Product Description
Hydraulic butterfly valve is widely used in blast furnace gas pipeline system in metallurgical industry to prevent gas from tempering inside the pipe. In the power industry, in order to prevent the sudden reduction of the pressure in the steam turbine when the turbine unit is shedding load, the steam in the exhaust pipe and the heater is poured into the steam turbine, resulting in a vicious accident of breaking the turbine blade and damaging the turbine generator. Here the valve is used for emergency cutting off. When the system is in dangerous condition, the emergency valve can be implemented within 0.5 seconds to realize the reliable cut-off of the pipeline. Effectively prevent steam and condensate water from pouring back at the tail of steam turbine and protect the safety of steam turbine unit
