performance valves are suitable for applications that require very precise control of air and neutral gases for medical or industrial applications. Preciflow-IPC 2-way proportional valves are constructed from high performance materials, including stainless steel for the valve seat and body and FPM for the diaphragm and seals. The design of the valve enables precise control by using flat spring technology to keep the core in...

Gems Sensors and Controls has introduced the RFO RotorFlow Series of fluid flow sensors for flow rate monitoring and metering applications. The sensors provide a pulsed dc voltage output that is proportional to the rate of flow. The 4.5 to 24Vdc pulsed output is easily integrated into most digital logic units. RotorFlow features a highly visible paddlewheel that provides immediate visual confirmation that fluids are moving. As...

Wind turbine gearbox dryer protects lubrication (09/07/2010)
Brownell has introduced a self reactivating dry air breather to prevent contamination of gearbox lubricating oil by water and condensation. The REGEN8 has a robust all weather construction and features automatic process control, including a telemetry option for remote monitoring and control. Many lubricating oils have a water vapour adsorption characteristic. Commercially available lubricating oils are delivered by most manufacturers with low residual water content. Maintaining this...

AxFlow reduces compressed air costs for AODD pumps (05/07/2010)
AxFlow is now offering a novel approach to reducing air consumption for larger size air-operated double diaphragm (AODD) pumps. Using the MizAir, it is possible to reduce air consumption by up to 50% with minimal loss of fluid flow. Designed for close-coupling to the pump, MizAir requires just a 24Vdc power supply. A self-powered ATEX version is to be introduced later in 2010. The microprocessor...
Metal faced seals can be customised to meet specific application requirements (01/07/2010)
Eriks subsidiary, Pioneer Weston has introduced a range of competitively priced metal faced seals for tough rotary applications. There's a broad mix of standard sizes and dimensions to fit the widest range of applications; pairs of seals from 38mm ID to 1.5m ID are already available, with further special variations being added as new applications are identified. Metal faced seals offer bearing protection and lubricant retention on...
Compact spiral hose offers long service life (28/06/2010)
Parker Hannifin has introduced a flexible, compact spiral hose that offers long service life in both stationary and mobile industrial machinery. With a pressure performance of 5,000 (787TC) and 6,000psi (797TC), the new compact spiral delivers two million impulse cycles – two times the ISO 18752-DC standard and four times the SAE requirement. This translates to a significantly longer service life in nearly all applications, particularly in those where many repeat...
White paper proves superior energy efficiency of screw technology for air blowers (28/06/2010)
The main conclusion of a technical white paper published by the Atlas Copco oil-free air division, which explains the differences between screw technology and the traditional Roots type lobe technology, is that the introduction of air blowers using internal compression instead of external compression sets a new standard for energy efficiency in the low-pressure market. The on-average 30 percent more energy efficient screw technology...
Air nozzles blow hard but have 'soft' noses (28/06/2010)
The new Exair PEEK Super air nozzles, which are available in the UK from from Good Hand, deliver strong blowing force while providing non-marring protection should the air nozzle come into contact with other surfaces. The engineered thermoplastic construction offers excellent resistance to chemicals, fatigue, and temperatures up to 160°C. At 80psig, the sound level is under 76dBA, which meets recognised noise requirements. Safe...
‘Mould-in-place’ sets a new standard for automotive gaskets (28/06/2010)
A new mould-in-place process for the automotive industry enables rapid injection moulding of liquid, high-performance sealing materials that cure rapidly on exposure to UV light. The technique enables components to be manufactured with integrated polyacrylate gaskets, eliminating some of the energy intensive process steps associated with form-in-place silicon rubber gaskets Automatically dispensed liquid gaskets play a key role in modern vehicle manufacturing, a success...
Liquid pumps for specialist instrument applications (28/06/2010)
Nitto Kohki reports growing customer interest following the introduction of two liquid pumps, the Bimore Piezo and DPE diaphragm ranges. With Bimor Piezo, flow is created by a ‘bimorph’, two parallel piezoelectric wafers that expand and contract according to the applied voltage. The system operates with extremely low current (typically 14mA), has very low EM emissions and offers low vibration, low noise and minimal flow fluctuations. This lightweight unit pumps...
George Fischer presents a new generation of diaphragm valves (24/06/2010)
A new range of diaphragm valves from George Fischer Piping System features a central union nut instead of the usual four metal screws. This non-corrosive connection is characterised by homogeneous temperature behaviour, an even surface pressure and high pressure rating up to 16 bar. The optimised flow geometry delivers double the flow rate with the same pressure loss as the previous version, and almost linear flow characteristics. ...
