What Is a Brass Needle Valve

A brass needle valve is a type of valve with a small port and a threaded, needle-shaped plunger. The valve opening gradually becomes larger and can be adjusted continuously and finely from closed to open maximum. So it can accurately adjust the flow rate, Although it is only suitable for environments with a relatively small rate.

Structure of Brass Needle Valve

As we all know, both the brass needle valve and brass ball valve can control the flow rate. However, there is something different between them. In terms of structure, a needle valve has a tapered needle pressed against a seat. The ball valve has a ball that is connected to the inlet and has the same diameter bore.
