Prds Valve With Bottom Entry

Salient Features Of PRDS Valve with Bottom Entry :-
a c Rang ability 40: 1 for both steam and water
a c Water Injection in Vena contract zone
a c High turbulence in expanding steam is ideal for optimum evaporation of spray water
a c A rough control of water i.e. instantaneous change in water flow corresponding to steam flow is possible through the stroke of the plug. The final temperature control is realised through the water injection Valve
a c Multi-stage trim (2-5 steps) design ensures sub critical pressure reduction from 0- 100% capacity for all stages. The sub critical pressure reduction is an important quality feature.
a c Water-steam fog absorbs noise resulting reduction in noise level upto 6 dB
a c Maintenance friendly design easy access to valve internals
a c Water injection upto 12% of steam
a c Suitable when injection water is available at higher pressure and a relatively high temperature.
