Blast-One Weekly Tips
Tip #96
What is the number of turns required for optimum efficiency on a Thompson valve?

Have you ever wondered about EXACTLY how much abrasive is being pushed out of the blast machine?

It’s an interesting fact – and without measuring the supply of the abrasive you WILL be losing money – and possibly losing your PROFITS.

Well, there is good news – we can ensure your productivity, grain for grain, the consumption and efficiency of your blast system.

The answer is the Thompson Valve – it’s not new, and those who fit these metering valves to their blast system fully understand the benefits!

Here’s how it works

4 turns open means 100% abrasive economy (*using Australian GMA superior quality abrasive).

Fast start/stop for spot blasting

For those projects where you must only blast small areas or rust spots, you’ll appreciate the very fast on/off control the Thompson II Valve™ allows. Blast a spot there and another over here without ‘dragging’ the blast and damaging the coating in between. The Thompson II Valve™ gives almost instantaneous starting and stopping control.

Abrasive cut off and blowdown option

A remote abrasive cut-off is available for Thompson Valve™ systems, allowing you to stop the flow of abrasive, while continuing to blow air only. This provides a quick and easy way to clear the blast hose and to blow the blasting area clean of abrasive. Just flick the optional switch at the Deadman handle.

Also – if you’re focused upon results – the Blast-One Media Flow Detector is an ideal fitting to your blast system:

Features
  • For all types of media
  • Requires little maintenance due to no moving parts
  • Operates from 24 Vdc
  • Relay contact output
  • Push-button setup
  • LED indicators
Abrasive Consumption Monitor

The Blast-One Media Flow Detector is a media flow detector for pressure-type abrasive blasting machines. The sensor uses a charge-coupled amplifier that is connected to a sensing ring placed in the flow path of the abrasive blasting media. Each particle passing the ring shares a minute charge with the ring, converting it to a voltage used to activate the output relay contact.
