Most Common Types of Sandblasting Media Valves

Abrasive types of media valves are actually used to adjust the flow of abrasive on a sandblasting machine. Same as with selecting the appropriate blast hose and blast nozzle, you want to ensure you select the correct type of media valve for the machine as well as the abrasive of your choice.

Sandblasting Colorado Springs

There are 2 types of metering valves: automatic and manual. Automatic valves have a mechanism or a system to shut down the flow of abrasive. These automatic valves are utilized on systems with Abrasive Cutoff Switches or Multi-operator pressure hold systems. ACS turn off media flow while allowing air to pass through. This is very useful for cleaning or blowing down the work surface. Manual valves, on the other hand, do not have to cut-off the flow of abrasive. Note that not every valve works with every abrasives or machines. In addition to that, not every valve works with the ACS or automatic cutoff switch.

Auto Quantum Valve

Auto Quantum Valve is commonly used for pressure-release systems as well as pressure-hold systems with abrasive cut-off. As a matter of fact, it is pneumatically-operated, easily-adjustable and maintains accurate settings from totally close to totally open. It can also be used with slag abrasives and expendable mineral. It needs 80 psi to totally open the plunger which may be used in all common abrasives such as metallic, slag or mineral. It comes standard on every sandblasting Colorado Springs contractor blast machine. It can also be used on traditional machines with automatic cut-off switches.

Sentinel Metering Valve with Automatic Cut-Off Switches

The sentinel metering valve is actually a pneumatically-operated abrasive valve with an ACS. This media valve is accessible with all usual blast media coarser. It can also be utilized on traditional blast machines 2 cubic feet and bigger equipment with a pressure-release controller (electric or pneumatic) and needs 50 to 70 psi to totally open its plunger.

Manual Quantum Valve

A manual quantum valve or the MQV is a manually-operated, and easily adjustable abrasive valve for use with every common abrasive such as metallic, slags and minerals. It is also designed for easy measuring and precise metering for both the classic blast machines and contractor 2 cubic feet and larger.

Sentinel Metering Valve Without Automatic Cut-Off Switches

The sentinel metering valve doesn’t have an ACS. It is perfectly suited for all common kinds of blast media coarser and is compatible on traditional blast machines 2 cubic feet and larger. Its valve needs 50 to 70 psi to totally open its plunger. Since the valve and metering actuation are different functions, the wear and tear of your metering assembly can be changed inexpensively and quickly in the industry.

Flat Sand Valve

It is basically a manually-operated abrasive valve which comes standard on traditional blast machines from 2 cubic feet to 20 cubic feet. Aside from that, it can be utilized with slag abrasives and expandable minerals. Note that the flat sand valve does not function well with metallic media mineral and slag abrasives.
