LowFlow Valve is a specialist manufacturer of precision control valves and pressure regulators engineered specifically for very low flow applications. As part of Richards Industrials, LowFlow products are designed to deliver highly accurate and repeatable control in demanding environments such as laboratories, pilot plants, OEM systems, and research facilities. At Premier Control Technologies, we supply the full LowFlow range, supporting UK and Ireland customers with expert sizing, specification, and application advice for critical low-flow processes.
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.
