Overview
The Worcester 4444TSE ball valve is a three-piece design featuring carbon steel body construction, stainless steel trim, and TFE (Teflon) seats. Built to ASME B16.34 specifications, this 3/4 inch valve delivers reliable performance in industrial piping systems, hydraulics, pneumatics, and process applications requiring precise flow control and bubble-tight shutoff.
Key Features
- Three-piece slip-out body design allows quick access to seats and body seals for maintenance
- Bubble-tight shutoff with bi-directional flow capability for process flexibility
- Low operating torque enables use with compact actuators, reducing space and cost
- TFE seats and seals provide chemical resistance and extended service life
- Stainless steel ball and stem prevent corrosion in demanding environments
- Manual lever handle for easy manual operation
