V-Notch Ball Valves: Precision Throttling and Shearing Power
A V-Notch Ball Valve features a ball with a "V" shaped cutout rather than a standard circular hole. This specific geometry allows the valve to act as a high-performance control valve. As the valve begins to open, the narrow part of the "V" exposes first, allowing for extremely fine flow increments that a standard ball valve cannot achieve.
How V-Notch Valves Perform
- Gradual Opening: Unlike standard valves that have a sudden "jump" in flow upon opening, the V-port allows for a smooth, linear increase in flow power.
- Shearing Action: The edge of the V-notch creates a "shearing" effect against the seal. This effectively cuts through fibers or solids in the media, preventing the valve from clogging or jamming.
- Superior Characteristics: The precision-contoured V-notch provides an Equal Percentage flow characteristic, which is the gold standard for process control.
Design Features of FlowBiz V-Notch Valves
- Robust Construction: Designed to withstand high-velocity fluids that would typically erode standard valves.
- Hard-Chrome Plating: The ball is machined to a super-smooth finish, hard-chrome plated, and polished. This reduces friction and drastically increases the service life of the seals.
- High Flow Capacity: Our design maintains a high Cv-to-body size ratio, providing high capacity and wide rangeability in a compact frame.
- Replaceable Seals: Features a replaceable ball seal and a backup ring, ensuring added rigidity and easy maintenance.
- Straight-Through Flow: The unobstructed flow path ensures minimal pressure drop when the valve is fully open.
