(OP)
Hi
Please could someone clarify something.
To maintain an upstream pressure within a hydraulic system in which the change in viscosity has to be compensated for am I correct in this understanding that the upstream pressure will be maintain as the pressures across the ball will adjust to the change in viscosity. IE, the higher the viscosity the lower the internal pressure of the liquid and the lower the viscosity the higher the internal pressure the spring on the down stream side martini the same pressure of the fluid flowing between the contact edge and of the ball and therefore the spring on the down stream will adjust to the change in viscosity thereby maintaining the same upstream pressure?
Is that correct?

RE: Hi Please could someone clarify s

i'm having a little difficulty understanding the question; the martini is throwing me off. are you asking if the spring constant changes as viscosity of the fluid changes? is the sketch of a pressure relief valve?

RE: Hi Please could someone clarify s

Wrong forum. Try Fluid Power Engineering.
