350 PSI Female / Male NPT Brass Propane Needle Valve Manufacturer, Supplier, Exporter in India

Mcneil Instruments specializes in Brass Needle Valves, featuring a compact port and a threaded plunger resembling a needle for precise flow control. The 1/2 Npt Brass Needle Valve offered by Mcneil Instruments enables accurate regulation of flow, while the 3/8 Npt Brass Needle Valve, typical for the brand, is suitable for lower pressure flow rates.

Mcneil Instruments offers a range of high-quality High Pressure Instrumentation Female Brass Needle Valves, including the 1/4″ Brass Mini Needle Valve – 1500 PSI Female to Female. These valves are suitable for various applications, including vacuum systems, where precise control of gas or fluid flow is essential.

The 1/4 Inch Brass Needle Valve is particularly useful in low-pressure tasks such as filling gas-filled vacuum tubes or gas lasers. Brass, known for its excellent corrosion resistance properties, is the primary material used in these valves. Additionally, the inclusion of aluminum in the Brass Needle Valve enhances its corrosion resistance, forming a protective aluminum oxide layer on the valve’s surface. This layer acts as a self-repairing barrier against corrosion. Furthermore, the addition of manganese and iron, along with aluminum, improves the wear and tear resistance of the Brass Gas Needle Valve. Trust Mcneil Instruments for reliable and durable instrumentation solutions for your industrial needs.
