Armstrong International K-2132 Main Diaphragm Kit

Armstrong GP-2000 Series Main Diaphragm Kit, part number K-2132, is a replacement kit for Armstrong GP-2000 pressure-reducing valves in the 1-1/4" and 1-1/2" line sizes. It is used to replace the main diaphragm assembly in GP-2000 valves to restore proper pressure control in steam and hot-water service. When installed as part of routine maintenance or diaphragm replacement, K-2132 helps the valve maintain its set pressure and stable operation, contributing to consistent system performance. The GP-2000 family covers diaphragm-based pressure regulation suitable for a range of industrial heating and process applications where reliable downstream pressure is essential. This K-2132 kit is designed specifically for GP-2000 units configured to the 1-1/4" and 1-1/2" sizes, making it appropriate for mid-range flow applications in commercial and industrial facilities. For technicians, confirm the valve size and model match K-2132 and follow standard Armstrong maintenance procedures during diaphragm replacement to ensure proper seating and seal function and minimize downtime.
