Blew the burst disk on one of my bottles recently, wasn't in the robot the prv would have gone way before, so need a new burst disk if anyone knows where to get them ? Wouldn't want to run the robot without the prv though.
yeah thats mine terry ( they only blow if over filled and heated tho )
do u still have the screw terry or did i take that back as i lost it lol
but back to 1000psi prv can we change the rules that we dont need one ( as long as fair play is involved and co2 used )
no john...For the reasons above.
I changed over a few lever valves a while ago and set the burst discs aside. Can look at the weekend to see if i can find them.Originally Posted by terry
if andy can't find one, i have one you can have.
they are all different sizes and different fittings
ill pop to barbrough bros in brum
No problems with burkets at all, but I doubt the solenoid is the only factor limiting the pressure. My only problem is 50 Bar components operating at upto 69 bar.
Without knowing the design pressure of the assembly, the materal grades used and relative internal diameters & thicknesses - randomly choosing a test pressure could be dangerous. If you exceed the yield limits of the metals used, they will probably pass hydro test but may fail in service at some later date. But I agree that any valves should be tested if used above their intended design pressure - although I wouldn't want to provide the guarentee in case one did fail. Also I wouldn't test the units to a pressure any higher than is necessary.
Not being picky or arsey but safety is safety. I heard a horror story recently from a visting assessor coming in for a witnessed hydro test, he took a look at the assembly and pointed at the drain plugs we were using. He then went on to tell me how a man lost his life during a pressure test all thanks to a 1/4 BSPT plug that stripped its threads. Could you imagine having to live with that all for the sake of a hydro test?
For your own safety, if the components in the system are rated for less than the relief valve then get them tested.
I thought it was a requirement that all components were rated high enough? Or that your PRV was rated below your weakest component?
as is proven any system with lage buffer tank ie 2kg buffer the presure is about 350 to 400 psi divied that by 14.7 and its no where near 69 barMy only problem is 50 Bar components operating at upto 69 bar
Gasbot.
Untill 2010 I had the official paperwork designating me as a certified pressure technician, allowed to write and authorise test reports.
In my opinion a Burkert is overdesigned for the job it does. Given a stronger solenoid, those valves are fine with working pressures over 1200 psi.
But you don't have to believe me.
In any case, we're building Combat Machines. Not bumpercars or animated barbiedolls.
