Which consequence results when undersized bladder accumulators cause hydraulic spiking?

A)Valve seat high-frequency pressure oscillation
B)Reduced actuator thermal expansion coefficient
C)Increased fluid bulk instantaneous modulus
D)Decreased system steady-state settling accuracy

💡 Explanation

High-frequency hydraulic spiking induces valve instabilities due to fluid's rapid compression and release, where the improperly sized accumulator enables pressure intensification, via pressure amplification. This results in valve instability because the system poorly damps, rather than altered thermal expansion under typical, stable temperature behaviors.
