  • Halkey-Robert Pressure Relief Valve

    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!

      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:

      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

      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:

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

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

      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.

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

    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.
