Needle Valve
Middleeast valve is the well known for Needle valve suppliers in Sharjah. 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.
