HP PRESSURE REDUCING DESUPERHEATER SYSTEM
GWY601/602 series HP pressurereducing desuperheater system is the ultimate selection for high pressure and temperature steam reduction service, the system employs many advanced concept and benefits to offer with best solution with effective performance of high pressure and temperature conditions. GWY601/602 adopted with highly pressure rated forged body of PRV with pilot plug design which gives supreme stability and controlling performance during continuous operation under high pressure and temperature, its design pressure is <14.0 MPa, design temperature is < 570 DegreeC, steam flow range is from 10% to 100%.
Available inlet pressure: P1<14.0 MPa
Available inlet temperature: T1<570 DegreeC
Available Inlet flow rate: 10%~100%
Outlet pressure controlling accuracy:
P2<0.98 MPa, accuracy range: ±0.04MPa
0.98 MPa<P2<3.82 MPa, accuracy range: ±0.06MPa
P2>3.82 MPa, accuracy range: ±0.15MPa
Outlet temperature controlling accuracy: ±4 DegreeC
Noise Level: <85 dbA
Minimum distance of Temperature Sensor from the point
of water injection should be 10 to 12 mtrs
It is recommended to install a strainer of 0.8 mm mesh
before water control valve
Spray water should be very clean (equivalent to boiler
Instrument quality air is required
Inlet isolation valve is needed
Floor support to safety valve is needed
The outstanding performance of GWY601/602 is achieved by high performance pressure reducing valve with unique design, the valve employs many advanced technology and procession method, designed of forged body, pressure-sealed bonnet, multihole cage guided, pilot plug structure and highly grade material selection, all benefits provides excellent stability and smoothly pressure reduction under high pressure and temperature service.
Unique plug and seat design allows for repeatable, reliable extended seat tightness, high thermal shock capability, and zero wear on seat while throttling.
For the desuperheatering part, the various types are available, offers with more selection for different working requirement and conditions.
The high performance feed water control valve is assembled and gives accurate water supplying to the spray nozzles for desuperheating.
