Needle Valve Manufacturer in India

Speciality Valve is the best Needle Valve Manufacturer in India. We supply to Gujarat, Kerala and Punjab. A needle valve is a specialized type of valve employed to regulate the flow of liquids or gases within a system. Its name is derived from the thin, pointed, and curved stem, often referred to as the "needle," which resembles an actual needle. This needle is housed within a threaded opening or seat. These valves are recognized for their exceptional control capabilities, making them well-suited for applications demanding precise and accurate flow control. A needle valve operates by using a long, tapered needle-shaped plunger, which fits into a matching seat. As the valve stem is turned, the needle is either withdrawn from or pushed into the seat, altering the opening for flow. This precise adjustment allows for fine control of flow rates, making needle valves ideal for applications requiring precise regulation, such as in instrumentation and flow metering systems.

Needle valves find widespread use in industries such as oil and gas, chemical processing, and industrial equipment, particularly in situations where even minor adjustments in flow rate or pressure can significantly influence the operation. We manufacture Needle Valve in different materials and sizes.

Parts:

1. Body of the Valve: The body is the main housing of the needle valve, typically made of metal or other durable materials. It provides the structure and housing for the other components of the valve.
2. Bonnet: The bonnet is a removable cover or cap that is connected to the body of the valve. It provides access to the internal components of the valve, such as the stem and packing gland, for maintenance or repair.
3. Stem: The stem is a cylindrical rod that extends from the bonnet down through the body of the valve. It connects to the needle and allows for the control of the needle's position within the valve.
4. Needle: The needle is a long, tapered plunger that fits into a matching seat within the valve body. It is attached to the stem and is responsible for controlling the flow of fluid through the valve by adjusting its position within the seat.
5. Seat: The seat is a machined surface within the valve body where the needle makes contact to control the flow of fluid. It provides a tight seal when the needle is fully seated, preventing leakage.
6. Handle: The handle is an external component attached to the stem or bonnet, which allows for manual operation of the valve. By turning the handle, the stem and needle can be rotated to adjust the flow of fluid through the valve.
7. Packing or Packing Gland: The packing, also known as the packing gland, is a seal located around the stem where it passes through the bonnet. It prevents leakage of fluid from the valve along the stem. The packing gland can be tightened or adjusted to maintain the integrity of the seal.
