suzuki98 14 Report post Posted March 30, 2007 if I need less pressure for more delicate work would a different orifice work? If so would a larger number over a smaller number orifice be my choice? (ex. 5 orif. vs 3 orif) Share this post Link to post Share on other sites
0 mas3372 14 Report post Posted March 30, 2007 Changing to a larger orifice tip will cut down pressure and for delicate work, user a broader degree tip such as a 40 degree. Also, a dual lance wand works great for adjusting pressure with the same tip. Share this post Link to post Share on other sites

0 Lightning Gene 66 Report post Posted March 30, 2007 Also having a pressure gauge helps you lower the pressure to what you want... Share this post Link to post Share on other sites
0 A and J POWERWASHING 64 Report post Posted March 30, 2007 If you have a ball valve you can turn down the pressure that way too. Share this post Link to post Share on other sites

0 MMI Enterprises 289 Report post Posted March 30, 2007 If you have a ball valve you can turn down the pressure that way too. just a thought..I am under the impression from professional equipment folk that a ball valve on the intake to starve pump can cause problems in long run for pump. yea? nea? Use chart such as found here- http://www.dultmeier.com/pdfs/tech-library/C_Nozzle.pdf ..take pressure your after from top and go down to your machines gpm then on over to the left to the orifice sizing. ps- Dultmeier Sales Technical Library: product literature, specifications, documentation, instructions, charts and diagrams great resource a page earlier on that site Share this post Link to post Share on other sites

0 PWkid 79 Report post Posted April 5, 2007 I have used ball valves for years and no pump problems on this end. I use them daily on my machines one is 9.3 gpm the other is 8.5 gpm. my .02 worth Share this post Link to post Share on other sites
0 One Tough Pressure 580 Report post Posted April 5, 2007 just a thought..I am under the impression from professional equipment folk that a ball valve on the intake to starve pump can cause problems in long run for pump.yea? nea? Why would you want to starve the pump? Not good for any reason. If you need to decrease flow for something, a ball valve can be added to the high pressure side of the pump and back to the tank to bypass excess water. Put in a smaller nozzle and the pressure stay the same. If all you want is to lower pressure and keep the volume a larger nozzle or dual lance wand will handle that real easy.
