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.

Desuperheaters reduce the temperature of superheated process steam by introducing finely atomized cooling water droplets into the steam flow,Desuperheated steam is more efficient in the transfer of thermal energy, consequently desuperheaters are used to bring the outlet degree of superheat closer to that of saturation,In typical process plants, process steam is usually superheated or heated to a temperature above saturation. The difference,between the saturation temperature and the actual temperature of the steam is called 'superheat'.

Size Range : 15mm to 150mm

Prds valve, Pressure Reducing Valve - BTPR 100: Brightech™ Self-actuating, Internally pilot & piston operated, Globe type, Full lift, Spring & diaphragm actuated, Pressure reducingregulating valve, also known as Down-Stream Pressure Control Valve. Brightech™ series BTPR-100, internally pilot & piston operated pressure reducing valves are very compact in design & versatile type for accurate regulation with the widest possible range of flow

Steam PRDS is used for Steam Conditioning Services for reduction of pressure and temperature of steam. It is a combination of Control Valve for the pressure reduction purpose & atomizing nozzles, through which water is sprayed into steam for reducing the temperature. Combined PRDS helps to save the space and also cost of piping, as the unit is single and compact. For PRDS control system, there will be one Pressure loop and one temperature loop. Pressure control system includes pressure sensor, pressure transmitter, controller, IP Converter, Pressure gauges, etc. Temperature control system includes temperature sensor, transmitter, controller, IP Converter, Temperature gauges, etc. Spray water quantity required for the temperature reduction of the steam is controlled by separate spray water valve.

Pressure Rating : 150# to 2500#

PRESSURE REDUCING DESUPERHEATERS STATIONS (PRDS) Steam PRDS is used for Steam Conditioning Services for the reduction of pressure and temperature of steam. It is a combination of Control Valve for the pressure reduction purpose and atomizing nozzles through which water is sprayed into steam for reducing the temperature.
