The Bedford 20-3031 is a direct-fit replacement for the piston valve and nut kit designed for Graco 190ES airless spray equipment, serving as a core rebuild component for pump service operations and field repairs.

Pump rebuild specialists and spray equipment technicians rely on this kit to restore proper piston function and valve sealing in 190ES pumps that have experienced performance degradation or fluid bypass issues. Professional painting contractors also stock this kit to minimize downtime when valve wear develops during high-volume spraying applications.

Common reasons for replacement:

  • Piston valve scoring or wear causing loss of pressure holding capability and fluid leakage past the valve seat
  • Nut corrosion or thread damage preventing secure reassembly of the valve cavity
  • Fluid bypass or inconsistent spray pattern resulting from worn piston-to-bore tolerances
  • Seal failure in the valve assembly leading to fluid seepage during idle periods or reduced pump efficiency

Manufactured to OEM-equivalent dimensions for proper fit and performance. Compatible Graco equipment models are listed in the Compatible Equipment section below, where available.
