PUREVAL — PRDSH & PRDS VALVE
Pressure Reducing & De-Superheating Stations (PRDS) & VALVES
PRDS and PRDSH refer to systems that simultaneously reduce high-pressure superheated steam to a lower, usable pressure and temperature. These stations are critical for protecting downstream equipment and ensuring maximum heat transfer efficiency by converting superheated steam into saturated steam.
PureVAL
PureVAL PRDS and PRDSH systems provide precise, integrated pressure and temperature control in a compact design to maximize heat transfer efficiency. Built with IBR-approved materials and high rangeability, they ensure long-term operational safety and reduced maintenance costs for demanding steam applications.
PRDSH & PRDS VALVE
Our Combined Pressure Reducing & De-Superheating Station uses a revolutionary single piece design to eliminate all the constraints associated with two-piece systems like – Poor & inefficient mixing of cooling water, water-hammer, wet steam etc.
Every PRDS System is custom engineered to suit your exact pressure and temperature requirements. Both – steam & temperature – reduction (i.e. De-Superheating) are done in a single valve, making it an extremely efficient, cost effective and compact system.
All upstream & downstream pipe work & fittings are adequately sized to ensure that only the required pressure drop occurs across the control valve itself.
