and a span of 1:10. The LFC is based on the successfully proven and tested software, hardware and mechanics of the MFC series. Thanks to its compact design, the controller can be installed in difficult locations, such as directly behind angled piping. Due to its fast and accurate flow rate measurement, the LFC can be used in a large number of industrial applications such as process engineering, packaging, surface finishing, coating, filling or machine tool construction. Some examples of potential applications are: heat treatment by carburisation or endogas generators; the testing of fuel cells; the coating of surfaces; and the cooling of machine tools
compensating seals and a narrow profile. Using a patented Vortex design, the company says that the Orifice Gate valve offers significant advantages over traditional knife gates and butterfly valves. “Other gate valves, knife gates, slide gates, and butterfly
valves rely on soft rubber seals that erode away or tear when handling dry bulk material. The Vortex Quantum series Orifice Gate valve eliminates these problems by using ‘live loaded’ hard polymer seals,” it says. Oliver Twinsafe is set to increase the efficiency of its double
block and bleed valve production having ordered a bespoke test rig from Ventil Test Equipment in Holland. “The state-of-the-art computerised facility boasts a 275 t
clamping load and has been designed specifically for Oliver’s double block and bleed product. Ventil have been fantastic,” said engineering director Craig Furnival. “From their first site visit to the correspondence we’ve had during the development of the rig they’ve been extremely helpful.” “These rigs are popular for testing single isolate valves

Burkert says the big advantage of the LFC is that it is a one-stop system solution combining reliability and functionality with a truly convincing cost-performance ratio. Vortex has launched its new Quantum series Orifice Gate.
It has fewer parts than the original Vortex Orifice Gate, along with other benefits including weather resistance, superior sealing capabilities, fast and easy maintenance, self-cleaning, wear
but DBB valves have more seats so the software that runs the test is unique to Twinsafe. The size of our valves was also a consideration as our clamping load requirements are higher than that offered by Ventil’s standard range,” he added. The fully automated rig will run through Oliver Twinsafe’s
entire test cycle, hydrostatic and gas, at the push of a button and utilises a vacuum fill system which effectively sucks water into the valve body rather than pumping water into the cavities. “If we pump water in then there are often voids which trap
air. If we are populating a vacuum then we know that every space will be filled,” added Furnival. The rig will accommodate valves with bore sizes from 2-in
to 14-in including 8-in 2500lb, 12-in 1500lb and 14-in 600lb pressure classes. “This rig offers a full digital reporting service so not only will
it significantly increase our output, it will also offer another level of traceability for our customers,” concluded Furnival. n
Reducing contamination in bearings

Bearing Isolator technology, originally developed by Inpro/Seal in 1977, has been an integral part of increasing the mean time between failure (MTBF) and improving the reliability of a variety of rotating equipment.
The Inpro/Seal Bearing Isolator is a two part dynamic seal consisting of a stator, most commonly press-fitted into the bearing housing, and a rotor attached to the shaft. The rotor and stator join together to form a non-contacting compound labyrinth seal with no wearing parts. It protects in two ways: bearing lubricant is captured in the inner portion of the labyrinth and flows back to the bearing housing; outside

s end-users of rotating equipment seek to extend the life of these applications, increasing emphasis
contamination attempting to enter the bearing housing is captured in the outer labyrinth paths and expelled through a port in the rotor by centrifugal force and gravity.
The Bearing Isolator was invented to replace lip seals as a sealing solution in industrial process equipment, such as pumps, motors, gearboxes, pillow blocks and other types of rotating equipment. Because of their contacting design, friction against the shaft limits the life span of lip seals to about 3000 hours. Alternatively, an Inpro/ Seal Bearing Isolator lacks any wearing parts thereby sealing the bearing for the life of the equipment. n
