Product Overview
The Manual 3-Piece Threaded Ball Valve is a highly reliable, hand-operated quarter-turn valve designed for easy thread-on installation in commercial and industrial pipelines. Equipped with an ergonomic manual handle, it allows for swift, absolute bubble-tight isolation.
The 3-piece structure is ideal for threaded lines: the female threaded end caps screw directly and tightly onto your pipeline. When maintenance is required, the body bolts can be easily unbolted, allowing the center segment to swing out for immediate cleaning or seal replacement without unscrewing the end connections from the pipe.
Key Mechanical Features
-
Lockable Handle Design: Fitted with a robust stainless steel lever handle and a heavy-duty vinyl sleeve. Includes an integrated safety locking latch to padlock the valve in a secure open or closed position (complies with industrial Lock-out/Tag-out safety standards).
-
High Flow Efficiency (Full Port): The full bore internal styling provides a smooth, unobstructed fluid pathway that matches the pipeline's exact inner diameter, maximizing $C_v$ ratings.
-
Inline Maintenance: Minimizes labor costs and operational downtime through its 3-piece bolt-together design.
