Needle valves | Choosing the right valve
Needle valves are used in particular for the regulation of low-flow liquids or gases. These are small diameter valves designed for low pressure applications. They are generally manually operated. They are very often found in domestic applications and fluid sampling operations. They are inexpensive which explains why they are so popular.

How to choose this product
needle-valve

Needle valves are linear devices. The movement of the closure element is perpendicular to the fluid flow.

Applications

These valves are used for precise flow regulation, especially when a low, constant flow is required.

Technologies

Such valves have a small orifice with a long, conical seat. The needle-shaped closure element, or plunger fits the seat contours perfectly. Single acting models allow flow control in one direction and free flow in the opposite direction. Double acting valves control flow in both directions.

Advantages

- Precision
- All-metal construction
- Simplicity
- Stability

Disadvantages

- Low flow rate only
