Prds Valve Dealers in Pune (4 products available)

prds valve is the one wherein both the pressure reduction & temperature control is achieved in a single Unit.

Features Water injection up to 15%. Water injection from bottom provides easy access to water spray holes for maintenance. Only one set of gland packing reduce friction on spindle and assists smooth operation of valve. Rangeability 40:1 for both steam and water. No. of pressure reducing stages up to 3. Predicted noise level below 85 dB. Approved under IBR (Indian Boiler Regulation Act).

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.
