DVD Check Valve Suitable for HVAC Applications

DVD Valves has launched the DVD swing check valve with dashpot, for use in applications or projects that have a risk of surge, such as heating, ventilation and air-conditioning (HVAC) systems. The company claimed that if an application has a risk of surge, it is not wise to use standard swing check valves. This is because in case of a surge, water columns that are flowing back can hit the check valve fast, which can burst down the entire system.

In the DVD check valve, the dashpot makes the door of the valve close very quickly until some critical point, leaving a small gap for some water to pass through the valve, and then slowly seals the door tight. The dashpot acts like a cushion in case the door shuts down suddenly.

Using this solution, a small amount of water, which does no harm to the system, is let through the valve, dropping the surge. The check valve seals tight when surge conditions disappear. A key application for the product is HVAC systems. In addition to surge and water …

The device's proprietary auto-polarity topology allows it to generate usable power from input voltages as low as +/-30mV, enabling temperature differences as low as +/-1C to be harvested in lieu of traditional battery power. This makes it ideal for energy-harvesting applications in which the input voltage polarity is unknown or is subject to reversal.

The LTC3109 uses two standard compact step-up transformers to provide a complete power-management solution. Its 2.2V LDO can power an external microcontroller and its main output is pin selectable to one of four (2.35, 3.3, 4.1 or 5V) fixed voltages to power a sensor, data-acquisition circuits and/or a wireless transmitter. A second switched output can be enabled by the host in order to power devices that do not have a micropower shutdown c…

De-Scaling Units Solve Mine Pipe Fouling Problem

Environmental Concept Services has revealed that its Enigma electronic de-scaling units have been installed on feed pipes at the Neves-Corvo copper mine to solve hard-water problems. The ore treatment is carried out by conventional crushing, flotation, grinding, thickening and filtration processes. The copper plant treats up to 2.2 million tonnes of ore each year, producing high-grade copper concentrate mainly for the export market.

As part of the process, Somincor Mining Company - which operates the mine - need to store tailings pyrites in a 190-hectare dam, 3km from the mine itself and water from the dam is used in the industrial process. In order to balance the very high pH levels in the dam, between 10 and 20 tonnes of lime needs to be introduced into the system each day. As a result, three pipes of between 35cm and 40cm diameter feeding the industrial tank required constant chemical and mechanical cleaning.

Various methods of cleaning had been tried, including injecting CO2 direc…

Fortress Simplifies Switchgear Interlocking

Fortress Interlocks has explained how it is able to simplify switchgear interlocking to protect personnel and plant in distribution systems. The company has extensive experience in ensuring that earth/ground switches cannot be closed on live busbars and that isolation procedures are strictly adhered to. Fortress recognises that creating a simple interlocking scheme is critical - no one wants to work with a system that is too complex to follow; operators will simply look for shortcuts.

In many power distribution projects, key interlocks are often left to the last minute to source and fit, which can result in confusion on site during final commissioning. Larger projects also have the added complication of multiple switchgear suppliers who, unless key interlocks are specified, often supply their standard product, which can be awkward and unsuitable. Involving Fortress in the initial stages of designing the interlocking system saves time and money via custom-built key interlock systems th…
