Instrumentation Valve

Best Needle Valve Manufacturers in India


Mcneil Instruments specializes in manufacturer, supplier, and exporter of Needle Valves that cater to a diverse range of industries. These products serve to regulate the flow of gases and liquids with precision, allowing for controlled resistance to flow and safeguarding delicate gauges against sudden surges of pressurized substances such as water, oil, or gases. Ideal for scenarios requiring a gentle reduction in flow or where minimal flow rates are necessary, as a leading Needle Valve Manufacturers, Mcneil Instruments’ Needle Valves are in high demand. They offer versatility, functioning effectively under throttling, fully open, or fully closed conditions. Similar to globe valves in function, these valves stand out for their ability to provide secure, leak-free connections, making them the preferred choice for applications demanding precise flow control.

An instrument Needle valve uses a tapered pin to gradually open a space for fine control of flow. The flow can be controlled and regulated with the use of a spindle. A Needle valve has a relatively small orifice with a long, tapered seat, and a needle-shaped plunger on the end of a screw, which exactly fits the seat. These Needle valves are an ideal option for isolating or throttling applications. The self centering, non rotating stem ensures perfect seating. The rigid design gives repetitive bubble tight shut off, easy.

Mcneil Instruments’ Needle Valve operates on the same principle as screwed stem globe valves. The distinction lies in its design: instead of a plug point, Mcneil Instruments’ needle valve features a needle point. Activation is achieved by a t-bar, rotated to drive the needle into the seat. The sealing interface occurs as the needle passes through and seals on a conical area machined inside the body. With a maximum working pressure of 10,000psi and a maximum working temperature of up to 230°C or 427°C with the GP option, Mcneil Instruments ensures reliable performance even under demanding conditions.
