Spray valve for multiple coatings

The 784S-SS aseptic spray valve can dispense stent coatings, saline solutions, silicone oils, and other low- to medium-viscosity fluids used in medical-device production. The valve features an aseptic design with an entrapment free fluid-flow path. The 316L stainless-steel valve generates low volume, low pressure precision spray. Unlike standard spray nozzles, fluid goes through a 0.25-in. long disposable dispensing tip with a small (0.013 to 0.004 in.) internal diameter. Depending on tip diameter, fluid viscosity, and distance between the substrate and tip, the valve is capable of producing accurate, consistent spray patterns between 0.2 and 1.6 in. wide. Benefits in precision coating processes include greater process control, faster throughput, fewer rejects, and lower production costs.

Advanced fluid control goes modular

The Liquid Control PR70 meter, mix, and dispense system has a modular dispense valve that features multiple seat styles, an independent air cylinder, adjustable snuff- back control, and customized material mixing. An intuitive user interface provides simple system electronic controls with diagnostics and job data reporting, as well as easy, accurate shot-size programming and board-level diagnostics. Also available are a range of feed package options for agitation, heat, and degassing tasks.

Mini self-actuating valves

A line of miniature self-actuating valves and elastomeric valve components are for liquids and gases. The line includes one-way check valves, pressure-relief valves, access valves, and dispensing valves. Types include duckbill valves, umbrella and cross-slit valves, and valve balls in silicone, perfluor, and other elastomers. Applications include pumps, Y-sites, trocars, and haemostasis valves for catheter introducers. Standard valves, and custom development and prototyping are also available.

Pumphead simplifies tube changes

The 313D aseptic dental irrigation pumphead for continuous tubing is for dental applications requiring frequent tube changes, and flow rates from 0.25 to 3,000 ml/min. The fluid being pumped is contained in the USP Class VI-approved tubing, so cleaning is simply a matter of replacing a tube. The pumphead opens wide, and when closing, it clamps and stretches the tube optimum pumping performance. The pumps have no valves or seals and can run dry without damage. Options include an open indicator switch, fixed or variable tube clamps, private labeling, and custom colors. Extension heads allow stacking up to six pumpheads on a single drive. The 313D can be purchased as a pumphead only, and it can be customized to work with any pump grade tubing. Gear-motor drives are available in ac, dc, stepper motors, and brushless dc configurations. Like the company's other peristaltic pumps, the 313D is an inherent metering pump with repeatability at 99.5%.

Clean series pneumatic valves

The O-E series of pneumatic valves are ultrasonically cleaned for applications that use oxygen, air, and other inert gases. The miniature valves are available in 2-way or 3-way, normally closed, or fully ported. A patented valving system features an armature and spring that open and close the valve.

Small-footprint positive displacement technology

The RL series combines rotary lobe technology and efficiency in a small package, bringing the benefits of positive displacement technology to a 1.75-lb. unit 6 in. long. The small size is made possible through a patent-pending assembly that minimizes leak paths within the blower chamber. RL Series blowers provide high flow at low pressure and are for applications such as laboratory pressure and vacuum sources, fuel cells, laboratory pressure and vacuum sources, air samplers, gas boosting, and a variety of portable air-moving devices. Because rotary lobe blowers are contact-less with no internal wear surfaces, the RL Series generates little heat and provides long, service-free life. A 12V brushless-dc motor and precision permanently lubricated timing gears contribute to the product's long life. Despite its size, the RL Series blower delivers air flow up to 1.90 cfm (538 l/min), pressure to 2.0 psi (0.14 bar) and vacuum to 4.0 in. Hg (-135 mbar). It can be mounted vertically or horizontally, and it is equipped with standard 3/8-in. hose barns and a 6-in. wiring harness.
