I've been looking at spring return valves i.e. with a dead man's handle which would be great in terms of simplicity - could just have a pin to hold back the handle and release when desired, however I have no idea how quickly they would close. Does anyone have any experience with these valves and...
Hi all,
Thanks very much for your responses. Definitely some things to look at.
- With a check valve, would closure time not be dependent on flow rate? I require the valve to be as a repeatable between tests as possible as we will be testing a variety of flow rates.
- I have been wondering...
Cost shouldn't be an issue. Should have mentioned that this will be with a pretty substantial flow rate of 3L/s if that makes much difference.
Our main enemy is time so an off the shelf solution would be fantastic.
Hi all,
I'm currently looking to design a rig capable of recreating water hammer I.e. The pressure pulse created when a shut off valve is closed rapidly which then propagates upstream of the valve.
I therefore require a very fast acting valve (aiming for 20ms) for a 1.5" dia pipe. What are the...
