The modular 27R Precision regulator replaces current 27R models. A new design provides greater responsiveness, high repeatability, precise adjustment sensitivity, and multiple port options and modular configurations. It features a brass poppet, nitrile diaphragm and seals, and steel springs. The regulator has a flow rate of 25 SCFM at 100 psig inlet.

Threaded Line Vac air-operated conveyors convert ordinary pipe into a conveying system for parts, scrap, and other bulk materials. By attaching the unit to plumbing pipe couplers, it is possible to build a complete system. The device ejects a small amount of compressed air to produce a vacuum on one end with high output flows on the other end. Construction is aluminum.

The NIMIX mixing system features a totally enclosed, low-shear mixing process that imparts strong bottom-to-top circulation and handles both Newtonian and non-Newtonian fluids, as well as suspended solids. Based upon a fluid diode principle, the system uses a reciprocating diaphragm that causes flow to move in and out of a diaphragm cavity. The diode plate above the diaphragm produces preferential flow depending on direction, causing liquid to move smoothly upward at the center and back down at the wall.
High-flow, single-stage servovalve is reportedly a cost-effective solution for closed-loop applications up to 48 gpm. The servovalve uses a standard NG10 mounting pattern and utilizes integrated electronics to monitor spool position and reduce the valve's hysteresis to less than 0.3%. The product has a low sensitivity to contamination, performance that is independent of pilot pressure, and a leakage flow of less than 0.045 gpm.

New flange-mounted drop-in hydraulic solenoid valves offer integral waterproof coils for 12 or 24V dc operation, several push-on termination options, and rugged metal covers. The model SV98-T39 is a direct acting, balanced-spool, 2-position, 3-way directional control valve designed for low-pressure applications such as pilot systems or power shift transmission control. Other models are in development including a 4-way, proportional pressure reduc-ing valve, and a ball-type 3-way directional valve.

Strain relief fitting
Liquid-tight, nickel-plated cord grips with EMI protection work with braided and foil shielded cables. Installation requires stripping the cable, inserting it into the fitting, and tightening. A serrated nickel-plated nut assures a positive ground to the mounting surface. The fittings can handle temperatures from -40 to 212F and pressure up to 150 psig. Its splines allow for a substantial cable range for each of the 10 basic sizes and cable diameters from 1/16 to 1.75 inch.
These brass, bronze, and 316 stainless-steel valves are engineered for fluid control applications such as corrosive fluids, air, steam, and vacuum. Features include: compact design, working pressures up to 600 psig, waterhammer free, and a 4 to 20 mA electrical output.

The Max-Flow gas filter provides sterile gas delivery in healthcare applications such as insufflation, oxygen concentration, vacuum protection, and ventilation. The filter's housing design, large port sizes, and membrane minimize gas flow resistance. A universal 15/22-mm connector, per ISO 5356, allows for an easy and air tight gas supply connection. Multiple medias are available to remove bacteria, viruses, and particles and retain liquids. The filter is available in a range of connector and color options.

New push-to-connect air mufflers are injection molded and constructed of glass-filled polypropylene. These mufflers have a unique push-in stem design that permits installation or removal in seconds. This product series may be used on the manufacturer's Isonic(R) valve line or with virtually any directional control valve or manifold. The component is offered in 6-mm, 10-mm, .25-inch, and 3/8-inch sizes to fit different collets.

An oil-free pump line combines a patented, structured diaphragm and multi-port valve technologies with electronically commutated dc motors for compact performance and efficiency. Pumps range from 0.1 to 30 liters/min and feature end-vacuums to &0.375 torr using up to four stages. A variety of performance enhancements, system integration options, and chemical-resistant PTFE versions are available. The pumps supply low EMI and RFI levels, which is a requirement of many battery-operated, continuous-duty analyzers.

Large bore connectors assist in drainage and other appli-cations requiring high fluid flow rates. These fittings are for use on tubing with 3/16- to 5/16-inch ID and feature a single-barb design without a parting line on critical sealing surfaces for secure, solvent-free connections. Molded in medical-grade Class VI Terlux(R) ABS, the connectors may be Gamma and EtO sterilized.

Users can specify the Cube Line(TM) 10 pneumatic directional control valves in banks that are factory pre-wired and tested, reducing design, purchasing, and installation time. Because the valves plug in to the manifold, making electrical and air connection simultaneously, maintenance is simplified. Valves feature flows up to 0.3 CV, have a standard multi-pin D-Sub connector, and offer an option to add a serial link communication module.

Smartflow(R) manifolds facilitate routing and metering of multiple flow streams. The manifold material is corrosion-resistant 304 stainless steel and the unit's standard inlet sizes are 1- and 1.50-inch NPT. Its maximum ratings include 250F for temperature and 125 psig for use with air or inert gas and 250 psig for use with liquids such as hydraulic oil, water, or benign fluids. Mounting options encompass in-line, bulkhead, pipe stanchion, or rack mount.
