Printed in U.S.A. 12/21 P/N 9999970300 Bulletin 360 January 2021 Model FX Dry Pipe Valve 2â€ (50mm), 2-1/2â€ (65mm), 76mm, 3â€ (80mm), 4â€ (100mm), 6â€ (150mm), 165mm Features â€¢ Lightweight ductile iron body with compact trim â€¢ External reset reduces setup and commissioning time â€¢ Does not require priming water Product Description The Reliable Model FX Dry Pipe Valve is a differential-principle, externally resettable valve designed for use as a primary control valve in a dry pipe system. The valve clapper is held in the set position by pneumatic pressure acting on a larger surface area than that of the incoming water pressure. Release of pneumatic pressure from the system allows the dry pipe valve to open. The Model FX valve is available with grooved end, flanged end, or flange x grooved end connections (see Table A). When required, all sizes of the Model FX valve may be equipped with the Reliable Model B1 Accelerator (PN 650120001A; ordered separately). The accelerator is a normally closed valve that opens upon a predetermined rate of air or nitrogen pressure loss. When the accelerator opens, air or nitrogen pressure is directed to the intermediate chamber of the Model FX valve, hastening the valve trip time. Please refer to Reliable Technical Bulletin 323 for further Note: Pressure switches (low air and flow alarm) provided with information. fully assembled valves only. Order separately with loose and segmented trim.
