Replacement of Kidde Chemical Agent Cylinder Valve Assemblies
Please read the below information regarding the replacement of specific Kidde Chemical Agent Cylinder valves.
- Kidde fire protection has issued a safety bulletin requiring the hardware replacement of specific Kidde Chemical Agent cylinder-valve assemblies used in fire extinguishing systems for marine applications.
- The Affected cylinder valves are from NOVEC 1230 and HFC227 fire extinguishing systems.
- Kidde chemical agent cylinder has two-inch valve assembly which contains four retainer screws in its piston design. On the affected cylinders it is found that some valves with one or more of these retainer screws not tightened to the required torque specification and may have escaped production and inspection process before shipping.
- The loss of any of the screw from their set position will results into pressure equilibrium between cylinder and top chamber of the valve. In case of fire event when valve gets activated, the equilibrium causes the valve operation and prevents the agent from being discharge into affected space
- The affected products are with following valve markings and manufacture dates:
- 45-150000-001 2" Valve NOVEC - PI Mark- Jan 16, 2015 to December 31, 2016
- 90-150000-X0X 2" Valve HFC227 - PI Mark - Jan 16, 2015 to December 31, 2016
