  • Halkey-Robert Pressure Relief Valve

    Q:

    I bought this to replace the PV on an old (pre-2000) Hyside IK. The dimensions all seemed to match, but the threads on the old valve are much coarser than the threads on this. Does the boot for this have threads to match? Should I get the boot and do a donut patch, or is there an easier way to go?

      A:

      Pete, the threads on the valve and on the boot, item # 38508.01, match. I'm not aware of how the old valve was installed in your boat. You could glue in the boot and use the valve. Or, you could do a doughnut patch and use the Leafield A6 PR Valve, # 38532.01. Here's a video on how to do a doughnut patch - http://www.nrs.com/learn/how-to-replace-a-raft-valve.asp - Let us know if we can help, 800.635.5202 or service@nrs.com.

    Q:

    My PR valve in my old NRS Sprite seems to release air early. I have cleaned it. The valve seems to be in ok condition. Is it possible the spring inside is just too soft? Can I order just the spring?

      I have this same trouble in an older raft too.
       I searched high and low extensively and was unable to find a matching spring with the same measurements, strength, etc. Or a replacement valve for that matter.
      Until you find a replacement, this is what I did....
        
      , VERY carefully remove the retaining disk on the bottom side of the valve. The guts are spring loaded so Don't lose any parts.the gasket and parts. I used a light coating of WD-40 because it was all I had.
      * Carefully remove the valve from the boat.
      * Next
      * Remember the order of each part removed AND its orientation. 
      * Carefully remove each part then clean the inside of the valve and gasket. I used a paper towel then cotton swabs with rubbing alcohol.
      * Recondition
      Now for the tricky part. The main spring inside. * Get a ruler
      * Stand up the spring on the table
      * Measure the height of the spring. Write it down.
      * Use your hands and Carefully stretch the spring a little bit at a time
      * Take care that you don’t mangle the ends of the spring as their size and angle will matter later
      * Your target is an additional Half the springs height and a little more is ok.  Too much and the spring will not fit back inside the valve.
      *  
      * Now
       
       There should only be maybe 3 or 5 parts inside.
      If all else fails, you can get a PVC plug from a hardware store. The floor won't relieve itself but it won't leak either
       
      I had to do all this in the field. And it worked great. The pressure was not like new but almost
      Good luck to you

      I had continual problems with my pressure relief valve............ my solution was to patch over the valve and regulate the floor pressure myself............. I have not had a problem since then.

      The valve comes as a complete unit. We don't have just the spring.

      I recently experienced this problem, and thought, like you that grit might
      be the problem. I finally bought a new pr valve and am completely
      satisfied.
      Happy boating!

      A:

      Hi
      I don't think you can take it apart without damaging the valve. I would
      suggest just replacing the entire valve. Use a plumbers deep socket wrench
      not the wrench they sell form NRS.

    do they make a plug so I can take the relief valve out

      A:

      Bob, Halkey-Roberts doesn't make such a plug. You could probably take one of the PR valves and fill it with epoxy.

      A:

      Mine was so corroded (or glued in) that I ended up busting it out. Chances
      are you will want to replace everything so busting out works well.

      A:

      Specifically made for plugging a raft floor? None that I'm aware of.
       
       However, the hardware store has thousands of them. I prefer a white PVC threaded end plug. White is easier to find if dropped.
      It may be possible to over tighten this plug. The pressure relief valve is a much higher quality than a PVC cap. 
      I have included a photo of what I’m talking about. It has been a while since switching out my PRV so I am unsure of the exact size you need.
       
       I believe it is 5/8” coarse thread or could be 3/4"…. check and make sure your valve is a course thread. Oh, and teflon tape helpd

      Yes. I had a set of long sockets for plumbing. One of the sockets fit the
      valve.

      Brian, it has shoulders on it like a bolt head.

      A:

      Specifically, not that i'm aware of. But a big trusty crescent wrench works great. In a pinch, while channel lock pliers are not preferred, they will do the job.
      Righty tighty, lefty loosey.
      Take note... Mine was very tough to get moving. So i used the biggest wrench i had, a 12 inch adjustable wrench. This gave me an excellent grab on the unit and i could apply much more force gradually or in tiny amounts until it started to move. I also found it much easier with the floor inflated and topped off. Once the valve started to move, i then opened the inflation valve.
      There were many more steps that i used than these but i was being very careful.

    Q:

    This appears to be the pressure relief valve in this older model of white water kayak I have.

    What are the dimensions? Both for the screw in base, and for the top section of the valve? I would just like to compare before purchasing this item.
