Which risk significantly increases when a proportional control valve experiences high frequency dithering beyond its design limits?

💡 Explanation

When a proportional valve dithers at excessive frequency beyond its design, accelerated spool valve wear occurs because the rapid spool movements cause abrasive friction between the spool and valve body. Therefore valve wear results, rather than viscosity increase time reduction or pump efficiency decrease which involve distinct physical phenomena.
