An essential part of an automatic blast vessel, the abrasive charge valve allows the upper chamber to fill while the lower chamber remains pressurized.  When the grit supply in the lower chamber needs to be replenished, the internal charge valve opens, allowing the abrasive to fall into the lower chamber from the upper chamber.  Because the operators can continue working during this process, efficiency and production is greatly increased.

We recommend that our customers keep a spare charge valve on hand to reduce downtime.  When the charge valve needs to be repaired (typically a new cylinder, diaphragm repair kit or rubber ring), we suggest they remove the entire unit from the vessel and replace with the on-hand spare.  Then, any necessary repairs can be done on the bench using less time and with better working conditions.  Repair the charge valve and put it back on the shelf for next time it is required.
