Flowserve-Worcester Valve 4446PMSW.100 Ball Valve
The Flowserve-Worcester 4446PMSW.100 is an industrial-spec 1-inch manual ball valve from the legendary Series 44, designed for critical high-pressure fluid control. This three-piece carbon steel ball valve features a robust body rated for 1480 PSI (ANSI Class 600), making it a standard choice for steam, chemical processing, and hydraulic systems where reliability is non-negotiable. The socket weld (SW) ends ensure a permanent, leak-proof connection in high-stress piping environments, while the swing-out center section allows for easy seat and seal maintenance without fully removing the valve from the line.
Integrated with high-performance Polyfill (P) seats and Multifill (M) seals, this valve maintains bubble-tight shutoff across a wide temperature range, typically from -50°F up to 600°F depending on active line pressure. The 316 stainless steel ball and blowout-proof stem provide superior corrosion resistance and operator safety. For technicians looking to automate, the 4446PMSW.100 utilizes a standardized mounting pattern compatible with Worcester pneumatic or electric actuators. Whether you are handling saturated steam or abrasive process media, this Flowserve industrial valve delivers the mechanical integrity required by modern HVACR and industrial contractors.
Key Benefits for Contractors:
- 1480 PSI Pressure Rating: High-tensile carbon steel construction meets ANSI Class 600 standards for demanding industrial applications.
- Serviceable 3-Piece Design: Simplifies maintenance by allowing the center section to swing out, reducing downtime during seal replacements.
- Leak-Proof Socket Weld Ends: Designed for permanent installations where vibration or thermal cycling could compromise threaded connections.
- Polyfill Seat Technology: Provides excellent wear resistance and thermal stability for high-cycle industrial environments.
- Stainless Steel Trim: Standard 316SS ball and stem enhance durability and prevent seizing in harsh service conditions.
Common Questions:
What is the difference between socket weld and threaded connections for this valve?
The socket weld ends on the 4446PMSW.100 are intended for welded piping systems to eliminate potential leak paths found in NPT threads, especially in high-vibration HVACR or process steam applications.
Can this valve be used for steam service?
Yes, when equipped with Polyfill seats, the Worcester Series 44 is highly effective for saturated steam applications up to 250 PSI and thermal fluids at higher pressures.
Is this valve compatible with pneumatic actuators?
Absolutely. The center section is designed to accept standard Worcester mounting kits, allowing for easy field conversion from manual to automated operation.
