Spence E2-C2F9A1 Cast Iron Steam Control Valve

Spence E2-C2F9A1 Cast Iron Steam Control Valve is a 1-1/4 in NPT valve designed for low-pressure steam regulation. Based on Spence’s Type E2 main valve, it features a cast-iron body and a 1-1/4" NPT end connection suitable for standard piping. The valve is rated for up to 15 psig (1.03 bar) inlet pressure and temperatures up to 250°F (121°C), making it appropriate for HVAC steam circuits and light industrial process heating. The E2 main valve family provides compact, reliable throttling in steam lines, with the main valve material specified as cast iron for durability in hot, moist environments. This model is intended for use where precise flow control is needed at modest pressures, typically in applications such as regulating supply steam to coils, heat exchangers, or distribution manifolds in small to mid-size systems. The 1-1/4" NPT end connection and 15 psi rating are core specifications that define its compatibility with standard piping layouts and low-pressure steam service. The product name identifies the exact model: E2-C2F9A1, aligning with Spence’s E2 line of cast-iron steam control valves.
