Why Choose LowFlow?
LowFlow valves are engineered for applications where accuracy at very low flow rates is critical, something conventional control valves struggle to achieve. Key benefits include:
- Exceptional low flow accuracy: Precise fluid control down to extremely low Cv values.
- Wide range of flow characteristics: Multiple Cv options available within each individual valve size.
- Flexible trim configurations: Easily adapted to changing process requirements.
- Quick-change trim design: Fast inline maintenance with no specialised tools required.
- High repeatability and stability: Ideal for precision research, sampling, and dosing applications.
- Compact design: Perfectly suited to space-constrained laboratory layouts and skid systems.
LowFlow valves are designed to be easily configurable with interchangeable trims and flow characteristics, allowing users to fine-tune performance without removing the valve body from the pipeline loop.
Technical Guidance: When to Specify LowFlow vs Standard Control Valves
Standard industrial control valves are typically designed for macro-flow management. When forced into fractional fluid loops, standard valves face severe performance degradation. Choosing a dedicated LowFlow valve solves several distinct operational issues:
- Eliminate Valve Hunting: Conventional valve trims struggle near their seat limit at micro-flows, causing the system to continuously overshoot and hunt. LowFlow fractional designs offer tight, stable control profiles down to fractional Cv targets.
- Avoid Cavitation & Rapid Trim Wear: Oversized standard valves crack open only slightly to meet low flow demands, creating high-velocity gaps that destroy plugs and seats. LowFlow configurations spread the pressure drop across custom-tuned trim shapes.
- Rapid Inline Reconfigurability: Research parameters and pilot lines change frequently. Standard valves require full replacement or workshop machining to modify flow coefficients; LowFlow trims can be completely swapped inline in minutes.
