Provides ultra-precise flow control with true linear flow characteristics across the full range of operation.
Unique dual-stem design with different thread pitch functions like a reduction gear for micro-movements of the needle.
Integrated needle and diaphragm in single PTFE component prevents media leaking into valve bonnet.
Small sealing cone around needle base ensures excellent seal while protecting needle from damage.
Parabolic design provides linear flow rate across full operational range for predictable performance.
Ultra-high purity, corrosion resistant PTFE and PFA wetted components for critical applications.
Both stems are threaded with different pitch that functions similar to a reduction gear. This unique actuation allows relatively large rotation of the handle to translate into micro movements of the needle, enabling very fine tuning of the flow rate.
The needle and diaphragm are integrated into a single PTFE component, eliminating potential leak paths and reducing particle generation. This novel design ensures maximum purity for critical applications.
The parabolic shape design provides true linear flow characteristics across the full range of operation, ensuring predictable and repeatable flow control for process consistency.
