Thanks for all the help everyone. It is truly appreciated. Mark

Hello Again, More information: What I am doing is fatigue testing a valve. This is being accomplished by moving the valve in a fluid as opposed to moving the fluid through a stationary valve. On the downstroke of the valve (when the valve is closed) I want the pressure on the valve to...

Thanks everyone, I have considered the dead leg filled with a gas (air) but believe a pulsation dampener in which I could control the pressure inside the bladder or bellow would be best. This would allow me to vary the energy absorbed in the line and hopefully help produce the desired back...

Hello Everyone, I am looking for an small (a few cubic inches), adjustable pulsation dampener that that will operate at low pressures (1-30psi). Most dampeners that I have come across are quite large and are designed to be used in high pressure systems (1000psi and up). Please inform me if...

Hello, I am trying to devise a system in which I can cycle a small check valve using a water at a high frequency (20-50Hz). The problem is that I would like a closed system and be able to supply a back pressure to the closed valve up to 35 psi while allowing the fluid to circulate to the...

Hello, I am trying to devise a system in which I can cycle a small valve using a liquid (probably water) at a high frequency (20-50Hz). The problem is that I would like a closed system and be able to supply a back pressure to the closed valve up to 35 psi while allowing the fluid to circulate...
