Flowserve Worcester Coated Valves Excel In Fishing Application
Refrigeration specialists, Grenco, which supplied freezing equipment for the 400-tonne Ocean Fresh fishing ship, selected Flowserve Worcester V-Flow control valves and Series 44 three-piece ball valves to control the critical supply of CO2 refrigerant to 36 Optimar vertical plate freezers. Caught by independent trawlers, herring, mackerel and sardines are deep frozen to -20°C and stored in these freezers prior to offloading.
"Due to the distances between offshore fisheries and onshore processors, and a highly demanding operating environment, only the largest vessels, supported by robust refrigeration systems, are economically viable," said Bob Bennett, marketing manager of Flowserve Flow Control UK. "Accordingly, we ensure our valves can withstand the harshest elements to meet the needs of our customers. The Flowserve valve configuration is coated with Surlon, making the units extremely hard-wearing, corrosion-resistant and impact-protected in demanding applications."
Worcester V-Flow valves offer the rangeability to provide fine control of the CO2 supply while still giving the tight shut-off associated with on/off valves. The valve design eliminated problems with CPR seats previously used as modulating valves, and was better able to handle pressure changes caused by temperature shifts during operation.
The valves, manufactured in Haywards Heath, were shipped to a Flowserve facility in Holland and assembled with Automax Supernova actuators and PMV positioners.
