Product description
T series control valve
1. Introduction
T series control valves are mainly used in thermal power plants with high regulation characteristics, high temperature, high pressure difference and flow regulation, mainly including feed water control valve, spray water control valve and T947H-10, T968H, T961H control valve, etc.
The feed water control valve is installed in the main feed water system of the boiler to regulate the feed water flow according to the change of the boiler load; the spray water control valve is installed in the spray pipe of the spray desuperheater to regulate the steam temperature of the boiler superheater or reheater by regulating the cooling water flow; the T947H-10, DN50, DN80 and PN10 control valves are installed in the oil return pipe of the oil fired boiler to regulate the oil return flow; T968H and T961H control valves are installed on the feed water bypass of the constant speed pump to regulate the feed water flow when the boiler is started up for low load operation.
