Mechanical flow meters

AutomationDirect | automationdirect.com

ProSense FG1 series mechanical variable area flow meters provide a visual indication of flow rate for water or petroleum-based fluids. These meters offer ±5% full-scale accuracy and a repeatability of ±1% — important for cyclical applications requiring consistent readings. Two adjustable flow limit pointers are available to provide preset indication of high, low or normal flow rates.

The flow meters are constructed of high-impact polysulfone plastic (body, piston, cone) with brass fittings ( 1 ⁄2 and 3 ⁄4 NPT models). FG1 series flow meters are available with 1 ⁄2, 3 ⁄4, or 1-in. NPT process connections and have easy-to-read flow scales in both gallons per minute (gpm) and liters per minute (lpm). Measurement ranges are from 0.25 - 2.5 gpm (1 to 10 lpm) to 4 - 28 gpm (20 to 100 lpm).

Oil-free scroll compressors

Ingersoll Rand | Ingersollrand.com

The W-series of oil-free scroll rotary air compressors generates Class 0 oil-free air quality and offers quiet operation. Scroll compressors meet a broad spectrum of oil-free needs for commercial applications that require contamination-free air, low maintenance, and a smaller footprint.

The W-series scroll compressors use an orbital wheel singlestage technology. Two interlacing spiral scrolls pump, compress, and pressurize the air. One scroll remains in a fixed position, while the other scroll orbits around it without rotating. The motion traps the air in the pockets between the two scrolls and pushes the air towards the center. As the air moves closer to the center, the pockets shrink, and the air compresses.

This unique design creates air completely free of oil — there is no oil in the compressor, air, or condensate at all. The scroll compressors have a simple tip seal design with no metal-to-metal contact eliminating metal friction and the need for lubrication while maintaining sealing performance and saving energy.

Open-loop variable-displacement pump

Oilgear | oilgear.com

The XD5 hydraulic pump is the first model of the XD series designed specifically to meet the demands of mobile markets. The XD5 is applicable in on and off-highway equipment such as mining trucks, haulers and dozers, excavators, and trenchers. It can also be used in on-highway vehicles such as refuge trucks, snowplows, and any Class 8 service truck.

The XD5 is an open-loop axial-piston hydraulic pump with almost instantaneous response to system commands through a high-response, three-way, direct-acting control. The new pump is significantly smaller and lighter than its comparable pump line, the PVG series.

The heart of all Oilgear pumps, including the XD5, is its proprietary Hard-On- Hard Technology . This process enables Oilgear pumps to withstand continuous use in medium to heavy duty cycles mitigating contamination risks which can lead to premature or increased maintenance and costly equipment downtime.

The XD5 is the first of what will be five models in the XD series, ranging from 45 to 130 cm 3 .

Miniature valve controls ventilator flow

Parker Hannifin | parker.com

The Parker LM-Pro miniature proportional valve uses a linear motor actuation technology to enable flow up to 540 slpm in a very compact and energy-efficient package. A critical feature of the LM-Pro valve is the valve’s linear motor actuation technology that provides exceptional resolution over a longer stroke and lower power consumption than traditional solenoid or voice coil actuation designs. With a linear controllable flow range from 0.5 to 540 slpm, pressure capability up to 100 psi (6.9 bar) and typical power consumption of less than 2 W, the LM-Pro valve enables precise flow control throughout the full performance range of the valve.

The LM-Pro valve allows for simple, closed-loop feedback, giving the customer precise pressure or flow control. This ensures accurate and safe delivery of precise gases to patients, from neonates to adults. Typical applications will require less than 2 W of power, giving users longer battery life or the ability to take advantage of a smaller battery to save size and weight. Typical hysteresis of <10% (full scale), coupled with a fast response time of <20 msec (full cycle), provides excellent low and high flow rate and precision control proportional valve performance.

Fail-operational steer-by-wire valve for off-highway machinery

Eaton | eaton.com

The SBX advanced steering valve is a fail-operational steer-by-wire valve for off-highway machinery. The compact, modular SBX valve increases machine flexibility and intelligence by enabling machine designers to tailor steering performance to the operator’s preferences and operating conditions.

The SBX advanced steering valve was designed for use in a fully electronically controlled steer-by-wire system. Fail-operational functionality is achieved by mounting the SBX valve to a secondary electrohydraulic valve or manifold. Because there’s no hydraulic connection to the cab, the valve can be remotely mounted, allowing for more flexible machine design and reduced cab noise. The valve can be paired with the OEM’s machine control system or with an Eaton controller, further increasing design flexibility.

The SBX advanced steering valve is SIL 2 and PLd capable, which enables OEMs to develop machinery that complies with international standards. Designed for equipment in the construction, agriculture, material handling, and forestry industries, the valve is suitable for use with systems incorporating multiple steering wheels or alternative devices, such as a joystick or lever.

The mobile cutting machines which are, in comparison with the traditional circular cutters, just slightly bigger and negligibly heavier, are fixed at the workplace, i.e., the “cutting table,” using just two screws fast and safely. Both “small” cutting machines from UNIFLEX, the EM 1 for hoses up to 5 ⁄8-in. and the EM 1S for hoses up to 1¼ in. in diameter, are available in two motor versions (230 and 110 V, 50/60 Hz 1 Phase) for trouble-free use worldwide. Both devices are easily operated and are supplied with a manufacturer’s warranty of two years and are EC compliant.

Valve option for CAN bus

HAWE North | America hawe.com

PSL series of directional spool valves have a modular design that combines all actuation functions in one control block, making it individually adaptable to specific needs.

The capabilities of these proportionaldirectional valves have now been extended, thanks to the new actuation option: CAN Lite. By switching from a valve controlled by pulse width modulation to CAN bus, the valves can be addressed precisely and functional parameters easily adjusted. The start and end position of the spool valve are already preset on delivery for easy commissioning.

The hysteresis typical for spool valves during operation is very low with PSL-CAN Lite. The entire valve bank connects to the machine’s bus system with only one connector plug. This minimizes cabling effort and shortens commissioning time.

Type PSL directional spool valves generally have operating pressures up to 420 bar (6,091 psi) and a flow rate range from 1 to 1000 lpm (0.26 to 264 gpm) available in four sizes. The different sizes can be combined in a valve bank. If only the size required for the respective individual function is used in the valve bank, weight is reduced and fine control is further improved.
