Hose burst valve
Hose burst valve
(OP)
Hi guys,
I have a heavy duty double acting hydraulic cylinder operating at 230 l/min max flow rate and need to select a suitable hose burst valve for its ports. I cannot find a valve with such high flow capacity and suppose I should look for another solution. Has anybody encountered such design problem before?

RE: Hose burst valve
Do you need a hose burst valve or can you live with an over centre valve?
Also, where you reference capacity, although the valves may not state the flow you require, they may still work, but with a higher delta P.
Do you know what max pressure drop you can accept through the valve?

You can use an over centre valve to do what you want, see attached PDF. An over centre valve is counter balance valve with a pilot port to open the valve.
10 BAR pressure drop @ 250 LPM is a big ask and will drive you towards a big valve.
The valve needs to be located at the cylinder ports.
