FireLock Dry Accelerator, Series/Model: Series 746, Pressure Rating: 300 PSI, Material: 85-5-5-5 Bronze, 3-1/4 IN Width, 4.45 IN Height, Industry Standards: US/UL Listed, FM Approved

The Victaulic® series 746 dry accelerator is a pneumatically actuated valve that can be added to the Victaulic series 756 dry valves or the series 758 preaction valves in order to speed response time and/or accommodate larger systems. The series 746 dry accelerator is compatible with the Victaulic series 756 dry valves or the series 758 preaction valves that utilize a 753-A dry actuator, 776 low pressure actuator, or the 798 double pneumatic actuator. The dry accelerator attaches to the air supply's trim at the inlet of the dry actuator. The series 746 dry accelerator speeds the operation of the sprinkler's control valves by sensing the rapid decay of system pressure and exhausting air from the upper chamber of the actuating device.

• The series 746 features a unique, built-in check valve that allows rapid pressure equalization of the dry accelerator during system charging, and fast response to variations in system air pressure
• The series 746 dry accelerator is equipped with all required parts, and it is easily attached to the valve trim without additional modification
• The series 746 dry accelerator is rated to 300 PSI (2065 KPA) working pressure, and is tested and UL listed/FM approved for use with all sizes of Victaulic series 756 and series 758 fire safety valves
• The housings are durable, corrosion-resistant 85-5-5-5 bronze
• Internal components and fasteners are 360 brass and 300 series stainless steel
