African Valve is the trusted Needle Valve Supplier in Chad. It is a type of flow control valve used to regulate the flow of a fluid through a system with very fine control and precision. It has a long, tapered point at the end of the valve stem, which is used to gradually open or close the valve seat. When the needle is fully seated, it forms a tight seal with the valve seat, preventing leakage. They are typically small and compact, which makes them suitable for applications where space is limited.

Working principle

It comprises of a small port and a threaded, needle-shaped plunger. When the valve is turned, the plunger moves either up or down. This movement allows the finest adjustments for the flow rate in the system. When the plunger moves down, it will block the orifice and reduce the fluid flow. Either way, when the plunger moves up, it opens the orifice and allows more fluid to pass through. Since the needle’s tapered end fits into the matching seat, it creates a tight seal and thus enables precise fluid control. When fully closed it creates a leakproof seal and prevents any fluid flow through it.

Components

• Body: this is the main structure that has all the internal components within it
• Bonnet: it helps to close the stem and other moving parts
• Stem: it is a slim rod with a pointed end that enables the regulation of the flow.
• Seat: it provides the seal around the needle for flow adjustments
• Handle: to helps to turn and adjust the needle to control the fluid flow.
