Oventrop valves help bank keep rates steady

11 June, 2007

Maintaining constant preset flow to terminal devices in the data halls of a leading bank in the south west of England are Oventrop Hydromat Q flow-regulating valves.

Oventrop Hydromat Q automatic flow-regulating valves have been installed to serve mission-critical blade-server racks as part of the refurbishment of mechanical and electrical infrastructure systems of data halls of a leading bank. It was essential that the chilled water could be set for various flow rates to match the actual cooling requirements of cabinets. As equipment was gradually installed and brought on line, the installation needed to self balance. Hydromat Q valves are proportional regulators that work without auxiliary energy in heating or chilled-water systems to maintain a constant flow within a preset proportional band. To achieve the set nominal flow, a minimum pressure differential of about 200 bar is needed with the required flow rate set using the scale on the valve. The diaphragm will keep the differential pressure constant by moving the valve disc to limit the flow at the preset value. The bank’s system is based on two screw-compressor chiller with free-cooling coils. Oventrop commissioning valves are used throughout to balance the system. Variable-speed pumps circulate chilled water to the cabinets, with buffer tanks to provide a thermal store. The project also includes Oventrop cast-iron and bronze commissioning sets, metering stations, lugged butterfly, gas and ball valves and bronze strainers. Capita Symonds was consulting engineer, and the mechanical contractor was Interserve Engineering.
