24 WET NEWS AUGUST 2014 WHAT'S NEW! Portable valve actuator Operating valves in water and wastewater installations can be a laborious and dangerous task, especially if the valves are used infrequently, corroded or have varying torque requirements. Smith Flow Control's EasiDrive portable valve actuator is designed speciƒ cally for these scenarios, by allowing operatives to operate valves without One-piece Monoblock removes the risk ACO has launched an alternative to the traditional two-part channel and grating system – the MultiDrain Monoblock PD100D.ˆ Part of the MultiDrain family, the one-piece system removes any risks associated with dislodged or stolen gratings, thanks to its anti-theft design, as well as being extremely robust, easy to maintain and low cost.ˆ The Monoblock PD100D has been speciƒ cally developed to meet the demands of both contractors and end clients. It is manufactured from Vienite, ACO's high performance recycled material that is four times stronger than traditional concrete.ˆ ˆ Pumps for volatile environments Xylem has expanded its range of Lowara vertical multi-stage pumps with the launch of a new high e' ciency model, the e-SV ATEX, for use in potentially volatile environ- ments. First introduced in 2010, the Lowara e-SV range has become synonymous with high quality and outstanding performance due to its innovative hydraulic design and energy e' cient properties. The latest variant is no di' erent, and is able to deliver a flow rate of up to 160m³/h, with a head of up to 330m in the standard conƒ guration. The e-SV ATEX draws its name from the French title of the EU's 94/9/EC, known as ATEX 95, Directive on equipment and protective systems intended for use in a potentially the need for dedicated valve actuators. With the EasiDrive the operator has absolute control. One person can e' ciently drive multiple valves with a single tool, reducing fatigue and risk of injury and resulting in major cost and time savings. A key feature is a 'reaction kit' that prevents a torque kickback, ensuring valve movement is always fully controlled and preventing operator injury and fatigue. In addition, the variable torque output feature, which prevents excessive torque being applied, ensures proper and safe valve operation at all times. www. smithflowcontrol.com Tel: 01376 517901 The lightweight nature of Monoblock PD100D – all channel units weigh less than 25kg – makes it very easy to install and results in a high daily installation rate.ˆ For maintenance, access is through lockable rodding access points, sumps and gully units, allowing the system to be simply and e' ciently cleaned by standard jetting equipment. ˆ The system's 0.5m long channel units form the core of the range: these are available in ƒ ve constant depths from heights of 128mm (ideal where installation depths are restricted) to 353mm (for maximum hydraulic performance).ˆ The 100mm wide channels are available as standard in black, typically complementing asphalt pavements, or in natural or grey colour options.ˆ For even more flexibility, a number of design conƒ gurations including constant depth and step fall, in addition to T and L junctions are available. www. aco.co.uk Tel: 01462 816666 explosive atmosphere in commercial and industrial applications. It is capable of handling liquids of up to 104°C as standard, however versions are available on request which are can cope with tempera- tures of up to 194°C. www. Xyleminc.com Tel: 0115 940 0111 Clamping levers for swi fastening WDS has released a new range of CAM levers that allow for quick fastening and unfastening without the need for additional tools. The high quality CAM levers are available in a choice of stainless steel or glass reinforced polystyrene (GRP) construction and a range of sizes to suit individual applications. CAM levers are suitable for applications that require a high clamping force that can be quickly applied and released. The lever is initially tightened like a traditional screwed fastener, but the ƒ nal clamping force is applied by a push down lever which turns a CAM to apply the clamping force. The WDS range allows the application of clamping forces of between 2.5kN and 8kN without the use of any tools. Di' erent sizes are available with reduced proƒ les for applications with less space, or longer handle options can be purchased to allow the clamping force to be applied with greater ease. The entire range beneƒ ts from tough glass reinforced polystyrene (GRP) thrust washers to o' er a secure and long lasting clamping force when the handle is pushed down and the CAM is activated. The levers are available with polished stainless steel handles and stainless steel pin, stud and washer; or black GRP handles with a choice between steel or stainless steel pin, stud and washer. The company also has a new product catalogue available, which includes the new clamping levers. Also, 2D and 3D product models are available to download online in CAD compatible formats. www. wdsltd.co.uk Tel: 0113 2909852 Pegasus+ controls PRVs HWM has a new electronic controller available for pressure reducing valves (PRVs). Pegasus+ enables detailed multi-point PRV control without a flowmeter, either by flow or by time, together with sophisticated closed loop control. The controller permits immediate control of pressure within a distribution network, and automatically adapts to network changes and events by analysing data from up to three critical points (CPs). By controlling PRV output pressure, Pegasus+ maintains CP targets deƒ ned in terms of time, flow or a combination of the two. Networks can be optimised to reflect changing demand throughout the day or week. In extreme or emergency situations, a latching solenoid output enables valves to be fully opened or closed according to controller settings. Bidirectional GPRS telemetry can be used to trigger alarms or remotely control the valve. Pegasus+ also features a secondary channel for fast logging down to one-second intervals. www. hwm-water.com Tel: 01633 489 479 Air / gas flow meter gets approvals The future-ready ST100 Series Thermal Mass Air / Gas Flow Meter from Fluid Components International has received ATEX and IECEx approvals. These approvals specify design criteria for flow meters and other electrically- powered instruments for use in areas where combustible gases may be present. The ST100 Series Flow Meter sets a new industry benchmark in process and plant air / gas flow measurement, o' ering the most feature-rich and function-rich electronics available. The ST100's performance delivers unsurpassed adaptability and value to meet plant gas flow measurement applications for today and tomorrow. The user-friendly ST100 stores up to ƒ ve unique calibration groups to accommodate broad flow ranges, di' ering mixtures of the same gas and multiple gases, and obtains up to 1000:1 turndown. An optional, patent-pending SpectraCal Gas Equivalency calibration method lets users select and switch between ten common gases. Also standard is an on-board data logger with an easily accessible, removable 2GB micro-SD memory card capable of storing 21 million readings. The ST100 is one of the ƒ rst thermal flow meters to o' er three di' erent types of flow sensors to best match user applications. The fast-response FPC-style is a fast response features an integral flow conditioner and protective shroud optimized for compressed air and clean gas applications. It can be calibrated to measure virtually any process gas, including wet gas, mixed gases and dirty gases. www. fluidcomponents.com Tel: +1 800 854 1993 Ridgistorm- XL keeps flooding at bay Polypipe's Ridgistorm-XL large diameter piping system has been used as part of a flood alleviation scheme for Dŵr Cymru Welsh Water. The Gulls Way capital works scheme in Heswall, Wirral, required combined sewer improvements along a residential street where the existing 450mm concrete sewer had insu' cient capacity to cope with high volumes of rainfall, causing the surrounding road and a number of properties to flood during storm events. Working with Welsh Water, consultant engineer AECOM, main contractor Costain and ground- worker Mulcair from an early design stage, Polypipe supplied a fully engineered Ridgistorm-XL attenuation system comprising a dual pipe run to provide an additional 360m 3 of storage. As well as providing Ridgistorm-XL pipes in 900mm diameters, Polypipe also utilised its large diameter piping and its ability to prefabricate structural components to create a number of 1,500mm chambers and modular H access manholes to sit between the pipe runs. www. polypipe.com/wms Tel: 01509 615100 Rugged notebook gets more processing power Getac has upgraded the processing power of its fully rugged notebook.
