Valves Only is one of the best manufacturers of needle valve in the USA. Meeting the needs of industries is our mission. Valves play a key role in controlling the flow of liquids and gases in different industries to achieve efficacy and safety.

Among the different types of valves, needle valves find great value for their accuracy in controlling flow. These valves are mostly used in the fields of oil and gas, chemical processing, and power generation.

How Do Needle Valves Work?

The needle valve is invented for precise control over fluid flow. As the handle is turned, the needle moves in or out to adjust the size of the passageway fluid would flow through.

The mechanism of operation allows flow rates to be controlled, and therefore a needle valve is considered the best for applications requiring exact flow rate adjustments. Its design renders a needle valve exempt from sporadic pressure surging and a steady and uniform flow regulation which makes it apt for sensitive instruments and high-pressure working environments.

Benefits Of Needle Valves

· Durability: Needle valves are made from high-quality materials like stainless steel and duplex alloy, giving them great resistance to corrosion and wear, along with extreme temperatures. Sturdily built, needle valves yield longer lives and less maintenance needs even in grueling operating conditions.

· Versatility: Needle valves are extremely versatile in nature. They find wide applications in chemical processing, petroleum refining, power generation, and gas distribution. The ability to precisely control flow rates makes them a vital component of laboratory equipment, hydraulic systems, and instrumentation processes.

· Prevention Of Pressure Surges: Needle valves are unique in that they can withstand high-pressure conditions without any negative effects on performance. In other words, the seal is more rigid and leak-proof and offers more resistance to pressure variation. This means they work very well in demanding applications, such as oil and gas pipelines, steam control, and high-pressure testing systems.

Essential Parts of a Needle Valve

Body: The main structure that holds

The needle or stem: It moves up and down to control the discharge of flow.

The seat: forms a tight closing and sealing when the valve is commanded to close.

Handle or Hand Wheel: For manual use of the valve.

Bonnet: Covers and protects internal components.

Packing: Prevent leakage around the stem.

Types of Needle Valves

¨ Straight needle valves: It is designed for straight-line flow applications.

¨ Angle Needle Valves: It is used for 90-degree directional flow changes.

¨ Multi-Turn Needle Valves: It provides gradual flow control with multiple turns.

¨ High-Pressure Needle Valves: Built to withstand extreme pressure conditions.
