Clemco Sentinel Metering Valve for fine grit media


The Sentinel Metering Valve is a pneumatically-operated valve without an Abrasive Cutoff Switch suitable for all common blast media NOT coarser than 50 mesh. The sentinel is compatible on classic blast machines 2 cuft and larger equipped with a pressure release remote (either pneumatic or electric). This valve requires 50-70 PSI to fully open the plunger. This manually-operated abrasive metering valve has a 1-1/2" NPT connection to the pot. 


  • Metering and valve actuation are separate functions so wear and tear of the metering assembly can be replaced quickly and inexpensively in the field.
  • The fail-to-safe design automatically stops the flow of media if either air or electric power is interrupted.
  • Can be configured for pressure-hold or pressure-release blast machines.
