What Is a Compression End Needle Valve?

There are many different types of valves you can use to promote fluid flow in your pipes. Are stainless steel compression needle valves the right type for you? A needle valve is a very precise type of valve with a thin, needle-shaped threaded plunger and a small port. The advantage of using a needle valve is that you can very precisely control the flow of fluid. However, due to the small opening, they are usually not appropriate for high-flow applications.

If precision is important to you and your application, though, there's no point in using anything other than Superlok stainless steel threaded needle valves from Mako Products. Quality and precision are our watchwords, and we work overtime to make sure each of our Superlok stainless steel needle valves meet very stringent quality and performance requirements.

If you're already using ss needle valves in your system and want to switch to superior Superlok needle valves, you won’t have any problem. Our ss needle valves are designed to be completely interchangeable with popular brands like DK-Lok, Swagelok and Parker.

Types of Superlok Needle Valves

Once you have determined whether or not your applications can use Superlok stainless steel needle valves, it's a matter of deciding which type of ss needle valves you require. There are a wide variety of sizes and features of ss needle valves, each appropriate for different types of uses in different industries.

Some of the variations in types of Superlok needle valves you will find include the following characteristics:

  • Tolerances up to 5,000 PSI or 6,000 PSI
  • Ability to withstand temperatures ranging from -65 degrees Fahrenheit to 600 degrees Fahrenheit or 1,200 degrees Fahrenheit
  • Made of 316 stainless steel and brass,
  • Forged or bar stock options

Why Choose Mako Products' Needle Valves?

Superlok needle valves have an airtight shut-off to stop leaks and provide a smooth regulation of liquids or gasses in instrumentation applications, ultimately increasing efficiency and lowering the cost by eliminating fluid waste. Superlok needle valves control the amount of flow with precision, while operating in the toughest conditions. Each needle valve is factory tested with pressurized nitrogen to 1000 PSI to ensure precision performance every time. Mako Products is the USA’s exclusive source for Superlok Needle Valves.

The proprietary i-Fitting red ring feature of our needle valves will be extremely valuable and cannot be overlooked. Never having to worry about leaks, bad connections or over-tightening can reduce your stress and save you a tremendous amount of time, not to mention money. Your workers can install our needle valves and know that once that red ring pops off, it is sealed, and they can move on to the next one — simplicity and safety you won’t get with other needle valves.
