Amerex Valve Stem Assembly KP 13600 - OEM

The Amerex 13600 is the OEM stainless steel valve stem assembly for Amerex KP commercial kitchen fire suppression cylinders. Like the plated version (15063-P001), the valve stem is the central component of the KP cylinder's discharge valve it opens when the system activates to release wet chemical agent toward the suppression nozzles. The stainless steel construction of the 13600 provides superior corrosion resistance compared to the plated version, making it the preferred choice for KP systems installed in coastal restaurants, seafood processing kitchens, high-humidity environments, or anywhere the wet chemical agent environment combined with ambient conditions creates accelerated corrosion risk.

Stainless steel valve stems maintain their dimensional precision and seating surface quality over multiple service cycles better than plated alternatives in highly corrosive environments. A corroded or pitted valve stem seating surface can cause the discharge valve to seal improperly after post-discharge service, either leaking agent slowly between service intervals or failing to open fully when the system fires. The 13600's stainless construction minimizes these risks in demanding environments.

The 13600 is an OEM Amerex part that maintains the KP system's UL 300 listing. It is replaced as part of the 6-year internal examination procedure using the KP valve rebuild kit (20659), and inspected after any discharge event. Available through authorized Amerex distributors. Verify this is the correct valve stem for your specific KP cylinder model using the Amerex KP system parts documentation before ordering. The plated (15063-P001) and stainless steel (13600) versions are designed for different configurations.

Inspect the 13600 stainless steel valve stem during the 6-year internal examination of the KP cylinder per NFPA 17A. Even stainless steel can show wear or pitting on the seating surfaces after multiple service cycles. Check carefully for any surface damage that could prevent a complete seal. Replace with a new 13600 if any defect is found. In standard commercial kitchen environments without elevated corrosion risk, inspect at the same intervals as the plated version; in high-salinity or high-humidity environments, inspect more frequently and consider proactive replacement at each 6-year interval regardless of apparent condition. Document in the fire suppression system inspection record.

Can I upgrade from the plated (15063-P001) to the stainless steel (13600) when replacing?

Only if the Amerex KP system parts documentation for your specific cylinder model lists both versions as compatible. Do not substitute the stainless steel version for the plated version without verifying compatibility. The two are designed for different KP configurations and may not be interchangeable in all applications. Your authorized Amerex distributor can confirm whether the 13600 is an approved replacement for your specific KP cylinder model.
