Our combine PRDS valve is a single seated globe type valve that combines pressure & temperature reduction in one compact solution. The high pressure, high temperature steam which enters the main branch, is reduced in pressure and then spray water is injected immediately after pressure reduction. The high velocity and turbulent flow conditions data present immediately following the pressure reduction allow for rapid atomization and absorption of the spray water thus effectively desuperheating. the steam. Reduction of noise level due to mist formation by water is an added advantage.
