Engineered for precision flow control, our needle valves are designed to deliver accuracy, durability and long-term reliability. With their fine-threaded stems and narrow seats, needle valves provide gradual, leak-tight shutoff and precise regulation of flow in demanding systems.
Our collection includes Carbon Steel, Stainless Steel, Brass, and High-Pressure Needle Valves, built for industrial performance and available across the U.S. From process lines and instrumentation systems to high-pressure operations, these valves are dependable solutions designed to meet industrial requirements.
Needle valves are essential in industrial systems where precise flow regulation is critical. Their construction offers several advantages:
Accurate flow control for gases, liquids and steam.
Leak-tight sealing even at high pressures.
Compact design suitable for instrumentation and sampling lines.
Compatibility with a wide range of materials and system requirements.
Easy operation with fine-thread stem for smooth adjustments.
Designed with a fine-thread stem and tapered seat for accurate flow regulation.
Provide leak-tight shutoff in low- to medium-pressure systems.
Common in general instrumentation, chemical plants and laboratory setups.
Engineered for systems needing multiple outlet connections from one valve body.
Simplify piping layouts while maintaining precise flow control.
Used in industrial instrumentation panels and high-pressure test systems.
Built with a 90-degree outlet for compact installations and efficient piping layouts.
Reduce the need for additional fittings, lowering pressure loss and space requirements.
Ideal for chemical plants, power stations and instrumentation panels.
Lightweight, corrosion-resistant and easy to install.
Offer cost-effective flow control for HVAC, plumbing and light industrial systems.
Widely used in air, water and low-pressure gas applications.
Deliver excellent corrosion resistance and temperature tolerance.
Suitable for chemical, marine and food-grade processing systems.
Provide clean, reliable performance in harsh environments.
Strong and durable, made for heavy-duty applications.
Ideal for oil & gas, refineries and high-temperature services.
Dependable option when strength and toughness are required.
Oil & Gas Pipelines: Needle valves control pressure, sampling and instrumentation flow lines in upstream, midstream and downstream operations. Their accuracy ensures safe and efficient energy operations.
Chemical Processing: Corrosion-resistant stainless steel and alloy needle valves regulate aggressive chemicals, solvents and process fluids, maintaining safety and purity in demanding plant environments.
Power Generation: Needle valves handle steam, water and auxiliary lines in power plants. Their precise regulation supports efficiency and safety in thermal and nuclear systems.
Water Treatment Systems: Used for dosing chemicals and controlling sampling lines, needle valves provide accurate regulation with minimal leakage, essential in treatment facilities.
HVAC and Industrial Systems: Brass needle valves regulate air, water and refrigerants in HVAC and light industrial systems. Their compact design fits easily into tight system layouts.
Instrumentation and Testing: Multi-port and high-pressure needle valves are critical in instrumentation panels, hydraulic test benches and laboratory setups requiring reliable accuracy.
When selecting a needle valve, consider the following factors:
Material: Brass for light-duty, stainless steel for corrosion resistance, carbon steel for strength, high-alloy for aggressive media.
Pressure Rating: Standard for low/medium pressure, forged steel for high-pressure service.
Size & Connection: Threaded, compression or NPT ends based on system design.
Temperature Range: Match seat and body material to process temperature.
Operation Needs: Standard handwheel for manual adjustment or panel-mount options for instrumentation use.

What is a needle valve used for?
Needle valves are used to precisely regulate flow in pipelines, instrumentation systems and sampling lines where accurate control is required.
Can needle valves handle high pressure?
Yes, high-pressure needle valves are designed with robust materials and construction to handle pressures up to 10,000 PSI or more.
Are brass needle valves suitable for industrial use?
Yes, brass needle valves are reliable for HVAC, plumbing and light-duty industrial systems, though stainless steel or carbon steel is recommended for harsher environments.
How do I choose the right needle valve?
Selection depends on material compatibility, pressure rating, connection type and the required level of flow control precision. Consulting a trusted supplier simplifies the process.

Excellent product and service thanks
I paid for this thing 2 weeks ago. It never shipped. Was told UPS was at fault, then they stopped replying to my emails.
Perfecting crafted!
Teflon stud/nuts delivered in 4 business days. I held back 1-star because pricing increased 40% in 30-days. I’m guessing because they needed to outsource these. ( Shipped by third party). Although, the speed of order fulfillment was excellent!
Parts were as advertised and worked just as I needed.
