Xylem 402409 Series 2100 Pressure Reducing Main Valve 1-1/4" NPT Full Port

The Xylem 402409 is a Hoffman Specialty Series 2100 pilot-operated pressure reducing main valve designed for steam service applications. This 1-1/4" NPT full port valve features cast iron construction and is designed to work with pilot control valves to maintain accurate and stable pressure control in steam systems.

Key Features:

• 1-1/4" NPT threaded connections with full port design for maximum flow capacity
• 2-ply stainless steel diaphragm provides greater accuracy of control over entire capacity range and extended service life
• Packless construction eliminates many common service problems and maintenance requirements
• Positive travel stop and diaphragm backup prevents over-pressurizing from the downstream side
• Normally-closed, single-seated design for reliable operation
• Cast iron body with 30,000 psi tensile strength
• Designed for continuous or dead-end service within 0.01% leakage of rated capacity

Part of the Hoffman Specialty Series 2000 pilot-operated regulator system, this main valve is held closed by internal spring pressure and controlled by pilot valves that regulate steam flow to the diaphragm. The Series 2000 line offers over 55 main valves with 24 pilots for hundreds of possible combinations to meet various temperature, pressure, and capacity requirements in commercial and industrial steam applications.
