Accelerator with Priming Restriction Accelerator with priming restriction
As part of the control trim, this venturi action accelerator speeds up the release of the main valve control chamber enabling faster full opening of the deluge valve. Water exits the accelerator faster than it can be supplied, through the restriction to the valve control chamber, accelerating the opening of the main valve.
