Surge Protector / Buffer Between regulator and valves

Surge Protector / Buffer Between regulator and valves

Surge Protector / Buffer Between regulator and valves

(OP)
I'm trying to size a fluid buffer or surge protector for a small hard piped manifold which has a 1500psi output regulator and a number of small valves.

We've experienced (in the past) regulator jacking (rapid open/close cycle) when there isn't enough fluid capacitance in the circuit between the source (regulator) and the operator.

I could simply put in the largest bladder accumulator that would fit, but I'd like to be more discerning. Is there a rule of thumb or simple calculation to put me in the ballpark?

RE: Surge Protector / Buffer Between regulator and valves

I'd be inclined to try a spring loaded piston type accumulator, with a volume on the order of one or two valves' volume.  Or a very small bladder accumulator.

I don't know of any sizing rules.

So...no formal methods for sizing pulsation dampers?

RE: Surge Protector / Buffer Between regulator and valves

Didn't Peter's article have enough formulas for you?

If you want to do it the easy way check out Parker's online catalog.
