| BASIC PARAMETERS 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 RECOMMENDATIONS 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 feedwater) Instrument quality air is required Inlet isolation valve is needed Floor support to safety valve is needed |
FEATURES 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. |
