Valve, abr mtrg, Sntl, fine mesh

The Sentinel accurately meters all common blast media from coarse steel grit to Green Diamond to Black Beauty to fine Glass Bead. Just empty the blast machine, pour in the new media, and start blasting.

For blast contractors, the Sentinel's flexibility reduces downtime between jobs that require different blast media.

For rental outlets, installing Sentinel valves makes every blast machine ready to roll out the door regardless of the application. Any common blasting media the customer chooses will be compatible.

Engineered For Lasting Economy

Metering and valve actuation are separate functions in the Sentinel, so the wear items in the metering assembly can be quickly replaced in the field.

When the valve is open, the plunger is completely withdrawn from the media flow. When the remote control handle is released, the spring actuated Sentinel instantly stops the flow of media. 

The Sentinel's fail-safe design stops the flow of media if air or electric power to the remote controls is interrupted for any reason.

The metering section of the Sentinel incorporates a stainless steel metering plate for long life. This metering plate aIlows fine adjustment no matter what media is used.

An optional inspection plate lets the operator check for foreign objects and media blockages without disassembling the valve. 

Versatile

The Sentinel can be configured for pressure-hold or pressure-releas blast machines, with or without remote media shutoff. It works with pneumatic or electric remote controls.

The Sentinel instaIls in minutes on any Clemco single or multiple-outlet blast machine.  It can be adapted to machines from most other manufacturers as well. 

Abrasive Cutoff Switch (ACS) 

The electric or pneumatic Abrasive Cutoff Switch, a standard feature of all Sentinel Remote Control Systems, allows use of compressed air from the blast nozzle for dust blow down. A switch at the nozzle opens and closes the media valve without actuating the air valve. When blasting is completed, the operator simply flips the ACS switch to off, which closes the Sentinel Media Valve completely. The air valve remains open so that only high velocity air flows from the nozzle. Releasing the RLX Remote Control Handle shuts off the entire unit.

The ACS can be easily added to most remote control systems which incorporate a pneumatically operated metering valve.  ACS must not be used to blow lead-contaminated dust or other hazardous materials.
