Precision Orifices
Precision orifices, also known as flow restrictors, regulate flow in pneumatic or fluid systems. These regulatory devices are available in many different sizes. The size of the orifice defines how quickly water or gas can pass through the system, and the resulting flow rate remains consistent with a high degree of accuracy. Airtrol Inc. supplies a full lineup of plastic precision orifices, molded with tight tolerances for maximal performance at low cost.
Airtrol molded restrictors feature accuracy comparable to jewel orifices at a fraction of the cost. Plain precision orifices have a straight connection for 1/16″ ID tubing. 17 color coded sizes ranging from 0.003″ to 0.040″ in diameter. Orifices with an integral filter and barbs for 1/16″ and 1/8″ ID tubing are available. The same 17 color codes are used and these barbed restrictors have the flow direction and orifice size marked on the body. In-line filters are also an option. These filters use the same sized bodies for 1/16″ and 1/8″ ID tubing.
Product Lineup
Precision Orifices
Precision molded orifices feature accuracy comparable to jewel orifices at a fraction of the cost. Color coded for easy identification.
Precision Orifices with Barbs
Feature integral filter to prevent clogging. Barbed connections allow higher working pressures. Color coded and clearly marked with size and flow directions. Barbs are for 1/16″ or 1/8″ ID tubing.
In-Line Filters
Disposable In-Line Filters have Type 304 stainless, Dutch weave screens. Clearly marked with size and flow direction arrow.
NV-30 Series Precision Needle Valve
The NV-30 series is a precision adjustable flow control used in pneumatic and fluidic systems. Nickel plated brass construction provides excellent corrosion resistance, and a clean and bright appearance. Flow control needle has 7 to 8 turns of precision adjustment, and maximum flow approximately equal to a 0.025″ orifice. Unique laminar flow design ensures sensitive, repeatable control. Perfect for use in application requiring precision gas metering, and circuit speed or sequencing control.
