How do pressure valves work?
How do pressure valves work?
(OP)
please provide any internet sites or articles about how does any pressure regulating device work,whether it is pressure reducing or sustaining valves,
i need the theory behind it as well as the actual physical things and motion that makes it work, how does it sustain the pressure or reduce it.
please also any sites about the terminology of valves ,, all the common names for all valves types ,it's realy confusing
please guys ,any help would be very appreciated
thanks alot

Will give you an idea how this works in a sliding gate seat valve.

When the presseure gauge reading goes more than the desired level the assistant closes the valve regulating the flow.When the reading goes down the assistant opens the valve to allow more air into the vessel which raises the pressure inside.This cycle may repeat any number of times.So instead of having a man to monitor the gauge and act,a small device is installed in place of the throttling valve which measures and compares the pressure with the desired"set" pressure and acts accordinglly maintaining the pressure.So this is the pressure regulating valve. Any more doubts?

now, do i need a pressure sustaining valve downstream of that tank (peak ponit) ,and why if i need one ? isn't the tank enough to protect the pipe ?
RE: How do pressure valves work?
i am unable to configure your exact requirement.you want to protect -the tank or the pipe line.If it is the tank, better try a safety valve with sufficient capacity .If it is for the pipe, connect a surge tank of required volume to minimise if not eliminate the pressure surges. What exactly you mean by the one way tank- is it a closed vessel with only one inle/outlet.If that is what you mean then this should protect your pipe line.
RE: How do pressure valves work?
the tank isn't pressurised, so it got no compressed air,
i hope it's clear now.
so do i need that sustaining valve downstream
RE: How do pressure valves work?
please make out a sketch of your piping layout indicating the inlet and outlet positions and the tank.If it not possible to include the sketch in this forum kindly contact k_ramdas41@hotmail.com along with the sketch.On understanding your piping a better solution might result.
