Durable, Economical & Easy to Install – Brass Needle Valves by Perfect Engineers
Perfect Engineers is one of India’s trusted manufacturers and exporters of brass needle valves, offering a wide range of high-performance, corrosion-resistant valves designed for low to medium-pressure fluid and gas applications.
Crafted from premium-grade brass and rigorously tested for leak-proof operation, our valves are ideal for water lines, air compressors, LPG systems, pneumatic applications, and low-viscosity fluids.
A brass needle valve is a manually operated valve used for fine regulation of flow. Made from a copper-zinc alloy, it combines moderate corrosion resistance with excellent machinability and affordability.
Ideal for air, water, inert gases, and fuel systems — NOT suitable for strong acids, chlorides, or ammonia.
