Segment Ball Valve

The Fangwen segmented ball valve provides excellent modulating control with obstruction free design. The uni-body construction provides increased structural integrity and minimized leaks through body joints. The specially designed compound V opening provides precise equal percentage flow control with small incremental opening in the lower end of the valve rotation and high flow capacity in the upper end. The nearly wide open at full open, along with recessed bearings, virtually eliminates plugging/clogging of the valve.

O Port Ball Valve

An O port ball valve has either a 'o' shaped ball. This allows the orifice to be opened and closed in a more controlled manner with a closer to linear flow characteristic. When the valve is in the closed position and opening is commenced the small end of the 'o' is opened first allowing stable flow control during this stage. This type of design requires a generally more robust construction due to higher velocities of the fluids, which might damage a standard valve.

The Fangwen o-Port Ball Valves are quarter-turn control ball valves for accurate throttling control of fibrous suspension applications plus clean, dirty viscous, and corrosives liquids and gases. They are designed to meet the highest industry standards for dynamic performance. Flanged or flangeless designs meet ANSI or ISA face-to-face dimensions. o-Port Ball Valve design features include blow-out proof shaft protection, high flow capacity, splined ball-to-shaft connection for ease of maintenance and zero backlash. Seat options include flexible metal, rigid metal and PTFE seats.
