Viking™ Replacement Clapper Assembly for F1 & F2 Dry Valves
This Viking™ Clapper Assembly serves as a replacement clapper for 3 in. & 4 in. Model F1 & F2 Dry Valves. It features a spring-loaded assembly designed to provide a positive mechanical seal, filling a dry pipe fire sprinkler system with water when air pressure drops. Constructed of Ductile Iron, this replacement clapper features 2 x PTFE Coated Steel Bushings, a Stainless 3/8 in.-16 x 3/4 in. Cap Screw, a Stainless Rubber Retainer and a Ethylene Propylene Rubber Ring.
To replace the existing clapper assembly in Model F1 & Model F2 Dry Valves, first ensure that the existing assembly is latched in the open position. Never reach into a dry pipe valve when the clapper is closed.
Hold the spring-loaded clapper arm assembly down and remove a retaining ring from one end of the clapper rod. Release the spring-loaded clapper arm assembly, allowing it to lock in the open position. Slide the rod out of the clapper arm assembly. Then, remove the existing clapper assembly and install this Viking™ Clapper Assembly for 3 in. & 4 in. Model F1 & F2 Dry Valves by following these steps in reverse order.
Refer to manufacturer data sheet for specific installation instructions.
