Customer Reviews
Mike Anderson “I recently integrated the Numatics 3FC2 Inline Flow Controls into our production line after a series of failures with a competitor’s fittings. The 360-degree swivel body was a game-changer for our compact manifold setup, as it completely eliminated the need for extra elbow fittings. We’ve been back in business for three months now without a single leak or pressure drop, and the screw adjustment remains incredibly precise even under high-vibration conditions.”
Victoria Yarborough “Our facility switched to ASCO Numatics for our primary solenoid valve needs, specifically the Series 256, and the quality construction is undeniable. We use them for fluid control in our food processing plant, and the brass construction coupled with the FPM seals has stood up beautifully to our rigorous cleaning cycles. For the price point, you really aren’t going to find a more reliable valve that offers this level of consistent shut-off and durability.”
Kamal Aris “Artisan and Numatics saved the day when our PXI Chassis and pneumatic line went down during a peak shift. We replaced our worn-out cylinders with Numatics 450 Series ISO models, and the difference in stroke velocity control was immediate. The technical support was excellent—they talked our guys through the installation over the phone, and the self-lubricating bearings in these cylinders have significantly reduced our weekly maintenance requirements.”
Numatics FAQ
How do I choose between a single-acting and a double-acting cylinder?
The choice depends on your application’s power requirements. Single-acting cylinders use air pressure to move in one direction and a built-in spring to return, making them ideal for simple tasks like clamping or positioning where power is only needed one way. Double-acting cylinders use compressed air for both the extend and retract strokes, providing more control and force for complex automation tasks.
What is the advantage of the Numatics “spool and sleeve” valve design?
This signature design features a hardened stainless steel spool and sleeve that “float” on a thin film of air. Because there are no dynamic rubber seals to wear out, these valves are incredibly durable and can withstand billions of cycles, even in harsh or non-lubricated environments where traditional soft-seal valves would fail.
Can I replace individual valves on a manifold without shutting down my entire system?
Yes, many Numatics valve series, such as the 501 and 503, offer a “pressure shut-off” or “sandwich” regulator option. This allows maintenance teams to isolate and replace a single valve station while the rest of the manifold remains pressurized, significantly reducing downtime in continuous manufacturing processes.
How often should I perform maintenance on my flow control valves?
While Numatics components are designed for high longevity, you should visually inspect them for leaks and debris every 3 to 6 months. It is highly recommended to install a high-quality Air Preparation (FRL) unit upstream to filter out moisture and contaminants, which are the leading causes of premature valve and seal failure.
What information is needed to correctly size a Numatics flow control valve?
To ensure the valve isn’t too small (restricting flow) or too large (wasting energy), you need to provide the required flow rate (Cv or SCFM), the inlet pressure, and the desired pressure drop across the valve. Additionally, consider the environmental conditions, such as temperature extremes or exposure to chemicals, to select the correct body and seal materials.
