Product Overview
Needle valves are fully adjustable orifices designed to regulate flow with infinite adjustment capability from fully closed to maximum orifice diameter. These non-pressure compensated valves serve effectively as flow controls or shutoff valves.
Key Features
- Balanced adjustment mechanism enables easy operation even under high pressures
- Sharp-edged orifice design minimizes flow variations caused by viscosity changes
- Bi-directional flow path (preferred direction: port 1 to 2 for compatibility)
- Zero leakage when in shut-off position
- All 2-port flow control cartridges are physically and functionally interchangeable within the same frame size
