SVR Global is one of the leading needle valve manufacturer in Canada. They provide accurate flow control solutions to a wide range of industries. Needle valves are mainly used in applications where the flow rates require fine regulation. The specially designed needle valves enable the accurate or minute regulation of fluids and gasses and, hence, result in optimum performance within the critical system.

What is a Needle Valve?

A needle valve is a type of valve that enables precise regulation of fluid or gas flow. It consists of a slender, tapered needle-like plunger that fits into a matching seat. By turning the valve stem, the needle moves in or out of the seat, adjusting the flow passage. This makes needle valves ideal for applications requiring accurate flow control and tight shut-off.

Working:

The fundamental principle of the needle valve is that the stem is screwed in or out of the seat, thereby controlling the available flow area for fluid or gas. Since the valve is opened fully, the fluid flows quite freely and, as the needle is screwed down, this depletes the flow to give an exceptionally good degree of control. Its finely threaded stem and narrow needle provide for an exceptional degree of flow regulation-even to low-flow systems.
