The Old Timer of Royal Oak, Mich., learned that you have to consider the system — rather than a single component — during both design and troubleshooting.

Pneumatic valves

Thu, 28 Mar 2013 20:09:00 +0000

Low-power Isonic V2 direct-acting, solenoid-operated valves are available in normally-open and normally-closed configurations. They can be used to control vacuum and positive pressures at flow rates up to 0.05 CV. Molded from high-performance thermoplastic, they provide heat, impact and moisture resistance. It reduces power consumption by 60%, extending the life of battery-operated equipment and lowering costs.

High-flow electronic valves

Clippard Minimatic Electronic valves and manifolds provide a complete system for efficient interface with electric and electronic circuits for many applications. They provide an air flow of 1.4 scfm @ 100 psig, more than twice the flow of Clippard’s trusted EC/EV/ET valve series. Optional 1.1 scfm @ 50 psig and 0.95 scfm @ 25 psig flow models are also available.

Prospector poppet valve has been expanded to operate in extremely low temperatures, from –40°C (–40°F) to 60°C (140°F). Its high flow and short stroke result in fast response times. It is available in air pilot or solenoid pilot design in a wide range of voltages.

Valves keep workers out of harm’s way

By Eric Cummings, Ross Controls

When safety matters most, monitored redundant valves are best.

Keeping workers safe in a manufacturing environment demands a healthy respect for the sometimes dangerous interactions between humans and machinery. Fortunately, when it comes to fluid-power systems, once-simple components such as safety-related valves have evolved into highly sophisticated devices.

Novel valve boosts pneumatics efficiency

Compact, lightweight valve mounts close to actuators.

Energy-efficient pneumatic circuit design often involves mounting valves as close as possible to the actuator. Reducing the length of tubing between a valve and actuator — and with it the volume of compressed air required for each actuator cycle — can cut compressed air consumption by as much as 20%.

High-flow pneumatic filters

The 201-9202 series of high-flow filters from Monnier are available in particulate (3 µm element) or coalescing (0.01 µm) styles. They come with 3-in. NPT ports and NPT, BSPT and BSPP threads and are rated for flows of 1200 scfm at 100 psig with a 1.0 psig ∆P. Housing is heavy-duty cast aluminum.

Vacuum-cup check valve

Mon, 14 Jan 2013 18:06:00 +0000

The piSave sense flow control/check valve for vacuum cups is used for object sensing on flexible handling devices using a centralized vacuum pump. It works in any orientation, even upside down. It is dirt tolerant and increases vacuum flow through the valve when vacuum level decreases, therefore retaining high lifting force in cups that are in contact with product. Valve allows several vacuum cups to miss (or partly miss) sheets/objects and still maintain system vacuum level and offer a fast-release or blowoff.

Electronic valves

Analytical series electronic valves are available in 2- or 3-way, normally-closed or fully ported designs. “A-E” pneumatic valves consume only 0.67 W of power from 6-, 12-, or 24-Vdc source, with a response time of 5 to 10 msec. Special materials, manufacturing, and assembly processes make this valve suitable for applications where internal cleanliness, bubble-tight
