The Copes-Vulcan DSCV is an angle style valve that combines pressure and temperature reduction. The DSCV is custom engineered for specific operating parameters. DSCV’s are generally used for applications where the valves typically remain closed for long periods of time to isolate steam flow.
The Copes-Vulcan PRDS Pressure Reducing Desuperheater is a single seat, angle style valve that combines pressure and temperature reduction in one compact solution.
The high pressure, high temperature vapor enters the main branch, is reduced in pressure and then coolant is introduced. The high velocities and turbulent flow conditions that are present immediately following the pressure reduction allow for rapid atomization and absorption of the coolant.
The PRDS Pressure Reducing Desuperheater is best suited to applications requiring continuous modulation.
