AIR FILTERS

Ultra-thin

Measuring less than .25-inch thick, the ultra-thin air filters reportedly meet the strict filtration performance and flammability requirements of Telcordia, NEBS, CE, and UL. It is designed for electronics enclosures with limited space; specialized Quadrafoam media is used in roll-formed, aluminum-framed filter assemblies to fit limited-space environments. Frame options include edge-to-edge design constructed with less intrusive channel housings, reportedly maximizing the flow of clean cooling air along interior walls of the chassis.

FLOWMETERS

For custody transfer

The company's API Series turbine flowmeters for custody transfer are designed for light petroleum products. They are reportedly approved over a flow range of 10:1 and have type approval from Measurement Canada, which puts the product in a class with only one other vendor having type approval over this range, according to the company. The product provides users with linearities of plus or minus 0.02 percent. Hoffer Flow Controlshttp://rbi.ims.ca/3858-619

MODULAR INSTRUMENTATION SYSTEM

Includes all components needed

The Kenmac series modular 85 system is a modular instrumentation interface and mounting system. It reportedly includes all of the components needed to put a transmitter into service.

PUMP DISPENSER

Uses peristaltic pump technology

Providing "volumetric" dispensing of low-viscosity materials such as cyanoacrylates, oils, and solvents without the need for compressed air, the PPD-130 peristaltic pump dispenser dispenses material directly from its original packaging. According to the company, this reduces the risk of material contamination and operator contact by eliminating the need to transfer the material from its original packaging. Dispensed amounts can reportedly be controlled manually or with the built-in timer. I&J Fisnarhttp://rbi.ims.ca/3858-621

FLOW SWITCHES

With solid state relay outputs

The 501 flow-switch is engineered to offer a solid-state relay output indicated flow above or below a selected set point. It is designed for users who require alarms for low- or no-flow conditions, excessive flow, or intermittent flow rates. They are available in plastic or stainless steel construction, and feature solid state relay outputs with setpoints as low as 13 mLpm. Units may be used with pressures up to 500 psig, according to the company. McMillan Co.http://rbi.ims.ca/3858-622

NYLON CHECK VALVE

Two-piece, glass-reinforced

The company's new check valve design reportedly improves oil flow control in marine and industrial engines, while reducing part weight and cost. The two-piece oil filter check valve is made of glass-reinforced Nylon and is designed to allow switching between two oil filters during regular engine operation. The two molded components incorporate special rubber seals that are chemically and mechanically bonded to each end of the valve, preventing oil flow to one filter during operation while allowing oil flow to the second filter.

PIEZOELECTRIC PUMP

Miniature in size

The DTI-200-12P and DTI-200-12A models of miniature piezoelectric pumps feature technology that solves size problems, power consumption, noise, and reliability for a range of liquid and gas pumping applications. The pumps operate when the bonded piezoelectric crystals are stressed and distorted by an electric field, which causes the diaphragm to flex and two check valves to respond to this flexing, creating a pumping action. Electromagnetic noise is eliminated because there are no electric motors. Both pumps have a pump life of 10,000 hrs and can deliver flow rates of up to 200 ml/min for water and 7.5 SCFH for air.

GAS METERING VALVE

Direct-acting

The company's gas metering valve is designed to be a direct-acting proportional SERVOID(R) valve, providing linear proportional control of the metering orifice, which yields linear proportional flow. The product features a suspended-armature design that is reportedly reliable and results in low hysteresis. The valve can be calibrated for use at supply pressures up to 100 psig, and flow rates up to 1,500 SCFH of natural gas at a 10-psid pressure drop are possible, according to the company.

O-RING

Trapezoidal-shaped

The Trap-Seal(TM) from Parker Hannifin Corp. provides improved seal reliability by reducing the possibility of the O-ring popping out of the O-ring face seal (ORFS) groove. Featuring greater seal retention, reduced risk of seal damage and leakage, and a smoother pre-assembly process, the Trap-Seal is designed to stay securely lodged under the ORFS groove lip. The Trap-Seal is also interchangeable with the standard O-ring used in half-dovetail grooves, making seal replacement quick and easy. Parker Hannifinhttp://rbi.ims.ca/3858-634
