New fluid power products shown at NDES

Design News editors encountered numerous new products at the 2002 National Design Engineering Show (NDES), some of which have medical applications.

A three-way isolation valve uses a soft disk within a diaphragm to create a tight seal. The Series 462 valve from ASCO Valve is made from inert materials, including PTFE, PEEK, and FFKM, which makes it suitable for use with the reagents and high-purity media found in analytical and medical applications.

A new vacuum generator from Clippard Instrument Laboratory combines a fully ported three-way valve with a venturi vacuum generator. It functions as a stand-alone device or as part of a pneumatic circuit. The valve uses microgap construction, giving a short stroke of the balanced spool. Applications for the vacuum generator include pick-and-place equipment, work-holding machines, and liquid draw-back circuits. Clippard Instrument Lab, www.clippard.com. Enter 602

Bird Precision introduced new 7.5-, 10-, 25-, 30-, 40-, and 50-micron medical gas orifices at NDES. The ruby and sapphire orifices control precise amounts of oxygen and other medical gases and fluids. The orifices have flow rates less than 1 cc/min and are chemically inert and wear resistant. Orifices come pre-mounted in stainless steel, brass, and plastic fittings with or without filters. Bird Precision, www.birdprecision.com. Enter 603

FESTO's new MHI miniature valve family for standard sub-base, sub-D connector, and PCB-mounted manifolds now includes a 10-mm, 10 liter/min unit. It is available with one of three electrical connection configurations. The first configuration is a direct plug-in style where a connection is made when the valve body is mounted to the sub-base. The other connectors plug into the rear or top of the coil housing. FESTO, www.festo-usa.com. Enter 604

Bimba Manufacturing Co. introduced an extruded linear thruster that combines a cylinder bore, switch mounting tracks, and guide shafts in a single package. The stainless-steel guide shafts resist corrosive damage from water in wash-down environments. The thruster body and tooling plate are made from anodized aluminum. Bimba, www.bimba.com. Enter 605

Dispensing valve

The DSVP12 liquid dispensing valve is gravity-fed and designed to dispense water-based solutions from non-pressurized tanks. Valve features Class F molded coils and an optional venting system. A conical diaphragm may contribute to a better performance by eliminating lime and mineral buildup on the valve seat. Applications include vending equipment, ice making machines, and water purification devices. Deltrol Controlswww.deltrol.com/controls. Enter 606

Submersible pump

Sub-Prime^(R) electric submersible GSP model pumps have maximum flow rates up to 5,000 gpm and up to 375-ft discharge heads. Engineered with single-phase motors to 6 horsepower and three-phase motors to 80 horsepower, the pumps operate in large dewatering applications. The pumps are made with rubber coated adjustable wear parts and a cast chromium steel impeller. Godwin Pumps, www.godwinpumps.com. Enter 607

Flow meter

The MuCell^(R) mass air flow meter is designed as an alternative to conventional solid molding for use in Delphi Automotive Systems' Energy & Chassis division. This two-component assembly is mated with a slide and latch system made of plastic. According to the company, the flow meter's injection molding process application reduces both warpage and machine size. Trexel Inc., www.trexel.com. Enter 608
