Overview
The Flowserve 1 4446RTSE R2 ball valve is part of the Worcester Controls Series 44 standard ball valve line, manufactured by Flowserve Corporation. This 1-inch threaded valve combines an A105 carbon steel body with 316 stainless steel ball and stem, delivering robust performance in industrial piping and fluid power systems. The RTFE (TFE) seat and seal material provide chemical resistance and reliable shutoff across a wide range of industrial media.
Key Features
- 1-inch NPT threaded connection — Direct screw-in installation with standard pipe threads
- A105 carbon steel body — Durable, economical casting for general-purpose applications
- 316 stainless steel ball and stem — Superior corrosion resistance and smooth operation
- TFE (RTFE) seats and seals — Chemical-resistant, reliable shutoff with minimal maintenance
- 1440 PSI CWP rating — Safe working pressure suitable for mid-range industrial systems
- 500°F maximum temperature — Handles elevated-temperature fluids without seal degradation
