Power stations and steam distribution systems depend upon robust and reliable flow control equipment. Global leader Celeros Flow Technology offers the Direct Steam Converting Valve – Steam Atomization (DSCV-SA) from Copes-Vulcan.
The Copes Vulcan DSCV-SA is suited to isolation of the steam flow in turbine bypass applications where valves remain closed for long periods of time. The valve offers operational reliability and minimizes potential risks associated with plant start-up, shutdown and turbine trips. The valve features a pilot plug design that achieves a very tight shut off in the closed position, using the full steam pressure to seal the plug. This load, combined with the actuator thrust, results in very high seat contact loads. This tight seal improves plant thermal efficiency, and also prevents leak induced ‘wire drawing’ damage across the valve seat which would otherwise result in frequent maintenance to repair or replace the seat.
The DSCV-SA is available in an almost infinite range of sizes as each valve is tailored to suit individual customer’s application requirements. The valve can be fully or split rated design and is available in standard, special or intermediate class. The DSCV-SA also comes equipped with modern ‘SMART’ instrumentation to suit all forms of communication protocol, fail safe requirements, responsiveness and accuracy.
