Needle Valves

Product Description

Aneedle valveis a type of valve that allows for precise regulation of fluid flow in a pipeline.It consists of a slender, tapered needle-like plunger that fits into a matching seat, enabling fine control over the flow rate.

Construction and Operation:

The valve's key components include:

• Valve Body:The main housing that contains the internal components and flow passage.

• Bonnet:A removable cover providing access to the valve's internals for maintenance.

• Stem:A slender, tapered shaft that controls the position of the needle within the valve seat.

• Needle (Plunger):The tapered component that fits into the valve seat to regulate flow.

When the valve is closed, the needle is fully seated, blocking fluid flow.As the stem is turned and the needle retracts, a small opening allows fluid to pass.Further retraction increases the opening, permitting more flow.This design enables precise control over the flow rate, making needle valves ideal for applications requiring accurate adjustments.

Types of Needle Valves:

1. Straight Needle Valve:Features inlet and outlet ports aligned in a straight line, facilitating straightforward flow paths.

2. Angle Needle Valve:Has inlet and outlet ports oriented at a 90-degree angle, directing flow perpendicularly.

3. Multiport Needle Valve:Incorporates multiple ports for more complex flow control scenarios.
