ENGINEERED STEAM SOLUTIONS

Pressure Reducing Stations

Steam at high pressure occupies less volume per kg than steam at lower pressure. Thus steam is generated & distributed at high pressure than required. Just before the use its pressure is reduced to achieve the Process Requirements. 

Pennant offers Pressure reducing Station with Control Valve & Pressure Control Loop which ensures the required accurate Pressure Control to fulfill the Process Requirements.

Features

  • Systems supplied are complete and ready to fit on site.
  •  Use of control valve with pressure control loop instrumentation ensures accurate pressure control with use of auxiliary energy. 
  •  Single stage pressure reduction results in compact system. 
  •  Design ensures that the total required pressure drop occurs in control valve & safety valve protects the system against any failure. 
  •  Systems available for low as well as high pressure drops. 
  •  All systems are manufactured & 100% hydro tested. 
  •  Each unit custom engineered & designed to meet specific process requirements.
