Spray Water Control Valve
Specifications:
Nominal diameter: 3/4″-6″
Nominal pressure: ANSI 150Lb ~ 4500Lb
Body type: straight-through way type, angle type
Operation temperature: 150℃~450℃
Flow characteristics: equal percentage
Actuator: electric or pneumatic actuator
Leakage: meet ANSI B16. 104 V leakage(VI level seal is available)
Features:
Heat efficiency lose: due to the drop of throttle steam temperature caused by spray valve leakage, heat efficiency will be affected and extra heat will be needed for the boiler to keep the throttle steam temperature at the set point.
Temperature control: poor control of the steam temperature may also affect the high pressure steam pipe and turbine.
When the pressure is higher than 12.4Mpa(1800psi), each temperature change of 19-22℃（30-40℉） would lead to 1% heat efficiency change.
Higher maintenance cost: frequent replacement and maintenance will be needed due to the plug erosion damage.
