Needle Valve

Needle Valve
Middleeast valve is the well known for Needle valve suppliers in Saudi Arabia. It is a type of flow control valve used to regulate the flow of fluids in a precise and fine-tuned manner. Its design features a slender, tapered needle-like stem that fits into a conical seat.

The primary function of a valve is to control the flow of fluid through a pipeline or system. It allows you to precisely adjust the flow rate by turning the threaded stem, which raises or lowers the needle-shaped plunger inside the valve.  It can also be used for isolation or shutoff purposes, although they are not typically used for full shut-off like ball valves or gate valves. They are better suited for throttling and fine-tuning flow.

Key components are:

Valve Body: The main body of the valve through which the fluid flows.
Needle-Shaped Plunger: The tapered, needle-like stem that fits into a small orifice within the valve body. As you turn the stem, it moves the plunger in or out of the orifice, regulating the flow.
Handle or Knob: The part of the valve that is rotated to control the flow. Turning the handle clockwise (closing) reduces the flow, while turning it counterclockwise (opening) increases the flow.
Inlet and Outlet Ports: These are the points where fluid enters and exits the valve.

Advantages:

The size of needle valves is smaller.
At low rates, the flow control is extremely accurate.
Accurate flow rate adjustments are possible.
They are capable of being throttled.
These valves are simple to shut off.
For the purpose of heating hot water, needle valves serve as bleed valves.
