A 3 Piece Handle Ball Valve Screwed End is a three-part body ball valve operated by a lever handle, designed to serve just about every conceivable flow control application. Made from bar stock, sand casting, or investment casting in materials like SS 304, SS 316, SS 316L, IC CF8, and IC CF8M, built for durability and ease of maintenance. Available in sizes 15mm to 300mm. Explore our Ball Valve range or compare with our 3 Piece Ball Valve Flanged End .
Suited for general industrial flow control, process piping, and plumbing applications requiring manual, handle-operated on-off isolation with easy maintenance access via the three-piece body.
The ball, housed in the center body section, rotates 90 degrees on the stem when the handle is turned. In the open position, the ball’s bore aligns with the pipe, allowing unrestricted flow. Turning the handle a quarter-turn rotates the ball so its solid surface blocks the flow path completely. The three-piece body allows the center section to be unbolted for maintenance, giving access to the ball, seats, and seals without disturbing pipeline connections.
Allied Engineering manufactures 3 Piece Handle Ball Valves with a wide choice of materials and manufacturing methods, ensuring durability across industrial applications. With BS 5351 compliance, multiple end connection options, and years of industry experience, we deliver valves built for dependable, long-term performance.
