Needle Valves vs. Globe Valves: Precision at High Pressure
While both are linear motion valves, the needle valve is a specialized subset of the globe valve family. The primary difference lies in the design of the disk: the needle valve features a slender, tapered, needle-like plunger that fits perfectly into a matching seat.
Why Choose FlowBiz Needle Valves?
- Micrometer-Level Accuracy: The fine threading on the stem allows for very gradual movement of the needle, enabling operators to regulate flow with extreme precision.
- Extreme Pressure Rating: Specifically engineered for heavy-duty service up to 350 kg/cm², making them ideal for hydraulic systems and high-pressure gas sampling.
- Bubble-Tight Shut-off: Despite their small size, FlowBiz needle valves ensure zero-leakage isolation, protecting sensitive gauges and instruments downstream.
- Durability in Clean Media: Perfect for clean liquids and gases where contamination must be avoided and flow must be steady.
