HPAD ROOF ISOLATION VALVES AEV C-BALL

The National Research Council Canada, through the Propulsion and Power Laboratory, has issued an Advance Contract Award Notice (solicitation 26-58150) for the engineering, design, supply, and commissioning of two Class 900, 10-inch full-bore ball valves. These valves are intended for High-Pressure Air Distribution isolation and must be capable of operating in severe-service environments with temperatures reaching 1500°F. The scope of work includes the delivery of two complete valve assemblies equipped with pneumatic actuators, engineering design documentation, a commissioning spare parts package, and warranty support. All equipment must be delivered by March 31, 2027. Technical specifications require the valves to feature Raised Face double-flanged end connections, ASTM A351 Grade CF8C body and bonnet materials, and Alloy 718 stems. Additional requirements include AISI 321 stainless steel seats with Stellite hard-facing, an extended bolted bonnet with cooling fins, and live-loaded graphite packing, with seat leakage performance adhering to API 598. While Laurentide Controls has been pre-identified as the intended supplier due to these unique technical requirements, the government will consider statements of capabilities from other qualified suppliers submitted by September 25, 2026.
