (clamp mounted)
- Eliminates spillage and spraying with no back aflow checking
Open position locks open the valves in the body and the tip so they are unaffected by rapid variations in fluid flow. However, inadvertently turning the lever to open without the tip in place will not result in oil flow. Valves will close automatically in case of breakaway.
Closed position shuts off oil flow at the remote outlet, allowing for easy, sprayless, zero-pressure connecting or disconnecting.
