NEEDLE VALVE MANUFACTURERS IN INDIA

Speciality Valve is a top- rated Needle Valve Manufacturers in India that delivers high-precision needle valves to suit accurate regulation of flow for low-flow as well as high-pressure processes. Carefully designed to offer hassle-free performance, high efficiency, and durability, our needle valves are used across various industries.

Why Is It Needed?

Needle valves are required where highly precise control of flow is essential. They are used extensively in systems that involve gases or liquids where accurate flow adjustment and leak-proof shutoff are essential. Their fine-thread stem and tiny plunger make them ideal for sensitive control in process lines and instrumentation.

Major Components of Needle Valve:

1) Valve Body: Constructed from stainless steel, brass, or other non-abrasive materials
2) Stem/Spindle: Accurate motion and control
3) Needle/Plunger: Tapered tip controls flow through small orifice
4) Bonnet: Protects and guides the stem
5) Handle: Manual adjustment
6) Seat: Tight sealing when closed

Working Needle Valve:

The valve controls flow through a small orifice by actuating the needle-shaped plunger. Rotating the handle positions the plunger in the seat, gradually opening or closing the passage. Sensitive adjustment permits precise control of the flow.
