Description
Technical Specifications
SPECS Small Flow Control Valves are compact and with high performance. They can be applied for the precise control of micro flow. For example, they are used by scientific research institutions for micro control of flow and pressure. The design pressure of valve body is up to 32Mpa, the minimum diameter of the plug can be 1mm and the minimum controllable Cv can be 0.001. This series are widely used for aerospace and hydrogen equipment.

Design Features
1. High pressure-resisting value, up to 32MPa
2. High precision control for small flow, minimum CV adjustment can be 0.001
3. Plug can be needle type or V type
4. Needle plug is with high sensitivity and easier to control
5. V type plug is strong, even in the case of a big pressure difference
Benefits
1. With long service life and high precision adjustment precision
2. Small plug is strong due to Special trim design
3. With special design to prevent blocking when controlling uncleaned medium in small gap.
4. Suitable for small flow control in medium of liquid, steam etc.
5. Valve body can be threaded connection
